Retrospective analysis of radiological investigation of surgically excised head and neck lipomas

PurposeDifferentiating benign lipomas from malignant causes is challenging and preoperative investigative guidelines are not well-defined. The purpose of this study was to retrospectively identify cases of head and neck lipomas that were surgically resected over a 5-year period and to identify the radiological modality chosen and features discussed in the final report. Multidisciplinary outcomes and pathology reports were examined with a view to identifying high risk features of a lipoma to aid in future risk stratification.MethodsRetrospective chart review of pathology characteristics, radiological features (modality, size, calcifications, septations, globular/nodular foci), multidisciplinary discussion and history of presenting complaint was performed.ResultsTwo liposarcomas and 138 lipomas were identified. Twenty-two percent of all lipomas received radiological investigation. Twenty-two percent of imaging referrals were possibly inappropriate. Furthermore, radiological features suggestive of malignancy were not present in the final radiology report, X2 = 28.8, p < 0.0001.ConclusionAs expected, the incidence of liposarcoma is low. There is limited awareness of radiology referral guidelines superimposed with a tendency to over-investigate lipomas. Furthermore, radiological features suggestive of malignancy were inconsistently reported on and not documented in multidisciplinary discussions. Therefore, we propose a multidisciplinary checklist for referring physicians and radiologists to aid in diagnostic work-up.

Giant Lipoma of Neck: Case Report and Literature Review

Giant Lipoma of Neck: Case Report and Literature Review

Giant anterior triangle neck lipoma with unusual extension: a case report

BackgroundLipomas are considered to be the most common benign mesenchymal neoplasm which can originate from any fatty tissue. Only 13% of lipomas are present in the head and neck region where the posterior triangle of the neck is the most common site.Case presentationGiant lipomas > 10 cm involving the anterior triangle of the neck with para- and retropharyngeal extension are rarely seen. We report a 59-year-old male patient with giant anterior neck space lipoma 13 × 7.5 × 3.5 cm with medial extension to the retropharyngeal space which was surgically excised.ConclusionsGiant anterior neck lipomas are very challenging in excision compared to posterior neck ones. ENT surgeons should keep lipomas in mind when dealing with anterior neck lesions. Complete surgical excision is the best treatment modality.Level of evidence4

A 14-year retrospective study focusing on clinical and morphological features of oral cavity lipomas: A review of main topics

BackgroundLipomas are benign soft tissue neoplasms frequently found in the human body. Head and neck lipomas are relatively uncommon, accounting for 1 to 4% of benign lesions at this location. This 14-year retrospective study analyzed the clinical-pathological features of cases of oral cavity lipomas and their histopathological variants seen at a single oral pathology referral center. Material and methodsData on age, sex, anatomical location, clinical diagnosis, and histological subtypes were collected from all cases microscopically diagnosed as lipoma. Three previously trained oral pathologists re-evaluated hematoxylin/eosin-stained slides of all selected cases. ResultsAmong 7,861 oral and maxillofacial lesions diagnosed at the service, 95 (1.2%) were lipomas or their histopathological variants. There was a predominance of female patients (n = 65; 68%); the mean age at diagnosis was 58.8 years (±13.56). We found the following histological subtypes: conventional lipoma, fibrolipoma, spindle cell lipoma, sialolipoma, osteolipoma, chondrolipoma, and intramuscular lipoma. The buccal mucosa was the most affected site. Conventional lipoma and fibrolipoma were the most commonly diagnosed histological variants. Although most lipomas are asymptomatic, large lipomas can occur, reaching a diameter of 4 cm. ConclusionThe present study reinforces the importance of careful clinical and histopathological examination in order to obtain an accurate diagnosis and to ensure appropriate treatment.

A traumatic injury leading the lipoma of neck: a rare image.

A 58 years old male visited our hospital with the complaint of swelling over the posterior aspect of the neck after sustaining a trauma as a result of a fall of a cement slab over him 5 years back. The patient is under a combination of metoprolol and telmisartan medication for the rectification of hypertension for 10 years. The patient got admitted to the hospital for the above complaint and has undergone a histopathology report, MRI, and USG investigation. In the histopathology report, we received a single container labelled as a resected specimen of large lipoma. On the cut section, a solid, yellowish, homogenous area was identified. MRI investigation reported a lesion over the nape of the neck size measuring from 25x20x8cm in size. USG report stated a lesion over the nape of the neck and occipital region with the dimensions of the left side as 53x25mm approximately, right side as 58x31.5Â mm approximately. After both MRI and USG investigation, the patient was diagnosed with lipoma over the nape of the neck and occipital region. The patient had gone through two separate operations in a spare of 11 days. Complete excision of Excessive fibrofatty tissue size 10x15 cm lipoma was done. Flap was approximated and romovac drian no 14 placed. Closure was done with ethilon2-0 ac. PPd debridement was done with secondary suturing. Hemostasis was confirmed and Patient stable. Shifted to ward and got discharged after 1 week with prescribed medications and physiotherapy exercise.

A Large Lipoma of Neck

A 30 year-old female presented with a gradually increasing painless swelling in the back of the neck, growing since the last two years. The swelling was about 2 cm in size when first noticed, which gradually increased to its present size (Figure 1). Examination revealed a large, soft, globular swelling in the back of the nape of the neck. Surface was lobulated and the margins were rounded, well defined and slipped under the finger.

HISTOPATHOLOGICAL ASPECTS OF ORAL CAVITY FIBROLIPOMA: A CASE REPORT

Fibrolipoma is an unusual histologic variant of classical lipoma, in which neoplastic adipose cells are incorporated together with dense collagen, representing 1.6% of head and neck lipomas. The most common occurrence area of fibrolipoma is the buccal mucosa followed by the tongue. Histologically it is composed of mature adipose cells subdivided into lobes surrounded by dense connective tissue, which is what differentiates it from classic lipoma. It is reported a 68-year-old male, who presented a soft, oval, pediculated nodule with a smooth surface and painless located on the left upper lip mucosa measuring 0.9 x 0.6 cm with 4 months of evolution. Excisional biopsy was performed and the histopathological sections revealed neoplastic formation with presence of mature adipocytes and bundles of dense collagen, compatible with oral fibrolipoma without malignant characteristics. The case illustrates a rare entity of the oral cavity and the aspects with the literature are discussed.

A case report of giant anterior neck lipoma

&lt;p class="abstract"&gt;Lipoma is a benign mesenchymal tumor with a thirteen percent incidence in head and neck region. Posterior triangle is the most common location while anterior neck lipoma is a rare one. Giant lipomas &amp;gt;10 cm have been reported in different parts of the body but rarely in the anterior neck. Surgical excision remains the treatment of choice. We here report a case of giant anterior neck lipoma in a 50 year old male managed surgically.&lt;/p&gt;

Head and Neck Lipomas at Uncommon Subsites: A Series of Four Cases.

Lipomas are benign soft tissue tumors; the most common ones present in subcutaneous planes distributed throughout the body. However, there are few sites which are unusual location for lipomas. Here, we discuss the presentation of 4 cases of head and neck lipomas at unusual subsites. Though its prevalence is high in the body, lipomas are rarely seen in upper aerodigestive tract and these lesions can cause severe deglutition and respiratory distress problems in addition to cosmetic deformities. In the head and neck, most common location of lipoma is the cheek, followed by the tongue. Tonsillar lipomas are very rare. The mainstay treatment for lipomas is complete surgical excision and recurrence following complete removal is rarely known. We are here discussing a series of 4 cases of lipomas, presenting at uncommon subsites in head and neck region. These include lesions over neck, tongue, palate and tonsillar fossa. Lipomas are benign mesenchymal tumors, that are initially non bothersome. However, with increasing size they can cause severe aerodigestive problems with functional compromise and need complete surgical excision.

From head and neck lipoma to liposarcoma: a wide spectrum of differential diagnoses and their therapeutic implications.

To overview the array of differential diagnoses among lipomatous tumours of the head and neck with special focus on their evaluation, three-dimensional assessment, and their available treatments. The head and neck is an infrequent localization for lipomatous tumours, even though they represent the most common mesenchymal lesions. Lipoma, spindle cell/pleomorphic lipoma (SC/PL), atypical lipomatous tumour/well differentiated liposarcoma (ALT/WDLPS), de-differentiated liposarcoma (DDLPS), myxoid liposarcoma (MLPS), and pleomorphic liposarcoma (PLPS) are the most distinctive histotypes. Lipoma and SC/PL present alterations of chromosomes 12 and 13, ALT/WDLPS and DDLPS both show the Mouse Double Minute 2 amplification, whereas MLPS presents a CHOP gene fusion. Diagnosis of PLPS is purely morphological as there is no pathognomonic genetic alteration identified to date. Radiological assessment can be challenging for the presence of nonadipose components within the lesion. Surgery is the mainstay of treatment, even though achieving true radicality in terms of a large cuff of healthy tissue surrounding the tumour is not always realistic in the head and neck. Adjuvant radiation, eventually in combination with systemic chemotherapy, has been shown to improve overall survival in patients with positive margins, high-grade, deep, and more than 5 cm lesions. Further studies should be aimed at the evaluation of the role of hadron therapy, as well as targeted drugs against overexpressed proteins. Adequate differential diagnosis of the histotypes collected under the umbrella term of head and neck lipomatous tumours plays a fundamental role in treatment and follow-up of these lesions and requires specific expertise with referral to high-volume centres.

English

Lipomas are common benign soft tissue tumors, with 15 to 20% of the cases affecting the head and neck region and 1 to 4% involving the oral cavity. The literature has many reported cases of head and neck lipoma but few comprehensive studies hence, the aim of this study was to review and analyze the clinical and histopathologic features of head and neck lipomas in Nigerians. A fifteen-year retrospective study evaluated thirty-six cases of head and neck lipomas among Nigerians. Head and neck lipomas constituted about one-tenth (9.4%) of the total body lipomas seen over the study period. The peak age incidence was fifth decade of life and most (58.3%) of these patients were older than 40 years. There was male gender predilection with male to female ratio of 1.4:1. The most common site of occurrence was forehead (41.7%), followed by scalp and cheek (16.7% each). Lipomas were seen in two intraoral locations (lip and tongue) and these accounted for 13.9% of the head and neck lipomas and 1.3% of lipomas in the whole body. The average size of the lesion was 3.3 cm. Head and neck lipomas are fairly common among Nigerians who are more than 40 years of age. While the conventional and fibrolipoma were the two histologic variants recorded, complete surgical excision of the lesion offered satisfactory treatment outcome. Key words: Head and neck, lipoma.

Symptomatic head and neck lipomas

IntroductionLipomas are very common benign lumps that could be encountered in any part of the body but with limited proportion being present in the head and neck region. Case summaryIn this article, three different cases of symptomatic cervical lipomas were illustrated, with their different diagnostic as well as therapeutic approaches and will be discussed in light of medical literature. DiscussionThese cervical tumors tend to grow slowly giving variable signs that include dysphagia, dyspnea, dysphonia due to the mass effect of surrounding structures or can be present as simple as a cosmetic concern. Clinicians must bear in mind the malignant transformation of lipomas, which can be challenging to diagnose. With this article, authors will try to highlight the importance of maintaining a good communication between surgeons, pathologists and radiologists as an essential part of the medical management.

Giant Lipoma of the Head and Neck Region: Case Report and Review of the Literature

Head and neck lipomas are fairly common but their presentation in areas like submandibular, submental and sublingual regions are rarely seen. Lipomas are generally asymptomatic and gradually progressive in size, causing aesthetic and functional deficits. Surgical excision remains the mainstay of treatment. Radiological investigations like CECT and MRI play a critical role in diagnosis and management of these lesions. We describe a case of a giant lipoma involving the sublingual, submandibular and submental region, and its management.

Giant Lipoma of the Neck: A Case Report

Lipomas are benign mesenchymal tumours, which are composed of the fat cells of adult type. Lipomas have been identified in all age groups, but they are mostly seen between 40 and 60 years of age. They are usually solitary tumours, more common in females, most often located on the posterior neck and on the back, but they can also be multiple and small tumours all over the body and extremities. Anterior neck lipomas are rare. We report a case of a giant subcutaneous solitary lipoma of anterior neck in a 60-year-old male managed surgically.

Anterior Neck Lipoma with Anterior Mediastinal Extention – A Rare Case Report

Lipomas are the most common benign mesenchymal tumour. Thirteen percent of lipomas are seen in head and neck region. Anterior neck lipoma is a rare one. Anterior neck lipoma with mediastinal extension is extremely rare. We are presenting a case of 52 years old male reported to Central Referral Hospital, Sikkim Manipal Institute of Medical Sciences, Gangtok, Sikkim with complains of swelling in left side of neck for last 18 months along with occasional history of dyspnoea. Physical examination, ultrasound, computed tomography and fine needle aspiration cytology are in favor of lipoma. Due to its location up to the anterior mediastinum, the surgery could not be done in this hospital and patient was referred to higher center having cardiothoracic surgical back up.

Infiltrating lipoma of neck

Lipomas are common benign soft tissue neoplasms of mature adipose tissue. The peak incidence is usually in the fifth or sixth decade of life, while occurrence in children is very uncommo. Multiple presentations may occur in about 5% patients. The tumors may or encapsulated may not be. In a review of more than 1000 benign tumors of adipose tissue, over 80% were ordinary lipomas; nearly all the others were angiolipomas, intramuscular lipomas, or lipoblastomas. Other types accounted for less than 2% of all benign lipomatous neoplasms. The occurrence in the head and neck is relatively rare. Only 25% lipomas arise from the head and neck. Lipomas of the anterior neck are extremely rare. They may extend posteriomedially between the sternocleidomastoid and digastric muscles. Most commonly, they arise at the posterior subcutaneous neck. The deep lipoma is usually larger and deforms the surrounding tissue as compared to superficial lipomas which are generally more circumscribed.

A case of lipoma of lateral anterior neck treated with surgical enucleation.

Lipoma arise in almost 50% of all soft tumours. The neck lipomas are rare tumours that may present as painless masses with slow growth, in the lateral portions of the neck. Some lipomas, such as the one studied in our case, grow deep in the subcutaneous tissue, in close contact with muscles. Here, we report a case of lipoma extending from pre-tragal region up to the ascending branch of the mandible in a 62 year old man, treated with enucleation. The inferior margin of lipoma involved the pharyngeal and the superior margin was achieved by the top of the skull base. The mass of lipoma caused breathing difficulties in the patient, preventing regular sleep. No complication was recorded in the post-operative period and no further surgery was performed. The complete resolution after one year's follow-up, together with the rarity of the anatomical site, makes this case worthy of description. A correct diagnosis facilitated removal of this lesion with a surgical method.

Laryngeal Lipoma Associated with Diffuse Lipomatosis: Case Report and Literature Review

Lipomas are benign mesenchymal tumors that are often found in the head and neck. Intrinsic lipomas of the larynx and supraglottic area are rare, as fewer than 115 cases have been reported in the literature; almost all of these occurred in isolation. We report a case of a laryngeal lipoma that was associated with diffuse systemic lipomatosis. The tumor was successfully removed via an endoscopic laser resection. To the best of our knowledge, this is only the second case of laryngeal lipoma associated with lipomatosis to be reported in the English-language literature. We also review the literature on head and neck lipomas.
