Erosive pustular dermatosis of the scalp may not be mutually exclusive with other dermatoses

Erosive pustular dermatosis of the scalp is an uncommon neutrophilic process representing a diagnostic and therapeutic challenge. It often occurs in older patients with prior sun exposure and manifests with hyperkeratosis and crust that may be difficult to distinguish from other inflammatory or neoplastic processes. Although erosive pustular dermatosis of the scalp may respond effectively to high potency topical steroids or other antiinflammatory regimens, caution is advised to avoid overlooking differential diagnoses that may not be mutually exclusive, especially squamous cell carcinoma.

FR -Aparición de herpes zoster secundario a la aplicación de ingenol mebutato en gel: comunicación del primer caso europeo

An 85-year-old Caucasian man was referred to our clinic due to lesions clinically compatible with actinic keratoses (AKs), so one course of ingenol mebutate (IM) 0.015% gel was prescribed. One week after the treatment, the patient developed multiple painful vesicular lesions predominantly on the left half of the neck, compatible with a herpes zoster (HZ). Due to the location and clear temporal sequence, HZ was attributed to IM. Adverse skin reactions to IM include erythema, post-inflammatory hyperpigmentation and scarring, all due to local inflammation. Otherwise erosive pustular dermatosis of the scalp, bullous reaction and squamous cell carcinoma secondary to IM application have been described. No case of HZ related to IM has ever been reported before. In August 2015, based on the notification of 20 cases of HZ during the post marketing experience in USA, FDA included HZ as an adverse effect in the American prescribing information for IM. However, until now, this side effect has not been introduced in the European information. To our knowledge, we report the first European case of reactivation of the HZ caused by IM gel in an immunocompetent patient.

Erosive pustular dermatosis of the scalp induced by gefitinib: case and review of the literature

Gefitinib is a selective tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR) used for the treatment of malignant neoplasms. The most frequent skin complication during gefitinib therapy is an acneiform papulopustular eruption, usually distributed in the seborrheic areas but occasionally widespread. We report a patient with erosive pustular dermatosis of the scalp, a neutrophil-mediated skin disease presenting with sterile pustules evolving into erosions and crusts on the scalp, during treatment with the EGFR inhibitor gefitinib for lung cancer. A literature review of the drug-induced cases of this rare entity is provided.

How well do treatments for erosive pustular dermatosis of the scalp work?

Erosive pustular dermatosis of the scalp (EPDS) is a skin disease that causes non‐healing wounds on the scalp. It may be more common than previously thought, as it can be misdiagnosed. EPDS usually affects older patients with lots of sun damage, and it may also be caused by injury, surgery, or certain treatments used by dermatologists, such as 5‐fluorouracil cream, which is used to treat pre‐cancerous lesions.

Erosive pustular dermatosis of the scalp: causes and treatments.

Erosive pustular dermatosis of the scalp is a rare condition which primarily affects older women after local trauma and has historically been treated with topical steroids. As it is a rare entity and resembles other dermatologic conditions, it may easily be misdiagnosed. Identifying the causes and evaluating the efficacy of treatments of erosive pustular dermatosis of the scalp (EPDS) is of great importance to both avoid misdiagnosis and ensure optimal treatment of this rare condition. There are numerous causes. In addition to surgeries and physical injuries, topical and procedural treatments for actinic keratoses and androgenetic alopecia can trigger the development of lesions. There are also documented associations with several autoimmune and systemic conditions. Besides corticosteroids, topical tacrolimus and photodynamic therapy were the most commonly used treatments for EPDS. They were effective with few recurrences and adverse effects. Other successful treatment options were topical dapsone, silicone gels, calcipotriol, acitretin, and isotretinoin. Oral dapsone can be used in cases of disseminated disease. Zinc sulfate should be considered with low-serum zinc levels. While cyclosporine was effective, there were adverse effects that may limit its use. It is important for dermatologists to be aware of the wide array of potential causes of erosive pustular dermatosis and include it on their differential. Additionally, although high-potency topical steroids have been historically used as the first-line treatment, there are many other effective treatments that may avoid recurrence and skin atrophy, particularly in the elderly population.

Therapeutic options for erosive pustular dermatosis of the scalp: a systematic review.

Erosive pustular dermatosis of the scalp (EPDS) is a chronic condition characterized by erosive plaques and subsequent scarring alopecia as a result of local trauma or inflammation. A number of therapeutic approaches have been described in the literature but there is no consensus of opinion on optimal treatment of the disease. To provide evidence-based recommendations for topical and systemic treatment of adult patients with EPDS by performing a systematic review. The MEDLINE, MEDLINE In-Process, Embase and Cochrane databases were searched from inception to 26 June 2019 in accordance with the PRISMA guidelines for studies involving adult patients treated for EPDS with at least one reported response to treatment. The study was registered on PROSPERO. Texts were reviewed independently by two authors. The risk of bias and quality of the studies were assessed using the Quality Appraisal Checklist for Case Series Studies. In total 75 studies were included, involving 168 patients. Many treatments have been reported in the literature, with varying degrees of therapeutic success. The results were highly heterogeneous and methodological quality was very low. We were unable to perform a meta-analysis on the data. The limited available evidence supports use of topical corticosteroids, with or without oral zinc, followed by maintenance therapy with topical calcineurin inhibitors as being effective in managing this condition. Topical photodynamic therapy is also potentially beneficial in the management of EPDS. Prospective, comparative, randomized controlled trials are required in order to provide further evidence to guide treatment.

Case reports on erosive pustular dermatosis of scalp: a cross sectional study at a tertiary care centre

<p class="abstract">Erosive pustular dermatosis of the scalp (EPDS) has been reported as a rare chronic and progressive non-infectious inflammatory condition of the actinically damaged scalp characterized by crusts, erosions and pustules. It tends to occur on the scalp of older people who have usually been treated for diffuse actinic damage and actinic keratoses. The list of possible differential diagnosis is long and includes tinea capitis, folliculitis decalvans, neutrophilic dermatosis, autoimmune vesiculobullous disorders, malignancy etc. Notoriously difficult to treat, these cases tend to be chronic and progressive. These patients often present after repeated treatment to various scalp dermatosis that doesn’t result in clearing instead persistence and perpetuation of the process. A cross sectional prospective study was conducted in department of dermatology in a tertiary care centre in which six cases of EPDS attending outpatient department from 2017 to 2019 were included. EPDS is more common but under recognized condition, hence less cases are reported till date. Increased awareness of and proper diagnosis of this condition changes the approach towards these patients, protects the scalp from involuntary insults and other precipitating factors that hinders with a better outcome.</p>

Erosive pustular dermatosis of the scalp: a multicentre study.

Erosive pustular dermatosis of the scalp (EPDS) is characterized by crusted erosions or superficial ulcerations that lead to scarring alopecia. We performed a multicentre retrospective clinical study including 56 patients (29 females and 27 males, mean age 62.7) with a confirmed EPDS in order to describe epidemiology, clinical findings and therapeutic choices of this disease. Mechanical/chemical trauma was reported in 28.6%, a previous infection in 10.7%, a previous cryotherapy in 5.4% androgenetic alopecia in 48.2% and severe actinic damage in 25%. Trichoscopy showed absence of follicular ostia, tufted and broken hair, crusts, serous exudate, dilated vessels, pustules and hyperkeratosis. Histopathology revealed three different features, depending on the disease duration. The most prescribed therapy was topical steroids (62.5%), followed by the combination of topical steroids and topical tacrolimus (8.9%), systemic steroids (7.1%) and topical tacrolimus (5.4%). A reduction of inflammatory signs was observed in 28 patients (50%) treated with topical steroids and in all three patients treated with topical tacrolimus. The relatively high number of patients collected allowed us to identify a better diagnostic approach, using trichoscopy and a more effective therapeutic strategy, with high-potency steroids or tacrolimus, which should be considered as first-line treatment.

Erosive Pustular Dermatosis of the Scalp After Excision and Skin Grafting of Scalp Squamous Cell Carcinoma

Abstract Introduction: Erosive pustular dermatosis of the scalp (EPDS) is an uncommon condition with unknown etiology. The clinical exclusive diagnosis needs to be differentiated from similar diseases. Here, we present a case of EPDS after surgical treatment of scalp squamous cell carcinoma. Case presentation: A 68-year-old woman presented with an eight-month history of a chronic scalp eruption. She had been diagnosed as squamous cell carcinoma by biopsy nine months ago, and had been treated by surgical excision and skin grafting. One month later, she was referred for evaluation of the newly enlarged lesion which was observed at the skin grafting site. She was diagnosed of EPDS based on characteristics of lesions, clinicopathological findings and laboratory data. The condition had clinically improved with systemic steroid therapy and topical tacrolimus for two weeks. Relapses occurred after complete withdrawal of both treatments. After repeating the above therapy and applying topical tacrolimus as maintenance therapy, the condition was well controlled at the one-year follow-up. Discussion: EPDS is an uncommon inflammatory dermatosis with main incidence rate of elderly patients and female predominance. The diagnosis of EPDS cant be made only by histopathological examination, which is helpful for differential diagnosis. Microbiological investigations commonly remain negative. For the high risk of relapse, it is important for clinicians to be aware of maintenance treatment and a long- term management. Conclusion: It should be recognized by clinicians that EPDS is an uncommon and relapse disease, leading to serious cosmetic problems. The treatment lacks evidence-based medicine data, clinician should choose the appropriate therapy according to the condition of patients.

Treatment of erosive pustular dermatosis: a systematic review of the literature.

Erosive pustular dermatosis (EPD) is a rare chronic inflammatory condition of the scalp and legs that is often difficult to manage. Currently, there are no treatment guidelines. To systematically assess the existing literature on various treatment modalities and their efficacies when used in the management of EPD. We searched PubMed, Cochrane Libraries, Scopus, and clicnialtrial.gov databases for articles in the English language with no limited time frame. Emphasis was placed on articles that reported on treatment for EPD. Of the 168 articles identified by the literature search, 92 met eligibility criteria and were included for qualitative analysis. Efficacious topical treatments included clobetasol, betamethasone, and tacrolimus. Ninety-three and 88% of cases utilizing clobetasol and betamethasone respectively demonstrated improvement or resolution. All 32 cases utilizing tacrolimus reported improvement. Efficacious systemic treatments included oral steroids such as prednisone, methylprednisolone, and dexamethasone. Topical dapsone, photodynamic therapy, systemic steroids, cyclosporine, and oral zinc derivatives were also described with some success. According to available data, limited solely to case reports and case series, potent topical steroids are an effective treatment option for EPD. Topical tacrolimus may also be considered in cases that require long-term use or maintenance. Other treatment modalities shown to be successful based on high reported efficacy and low rates of recurrence after treatment include topical dapsone, systemic steroids, zinc derivatives, and cyclosporine. Further studies are needed to compare treatment modalities and to establish treatment protocols.

Erosive pustular dermatosis of the scalp following surgical procedures: a systematic review

Erosive pustular dermatosis of the scalp (EPDS) occurs in elderly individuals with significant actinic damage. EPDS also occurs in association with surgery; however, significant studies determining an association of EPDS with type of surgical closure is absent. This review examines whether the closure method following cutaneous surgery performed on the scalp is associated with development of EPDS. Databases were reviewed and studies describing EPDS after cutaneous surgery met inclusion criteria. Articles were excluded if EPDS developed after trauma or non-surgical procedures. Descriptive analyses were performed on the data. Thirteen case reports and 6 case series involving 32 patients met inclusion criteria. Fourteen articles (73.7%) stated that EPDS developed in the same location as, or near to, the closure site. Thirteen patients (40.6%) developed EPDS following skin grafting. Three patients (9.4%) developed EPDS following secondary intention healing, two patients (6.3%) following repair by primary intention, and one patient (3.1%) following repair with a local skin flap. Thirteen cases (40.6%) did not specify closure type. This review revealed that surgical procedures performed on the scalp utilizing skin grafts for closure may be increasingly associated with the development of EPDS compared to other closure types.

Erosive pustular dermatosis of the scalp

Erosive pustular dermatosis of the scalp (EPDS) is a rare inflammatory condition commonly associated with antecedent iatrogenic insult. EPDS may be diagnostically challenging owing to a lack of pathognomonic histologic findings and cutaneous manifestations that overlap with alternative dermatologic conditions. Therefore, EPDS may be more common than previously recognized. We present a 60-year-old woman with a four-year history of non-healing scalp erosions, progressive skin atrophy, and scarring alopecia despite intravenous antibiotics and intraoperative debridement who improved with systemic glucocorticoids. Our report emphasizes the importance of early recognition of EPDS when delayed wound healing and erosive disease occur in the setting of iatrogenic injury to the scalp. Timely treatment with systemic anti-inflammatory agents is paramount to prevent cicatricial alopecia and mitigate further scalp insult in EPDS.

Erosive pustular dermatosis of the scalp: challenges and solutions.

Erosive pustular dermatosis of the scalp is a rare chronic inflammatory disorder defined. It usually affects elderly people and is characterized by extensive pustular lesions, erosions, and crusts located on the scalp. The pathogenesis of this disease is not completely understood, but a known predisposing factor is skin trauma. Autoimmune disorders including rheumatoid arthritis, autoimmune hepatitis, Hashimoto thyroiditis, and Takayasu aortitis are associated diseases reported. The clinical examination reveals erythema, erosions, crusts, follicular pustules, and in advanced stages, scarring alopecia. A scalp biopsy is recommended but not specific, founding epidermal atrophy, focal erosions, and a mixed inflammatory infiltrate consisting of neutrophils, lymphocytes, and plasma cells. Bacterial cultures, fungal and viral stains are not necessary and are usually negative. . Topical high-potency corticosteroids, retinoids, calcipotriol, dapsone, and topical tacrolimus are reported treatments, while photodynamic therapy has been effective in some patients, but has induced the disease in others. All the findings are suggestive but not specific, so it is an excluding diagnosis. The combination of predisposing factors is very important for a correct diagnosis, such as elderly age, sun-damaged skin, presence of androgenetic alopecia, together with clinical manifestations, non-specific histology and laboratory investigations negative for other disease. In our opinion, this scalp disease is a challenge for the dermatologist. We review all the literature to better define the possible solutions in case of suspected erosive pustular dermatosis of the scalp.

Erosive pustular dermatosis of the scalp - an Australian perspective: Insights to aid clinical practice.

Erosive pustular dermatosis of the scalp has particular relevance in Australia, due to its association with actinic damage. Despite its rarity, the recalcitrant nature of erosive pustular dermatosis of the scalp dictates a protracted recovery fraught with relapse and recurrence, posing inherent challenges to successful treatment and complete recovery. In Australia, erosive pustular dermatosis of the scalp is prevalent in the elderly, who are negatively affected due to the condition. We propose a management outline to aid clinical practice, to improve the quality of life in the elderly, whilst providing insight into the current understanding and treatment of erosive pustular dermatosis of the scalp.

Erosive pustular dermatosis of the scalp: A neutrophilic folliculitis within the spectrum of neutrophilic dermatoses: A clinicopathologic study of 30 cases

It is general opinion that histopathology is nonspecific and of little value in diagnosing erosive pustular dermatosis of the scalp (EPDS). Clinicopathologic correlation of erosive pustular dermatosis of the scalp. We reviewed the clinical and pathologic records of patients with a clinicopathologic diagnosis of EPDS between 2011 and 2016 at the Dermatopathology Unit of Turin University. Thirty elderly patients with EPDS were identified (22 men and 8 women). Androgenetic alopecia was present in 19 of 30 patients. Triggering factors included mechanical trauma in 10 of 30 cases, surgical procedures in 4 of 30 cases, and herpes zoster in 1 of 30 cases. Three patients were affected by autoimmune disorders. The vertex was the most common location. Disease presentation varied markedly from tiny, erosive, scaly lesions to crusted and hemorrhagic plaques, mimicking pustular pyoderma gangrenosum. The pathologic changes differed according to lesion type and disease duration. Interestingly, a spongiotic and suppurative infundibulo-folliculitis was observed in 8 of 30 cases. This was a retrospective study. We believe that the primary lesion of erosive pustular dermatosis of the scalp is a spongiotic, pustular superficial folliculitis. The clinicopathologic similarities with other neutrophilic dermatoses, such as pustular pyoderma gangrenosum, suggest this condition should be included in this spectrum, where pathergy plays a pathogenetic role.
