Efficacy and safety of oral propranolol and topical timolol in the treatment of infantile hemangioma: a meta-analysis and systematic review

BackgroundPropranolol, a nonselective β-blocker, is the first-line treatment for infantile hemangioma (IH). Topical timolol has recently been proposed as a novel IH treatment with fewer adverse effects. This study was conducted to compare the efficacy and safety of oral propranolol and topical timolol for treating IH.MethodsStudies were included after searching PubMed, Embase, Web of Science, and the Cochrane Library via the keywords of “propranolol”, “timolol”, “infantile hemangioma” and their synonyms. A meta-analysis with pooled odds ratios was performed using the fixed-effect model.ResultsSeven articles with 2071 patients were included in this meta-analysis. Compared with topical timolol, oral propranolol had a greater response rate (OR = 2.12, P < 0.001), but it was also associated with a greater risk of adverse events (OR = 2.31, P < 0.001). For superficial IH, timolol demonstrated similar efficacy to propranolol (OR = 1.28, P = 0.34) but with fewer adverse events (OR = 2.30, P = 0.001). Additionally, compared with topical timolol, propranolol at a dosage of 2 mg/kg/d had a better response rate (OR = 2.62, P < 0.001), whereas the 1.0∼1.5 mg/kg/d propranolol group showed no significant difference (OR = 1.34, P = 0.38).ConclusionOral propranolol presents superior therapeutic efficacy in the treatment of IH compared to topical timolol. However, topical timolol can serve as an alternative to oral propranolol for treating superficial IH, providing similar efficacy with fewer adverse effects. Additionally, propranolol at a dosage of 2 mg/kg/d offers greater efficacy with a comparable safety profile, whereas the 1.0∼1.5 mg/kg/d propranolol dosage shows no significant difference in efficacy compared to timolol but is associated with more adverse events.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42024603724, identifier CRD42024603724.

Reconsideration of the clinical management of hepatic hemangioma

In this letter, we comment on the article by Zhou et al that was published in the recent issue of the World Journal of Gastrointestinal Surgery . This article proposes a new clinical grading system based on a multidisciplinary team, which prompts us to rethink the clinical management of hepatic hemangioma. Hepatic hemangioma is the most common benign solid liver tumor. In general, follow-up and observation for the vast majority of hepatic hemangioma is reasonable. For those patients with symptoms and severe complications, surgical intervention is necessary. Specific surgical indications, however, are still not clear. An effective grading system is helpful in further guiding the clinical management of hepatic hemangioma. In this article, we review the recent literature, summarize the surgical indications and treatment of hepatic hemangioma, and evaluate the potential of this new clinical grading system.

Use of modified human hemangioma tissue cultures and human umbilical vein endothelial cell cultures to gain mechanistic insights into imiquimod treatment for infantile hemangioma.

Infantile hemangiomas (IH) are a common entity encountered by dermatologists, otolaryngologists, and other surgeons. Oral propranolol is a mainstay of treatment for IH and is well-tolerated, though propranolol-refractory IH and other drug-related adverse events are documented and can limit its usage. There are few in vitro testing systems for putative treatment agents. To address this, we modified a tissue culture system for human hemangioma treatment testing to evaluate the treatment impact of the immune modifier, imiquimod. Human umbilical vein endothelial cells (HUVEC) and hemangioma cultures were treated with several concentrations of imiquimod followed by MTT assays, reporter gene assays, PCR, ELISA, and Western blotting for IL-8, VEGF, Cyclin D1, and IFNα and immunohistochemistry for Cyclin D1 and Ki-67. HUVEC showed acute decreases in IL-8, VEGF, and Cyclin D1 promoter activity and increases in IFNα mRNA after imiquimod treatment. Hemangioma samples showed no change in Ki-67 or Cyclin D1 staining after treatment with imiquimod after 27 d, with significantly increased IL-8 and VEGF. From this preliminary analysis, we discerned that hemangioma tissues can be grown in tissue culture and used for drug treatment studies. We also conclude acute and chronic modulation of cell cycle, angiogenesis factors, and immunostimulatory conditions may be associated with imiquimod mechanisms of action in hemangioma involution.

Hemangioma in Children: Literature Review

Hemangioma is a vascular anomaly that is benign and generally occurs in children. ISVVA 2018 classifies vascular anomalies into two categories, namely vascular malformations and vascular tumors (hemangioma). The prevalence of hemangioma is higher in low birth weight babies, premature babies, and girls. Several theories suggest that hemangiomas are caused by vasculogenesis and angiogenesis or an imbalance between angiogenic and antiangiogenic factors. Hemangiomas grow through a proliferation phase, involution phase, and post-involution phase. Hemangioma classification is based on the depth of the lesion, time of appearance of the lesion, distribution of the lesion, and its relationship to syndrome complication.. Diagnosis of hemangioma is based on anamnesis, physical examination, and supporting examinations which include USG, MRI, and CT-Scan. Hemangiomas that lead to complications should require immediate treatment. Hemangioma treatment can be done with topical therapy, systemic therapy (propranolol, corticosteroids, β-blockers, vincristine, rapamycin), laser therapy (PDL, diode, Nd: YAG, argon, KTP, CO2, IPL), and other treatments consisting of from surgical and non-surgical procedures (bleomycin injection).

Safety of Prior Propranolol Therapy for Infantile Hemangioma.

Propranolol has been the primary treatment for infantile hemangioma (IH) since 2008. Prior studies have investigated the effects in late childhood of propranolol therapy given in infancy for IH, including neurocognitive dysfunction, sleep disorders, and hypoglycemia. However, few studies have determined the risk of these adverse effects later in life. Using the TrinetX database, we studied the risk of growth impairment, sleep disorders, learning disabilities, and diabetes mellitus in children aged 10-17 years who had received propranolol for IH in infancy. The maximum age of 17 years was chosen for the study, as propranolol was established as a treatment for IH in 2008. The results showed no statistically significant risk of growth impairment, sleep disorders, learning disabilities, or diabetes mellitus in IH patients treated with propranolol. These findings support existing evidence that propranolol therapy given in infancy for IH is not associated with long-term adverse effects up to age 17 years in the studied patient population.

Efficacy and safety of atenolol versus propranolol for treatment of infantile haemangioma: A narrative review.

Infantile haemangiomas (IH) remain the most common benign vascular tumours in childhood. While most IH can be managed conservatively, a proportion of these lesions can cause disfigurement, ulceration or functional impairment, requiring prompt intervention. Propranolol, a lipophilic non-selective beta blocker, has been regarded as first-line therapy, following a serendipitous discovery of its use for IH in 2008. While efficacious, it has been associated with adverse effects such as hypoglycaemia, bronchospasm, sleep disturbances and agitation in infant trials. Hence, atenolol, a hydrophilic beta-1 selective blocker, has demonstrated similar efficacy and potentially greater tolerability, being less likely to cause sleep disturbances given its inability to cross the blood brain barrier, and a decrease in bronchial reactivity. The purpose of this review is to explore and critique the current knowledge on the efficacy and safety of propranolol against atenolol in children with IH. A total of seven studies comparing the two beta-blockers were identified in our search. Atenolol appeared to be as efficacious as propranolol and was associated with fewer central nervous system and bronchial-related adverse events. Further research exploring the optimal dosing for atenolol, particularly for ulcerated or syndromic IH, as well as incidence and management of rebound growth would be beneficial.

Microsurgical treatment of spinal intradural capillary hemangioma: A consecutive case series of 18 patients and literature review

PurposeIntradural capillary hemangioma is a rare condition with unclear etiology. Although intradural capillary hemangiomas are benign, they exhibit significant proliferative activity, and their clinical significance should not be underestimated. MethodsWe report a series of spinal intradural capillary hemangiomas to illustrate the characteristics, surgical management, and outcomes. MethodsA total of 18 consecutive patients who underwent microsurgical treatment were retrospectively reviewed. Patient characteristics were recorded in each case, including presenting symptoms, imaging findings, neurologic status, a surgical procedure performed and follow-up. ResultsThere were 11(61.1 %) male and 7(38.9 %) female patients, with the ages ranging from 25 to 62 years. The thoracic spine was the most commonly affected site, accounting for 77.8 % (14/18) of the cases. 9 tumors were identified as intradural extramedullary, 3 tumors as intramedullary, and 2 tumors as both extramedullary and intramedullary. There were also 4 cases of tumors localized to the cauda equina. Clinical presentations included back pain, sensory deficits, weakness and gait ataxia with a duration of symptoms ranging from 1 to 12 months. The lesion was hypointense or isointense with the spinal cord on T1- weighted images and hyperintense on T2-weighted images and showed intense enhancement after contrast medium injection. All patients underwent surgical treatment, and no significant postoperative complications were observed. Postoperatively, patients were followed up for an average of 44 months. Follow-up showed that the majority of patients experienced significant improvement in neurological function, with no cases of recurrence. ConclusionSurgical resection is typically the preferred method for treating spinal intradural capillary hemangiomas. Complete resection can relieve spinal cord compression and minimize the risk of recurrence.

Algorithm-based Management of Infantile Hemangiomas: Reducing Sequelae and Surgical Interventions

Background: In Japan, oral propranolol (PPL) and pulsed dye laser are available for infantile hemangioma (IH) treatment without patient cost-sharing. However, no standardized algorithm exists to guide treatment selection that balances efficacy, potential side effects, and aesthetic risks. This study presents a comprehensive approach utilizing a treatment algorithm and aesthetic risk scoring system. Methods: This retrospective study analyzed outcomes from 156 patients with IHs. Oral PPL was used in IH patients with functional issues, whereas the rest underwent an aesthetic risk assessment that categorized them into low-, moderate-, or high-risk groups to guide treatment choices. Final treatment decisions depended on parental preference. The outcomes of algorithm-compliant and noncompliant patients were compared statistically. Results: The risk score's interrater reliability was 0.973 (95% confidence interval 0.933–0.992), with a mean intrarater reliability of 0.968 ± 0.027 and a mean evaluation time of 14.1 ± 5.0 seconds per case. Among the 156 patients, 88% pursued the algorithm-recommended treatment, whereas 12% opted for different approaches. Algorithm-compliant patients experienced significantly fewer sequelae than did noncompliant patients (5% versus 33%, P < 0.001). Compared with noncompliant patients, algorithm-compliant patients tended to require shorter treatment durations (17.9 versus 25.4 mo, P = 0.08) and fewer laser sessions (5.8 versus 7.2, P = 0.30), with a younger age at resolution (21.3 versus 29.0 mo, P = 0.08). Conclusions: Aesthetic concerns can be crucial for patients with IHs. This study introduces a comprehensive IH management algorithm to reduce the sequelae requiring surgical interventions and improve patients’ quality of life.

Oxidized cellulose microneedle patch combined with vascular embolization and local delivery of timolol maleate for hemangiomas

Hemangiomas are superficial tumors characterized by dense vascular structures that often affect the patient's aesthetic appearance due to the obvious red appearance on the skin. Current treatments, especially timolol maleate in the form of eye drops and hydrogels, suffer from low transdermal drug delivery rates, resulting in prolonged treatment time. To address this challenge, our study introduced a soluble microneedle patch with dextran as the main material to form microcatheters for sustained delivery of timolol maleate. In addition, we proposed a vascular embolization strategy to disrupt the blood supply in hemangiomas. Oxidized cellulose (C-cellulose) was selected for its excellent hemostatic properties. We incorporated C-cellulose into dextran microneedles to facilitate thrombosis in the vascular-rich areas of hemangiomas. The innovative microneedle patch we developed can penetrate the skin to a depth of 430 μm and dissolve rapidly within 3 minutes, ensuring direct drug delivery to the subcutaneous layer. Notably, the treated skin area regained its original appearance within two hours after treatment. In addition to excellent skin permeability and rapid dissolution, these patches significantly promoted apoptosis and inhibited cell migration in mouse hemangioendothelioma EOMA cells. Our results demonstrate that this approach not only achieves significant tumor inhibition in a mouse hemangioma model, but also represents a more effective, convenient, and non-invasive treatment option. Therefore, dextran/C-cellulose/timolol maleate microneedle patch (MNs/Timolol) has broad clinical application prospects in the treatment of hemangiomas, minimizing the risk of additional damage and improving treatment efficacy.

3D Slicer and 3D printing localization combined with neuroendoscopic surgery for the treatment of deep cerebral cavernous hemangioma

To explore the advantages and disadvantages of 3D Slicer reconstruction and 3D printing localization combined with transcranial neuroendoscope in the surgical treatment of deep cerebral micro cavernous hemangiomas. Method The clinical data of patients with deep cerebral micro cavernous hemangiomas treated by our hospital from June 2022 to February 2023 using 3D Slicer reconstruction and 3D printing localization technology combined with transcranial endoscopic surgery were retrospectively analyzed. A total of 5 cases with complete data were collected, including 2 males and 3 females, aged 9–59 years. All 5 patients had deep supratentorial cavernous hemangiomas with a diameter of less than 1.5 cm, and had clinical symptoms such as headache or epilepsy, and had been diagnosed by CT or MRI. Repeated bleeding from small cavernous hemangiomas in the deep brain can lead to clinical symptoms such as recurrent headache and epilepsy, and is required surgical treatment. However, cavernous hemangiomas often have smaller lesions and are difficult to locate in the deep part. Without neuronavigation, surgery can become extremely difficult. Our team’s newly developed 3D Slicer reconstruction and 3D printing localization technology which could provide new options for surgical treatment of small cavernous hemangiomas or other small lesions in the deep brain, but its accuracy and safety still need to be verified by further clinical research.

Solid Lipid Nanoparticles Based Topical Hydrogel for Potential Treatment of Infantile Hemangioma

Solid Lipid Nanoparticles Based Topical Hydrogel for Potential Treatment of Infantile Hemangioma

Endoscopic injection of lauromacrogol foam sclerotherapy for rectal cavernous hemangioma: A case report.

Rectal cavernous hemangioma is a rare, benign vascular disease that seldom causes lower gastrointestinal bleeding, characterized by a high rate of misdiagnosis and missed diagnoses. Surgical treatment is considered to be relatively effective; however, it is accompanied by certain employed in the treatment of superficial hemangioma, boasting the advantages of minimally invasive surgery, including safety, effectiveness, reduced trauma, and rapid recovery. However, there is a lack of literature regarding the application of foam sclerosing agents for gastrointestinal hemangiomas. We present a case of a 60-year-old male who was admitted to our hospital with a history of recurrent hematochezia for >1 year and worsening symptoms for 1 week. The patient's medical history was unremarkable. Following colonoscopy, nuclear magnetic resonance imaging, computed tomography, and other examinations, the final diagnosis was rectal cavernous hemangioma. Due to the patient's refusal of surgery, endoscopic foam sclerotherapy using a lauromacrogol injection was performed after obtaining informed consent from the patient and their relatives. Post-sclerotherapy, hematochezia symptoms ceased, and no adverse reactions were observed. Two months later, colonoscopy and nuclear magnetic resonance imaging showed that the hemangioma had almost completely disappeared, with only a small amount of tumor remnants, yielding a satisfactory curative effect. Our findings indicate that endoscopic injection of a lauromacrogol foam sclerosing agent is a safe, effective, and minimally invasive treatment option for gastrointestinal cavernous hemangiomas.

R(+) Propranolol decreases lipid accumulation in hemangioma-derived stem cells.

Infantile hemangioma (IH) is a benign vascular tumor that undergoes an initial rapid growth phase followed by spontaneous involution. A fibrofatty residuum remains in many tumors and often necessitates resection. We recently discovered that R(+) propranolol, the non-β blocker enantiomer, inhibits blood vessel formation of IH patient-derived hemangioma stem cells (HemSC) xenografted in mice. HemSC are multipotent cells with the ability to differentiate into endothelial cells, pericytes, and adipocytes. We investigated how R(+) propranolol affects HemSC adipogenic differentiation and lipid accumulation, in vitro and in a preclinical murine model for IH. We conducted a 10-day adipogenesis assay on 4 IH patient-derived HemSCs. Oil Red O (ORO) staining was used to identify the onset and level of lipid accumulation in HemSC while quantitative real-time polymerase chain reaction was conducted to determine the temporal expression of key factors implicated in adipogenesis. 5-20µM R(+) propranolol treatment was added to HemSC induced to undergo adiogenesis for 4 and 8 days, followed by quantification of lipid-stained areas and transcript levels of key adipogenic factors. We immunostained for lipid droplet-associated protein Perilipin 1 (PLIN1) in HemSC-xenograft sections from mice treated with R(+) propranolol and quantified the area using ImageJ. We found that different patient-derived HemSC exhibit a robust and heterogenous adipogenic capacity when induced for adipogenic differentiation in vitro. Consistently across four IH patient-derived HemSC isolates, R(+) propranolol reduced ORO-stained areas and lipoprotein lipase (LPL) transcript levels in HemSC after 4 and 8 days of adipogenic induction. In contrast, R(+) propranolol had no significant inhibitory effect on transcript levels encoding adipogenic transcription factors. In a pre-clinical HemSC xenograft model, PLIN1-positive area was significantly reduced in xenograft sections from mice treated with R(+) propranolol, signifying reduced lipid accumulation. Our findings suggest a novel regulatory role for the R(+) enantiomer of propranolol in modulating lipid accumulation in HemSC. This highlights a novel role of R(+) propranolol in the involuting phase of IH and a strategy to reduce fibrofatty residua in IH. Propranolol is the mainstay treatment for infantile hemangioma (IH), the most common tumor of infancy, but its use can be associated with concerning β-blocker side effects.R(+) propranolol, the enantiomer largely devoid of β-blocker activity, was recently shown to inhibit endothelial differentiation of hemangioma-derived stem cells (HemSC) in vitro and reduce blood vessel formation in a HemSC-derived xenograft murine model of IH. R(+) propranolol inhibits lipid accumulation in HemSC in vitro.R(+) propranolol does not affect mRNA transcript levels of key adipogenic transcription factors in differentiating HemSC in vitro.R(+) propranolol reduces lipid accumulation in a pre-clinical xenograft murine model of IH. The R(+) enantiomer of propranolol could be advantageous in terms of reduction in β-adrenergic side effects and fibrofatty tissue formation in the involuting phase of IH.Less fibrofatty residua might reduce the need for surgical resection.Disfigurement and associated psychosocial impacts might be improved in this young patient cohort.

Development of a New Non-Invasive Approach to Treat of Infantile Hemangioma with Growth-Inhibiting Endogenous Factors (Non-Invasive Approach to Treat of Infantile Hemangioma with Endogenous Factors)

Background: Infant hemangioma is a benign vascular tumor, the main reason for the development of which is genetic disorders occurring in embryogenesis. It should be noted that all methods of treating the disease, both general and local, have potential negative risks and side effects. The identification of endogenous regulatory factors and researching the possibilities of using them for treatment is relevant. There is the thermostable proteins complex (TPC) which has been identified in the cells of phylogenetically distant almost all organisms, which has the ability to decrease the mitotic activity of cells by inhibition of transcription. In the experimental model of hemangioma, it has been established that inhibition of capillary growth can only be achieved by injection. The aim of the work was to develop a new, less invasive method of hemangioma treatment with endogenous factors.

Microneedle delivery system with rapid dissolution and sustained release of bleomycin for the treatment of hemangiomas

Hemangioma of infancy is the most common vascular tumor during infancy and childhood. Despite the proven efficacy of propranolol treatment, certain patients still encounter resistance or face recurrence. The need for frequent daily medication also poses challenges to patient adherence. Bleomycin (BLM) has demonstrated effectiveness against vascular anomalies, yet its use is limited by dose-related complications. Addressing this, this study proposes a novel approach for treating hemangiomas using BLM-loaded hyaluronic acid (HA)-based microneedle (MN) patches. BLM is encapsulated during the synthesis of polylactic acid (PLA) microspheres (MPs). The successful preparation of PLA MPs and MN patches is confirmed through scanning electron microscopy (SEM) images. The HA microneedles dissolve rapidly upon skin insertion, releasing BLM@PLA MPs. These MPs gradually degrade within 28 days, providing a sustained release of BLM. Comprehensive safety assessments, including cell viability, hemolysis ratio, and intradermal reactions in rabbits, validate the safety of MN patches. The BLM@PLA-MNs exhibit an effective inhibitory efficiency against hemangioma formation in a murine hemangioma model. Of significant importance, RNA-seq analysis reveals that BLM@PLA-MNs exert their inhibitory effect on hemangiomas by regulating the P53 pathway. In summary, BLM@PLA-MNs emerge as a promising clinical candidate for the effective treatment of hemangiomas.Graphical

Beta-blockers for the treatment of infantile haemangiomas in premature infants.

Beta-blockers have been established as a treatment of infantile haemangiomas (IH) since its serendipitous discovery for use in IH in 2008. However, data on the safety of these beta-blockers for use in IH in preterm infants are scarce. A retrospective study was performed to review the safety of oral propranolol and topical timolol in the treatment of IH in a cohort of preterm infants treated at our tertiary paediatric hospital. It was observed that there was an increased risk of adverse events amongst the preterm infants with chronic lung disease, retinopathy of prematurity and gastroesophageal reflux, when treated with oral propranolol.

Comparative Outcomes of Propranolol Monotherapy and Combined Therapy with Intralesional Triamcinolone in Infantile Hemangioma

Background: Infantile Hemangiomas (IHs) are the most common vascular tumors of infancy. Oral propranolol has achieved great success in treating IHs since 2008. Recently combined oral propranolol with intralesional injection of Triamcinolone acetonide is the effective method of treatment for infantile Hemangioma with minimal adverse effects. Objectives: To observe the outcome of Propranolol monotherapy and combined therapy with intralesional Triamcinolone in Infantile Hemangioma. Materials and Methods: This prospective study was carried out in the Department of Pediatric Surgery, Sylhet MAG Osmani Medical College Hospital, Sylhet, during the period from January 2018 to December 2019. It included 42 infantile hemangioma patients divided into two groups: Group A (21) treated with oral propranolol, and Group B (21) treated with oral propranolol plus intralesional triamcinolone acetonide. Patients were followed up at regular intervals for 6 months. Results: The data of two groups of patients with IH were compared in the study. The demographic variables, including median age, sex, size, type, and site of IH, were comparable between the two groups. This showed that pre-treatment complications were slightly higher in Group B but not significantly different. Superior size reduction was observed in Group B (71.4% vs. 38.1%), though the difference was not significant statistically. Group B had excellent color regression, which was significantly higher compared to the other group (90.5% vs. 9.5%, p < 0.001). The mean treatment cost was higher in Group B, which was 187.86. taka compared to 124.76. taka in Group A (P value was <0.001). In summary, Group B had better color regression of the pinprick but at a higher cost of treatment as compared to Group A, and other parameters were almost equal in both groups. Conclusion: Combined propranolol and intralesional Triamcinolone is more effective compared to propranolol alone in the treatment of IHs.

Cardiac Evaluation before and after Oral Propranolol Treatment for Infantile Hemangiomas.

Background: Most recent clinical practice guidelines addressing the management of infantile hemangiomas (IHs) recommend oral propranolol, a non-selective beta-adrenergic antagonist, as first-line treatment. However, few reports have provided continuous follow-up data regarding cardiac evaluations. Methods: Sixty-four patients diagnosed with IHs and treated with oral propranolol before 2 years of age at the Department of Pediatrics, Kangbuk Samsung Hospital (Seoul, Republic of Korea), with regular examinations between 2017 and 2021, were included. Cardiac evaluations, including electrocardiography, Holter monitoring, chest X-ray, and echocardiography, were performed. Results: Sixty-four patients with IHs successfully underwent continuous follow-up cardiac evaluations. The median age at diagnosis was 2 weeks (1 day to 34.3 weeks). The median age at treatment initiation was 13.6 weeks (2.4-87.9 weeks), the mean longitudinal diameter of hemangioma at diagnosis was 2.8 ± 2.1 cm (0.3-12.0 cm), and the mean percentage of size decrease after 1 year of oral propranolol treatment was 71.8%. None of the 64 patients experienced severe adverse side effects during propranolol treatment. There was no statistically significant differences in echocardiographic function and electrocardiographic data after treatment. Conclusions: Propranolol treatment ≥6 months was effective and safe without significant cardiac toxicity in the treatment of patients with infantile hemangiomas.

Cryocarboxy Surgery: A New Armamentarium in the Treatment of Infantile Hemangiomas of the Lips.

Cryotherapy was reported in the treatment of infantile hemangiomas by many studies using liquid nitrogen as a cryogen. To evaluate the outcome of cryo-carboxy surgery in treatment of infantile lip hemangiomas. In this study, we present the use of carbon dioxide as the cryogen in 50 patients with infantile hemangiomas of the lips with successful results. The patient evaluation was done including the improvement in color, texture, and volume of the lesion and each of the three parameters was given a score on a 4-point scale; excellent, good, fair, or poor. The average evaluation score of our patients was excellent in 37 (74%) cases and good in 13 (26%) cases. We had no fair or poor results. There was no postprocedural hypopigmentation in any of the patients with lesions limited to the mucosa and Vermillion. In contrast, all cases with lesions extending to the lip skin (10 cases) experienced hypopigmentation which resolved spontaneously within 3 months. No complications were observed in our cases during the follow-up period and no cases, during the follow-up period, showed regrowth of the treated lesions. We can conclude that, cryo-carboxy surgery is an effective safe new tool in the armamentarium of the treatment of infantile hemangiomas of the lips with successful results.
