Large lipoma of the larynx and its removal using a laryngofissure approach: Case report (original) (raw)

Lipomas of Larynx: The Rare Entities

International Journal of Phonosurgery & Laryngology, 2012

Lipoma is the commonest soft tissue tumor arising anywhere in the body, but its occurrence in the larynx is relatively rare. We present a rarest case of lipoma with cartilaginous metaplasia arising from the larynx just above the anterior commissure. The second case report is about a large spindle cell lipoma of larynx presented with stridor. How to cite this article Megalamani SB, Gadag R, Raza A, Satish A. Lipomas of Larynx: The Rare Entities.

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

Ear, nose, & throat journal, 2010

Lipomas are benign mesenchymal tumors that are often found intheheadand neck. Intrinsic lipomas ofthelarynx and supraglottic area are rare, as fewer than 115 cases havebeen reported in theliterature; almostallof these occurredin isolation. Wereport a case ofa laryngeal lipoma that wasassociated with diffusesystemic lipomatosis. The tumor was successfully removed via an endoscopic laser resection. To the best of our knowledge, this is only the secondcase oflaryngeal lipoma associated withlipomatosis to be reported in the English-language literature. Wealso review the literature on head and necklipomas.

Clinicopathological features of atypical lipomatous tumors of the laryngopharynx

Journal of Zhejiang University-science B, 2010

Atypical lipomatous tumor (ALT) of the laryngopharynx is rare. Here we report five cases to demonstrate their clinicopathological features. The patients were four males and one female, aged 41 to 69 years (median 53.6 years). All tumors (two in the hypopharynx and three in the larynx) presented as a slowly growing, painless mass. Symptoms included dysphagia (2/5), dysphonia (3/5), and the feeling of a foreign body in the throat (5/5). Tumors were well circumscribed or focally infiltrative, ranging from 2.0 to 5.0 cm (median, 3.4 cm) in size, and microscopically showed the typical features of lipoma-like ALT. Immunohistochemically, tumor cells were stained with S-100, vimentin, murine double minute 2 (MDM-2), and cyclin-dependent kinase 4 (CDK4). Two patients had local tumor recurrences at 6 and 14 months after initial surgery during follow-up. ALT of laryngopharynx is an indolent tumor. Immunohistochemical staining for MDM-2 and CDK4 is helpful in pathological diagnosis.

Retropharyngeal Space Lipomas. A Systematic Review of the Reported Cases in the Literature

Indian Journal of Otolaryngology and Head & Neck Surgery, 2021

Retropharyngeal space lipomas (RSLs) comprise a group of very uncommon head and neck benign, soft tissue tumors that originally grow in the retropharyngeal space. They can develop as individual tumors or in the context of syndromic lipomatosis. Symptoms usually arise as expanding RSLs exert pressure on adjacent structures, and clinical manifestations are often atypical and overlapping. Given the rarity of this diagnosis, current evidence is scarce, providing a rather fragmented picture. A literature search was conducted in all major medical databases, without time limitations. Tumors were considered RSLs if a benign lipomatous tumor appeared to develop originally in the retropharyngeal space. Cases with syndromic lipomatosis that demonstrated at least one such tumor involving the retropharyngeal space were included. A total of 52 publications concerning 79 eligible cases were found. Two of these cases concerned patients with Multiple Symmetrical Lipomatosis. A male predominance was found (61.5%, n = 48). Dysphagia (65.2%, n = 43) was by far the most common symptom, followed by snoring (37.9%, n = 25), dyspnoea (34.8%, n = 23) and dysphonia (30.3%, n = 20). The most used imaging modality was Computed Tomography (CT) (64.1%, n = 41). Surgery was the treatment in 73 cases (93.6%). The transcervical was the most selected approach (50.7%, n = 37), followed by the transoral approach (38.4%, n = 28). Complete recovery was reported, following treatment, in 60 cases (75.9%). Retropharyngeal space lipomas are benign tumors with a higher prevalence in male patients. Dysphagia is the most common symptom. Imaging is necessary for diagnosis, with CT scanning being usually sufficient as a single modality test. More than half of the patients in the literature are treated via an external approach. Diminishing of symptoms and full postoperative recovery is the most common outcome.

Giant buccal lipoma resected through transoral approach

Turkish Journal of Clinics and Laboratory, 2015

Lipomas are the most common benign soft tissue tumors, but they are rarely seen in the oral cavity comprising no more than 1 to 5% of all neoplasms. In the oral region, they are observed mostly in salivary glands, buccal region, floor of the mouth, tongue and lips which are generally well-defined, mobile, painless, slowly growing solitary or lobulated lesions. Lipomas in the buccal region and in the oral cavity may cause chewing, speech, and cosmetic problems. In most of the patients, they are diagnosed in early stages and rarely reach very big dimensions. Treatment of lipoma is performed via surgical excision by cutaneous or intraoral approach. Here with, we report a case of giant lipoma which was resected through transoral route.

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

Indian Journal of Otolaryngology and Head & Neck Surgery, 2020

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.

Oral lipoma of unusual size and location: a case report

Clinical and Laboratorial Research in Dentistry, 2015

A lipoma is a slow-growth benign tumor of the adipocytes. In the oral cavity, it is more commonly observed in the buccal mucosa; other sites less affected are the tongue, floor of the mouth, and lips. The objective of this report is to describe an extensive tumor affecting the dorsum of the tongue and the therapeutic maneuver performed. A 63-yearold man was referred to our clinic for evaluation of a tumor in the dorsum of the tongue with 6 months of duration. The physical examination revealed an extensive nodule, asymptomatic, submucosal, in the dorsum of the tongue at the left that measured approximately 4 cm. On palpation, the lesion was mobile and had rubbery consistency. According to these findings, the diagnostic hypotheses were lipoma and neurofibroma. Hence, surgical excision was performed and during the procedure a yellowish and well-delimited lesion was observed. The surgical specimen floated in 10% formalin. The histopathological examination confirmed the diagnosis of lipoma. The patient is asymptomatic after 40 months of follow-up. This report describes an unusual presentation of lipoma on the dorsum of the tongue and demonstrates that this lesion can reach large proportions. DESCRIPTORS | Lipoma; Tongue Diseases; Mouth Neoplasms; Tongue Neoplasms. RESUMO | Resumo Lipoma oral de tamanho e localização incomuns: relato de caso • Lipoma é um tumor benigno de crescimento lento dos adipócitos. Na cavidade oral, é mais comumente observado na mucosa jugal; outros sítios menos afetados são a língua, soalho oral e lábios. O objetivo deste relato é descrever um extenso tumor afetando o dorso da língua e a manobra terapêutica realizada. Um homem de 63 anos de idade foi encaminhado à nossa clínica para avaliação de um tumor no dorso da língua com 6 meses de duração. O exame físico revelou um nódulo extenso, assintomático, submucoso, no dorso da língua à esquerda, medindo aproximadamente 4 cm. À palpação, a lesão era móvel e tinha consistência borrachoide. De acordo com esses achados, as hipóteses diagnósticas foram lipoma e neurofibroma. Portanto, foi realizada excisão cirúrgica e, durante o procedimento, foi observada uma lesão amarelada e bem delimitada. O espécime cirúrgico flutuou em formalina a 10%. O exame histopatológico confirmou o diagnóstico de lipoma. O paciente encontra-se assintomático após 40 meses de acompanhamento. Este relato descreve uma apresentação incomum de lipoma no dorso da língua e demonstra que essa lesão pode atingir grandes proporções.

Unusual complications caused by lipoma of the tongue

Journal of the Korean Association of Oral and Maxillofacial Surgeons

Lipoma is the most common, benign, soft tissue, mesenchymal tumour and is composed of mature adipose tissue. It is infrequent in the oral cavity (approximately 0.3% of all tongue neoplasias). We describe the case of a 68-year-old man with a swelling at the tongue edge and tongue dysesthesia. Medical history, clinical assessment, radiographic images, and cytological analysis enabled specialists to classify this neoplasia as a lipoma. The patient recovered fully after surgical excision of the affected area, and the neuralgic symptoms regressed. Surgical excision is an elective treatment; however, accurate differential diagnosis, histological examination, and follow-up are required.

Lipomas of the head and neck: presentation variability and diagnostic work-up

The Journal of Laryngology & Otology, 2005

Introduction: Head and neck lipomas have seldom drawn attention in the literature, except in isolated case reports. Aims: This study aimed to assess the presentation variability of head and neck lipomas as well as the relative importance and efficiency of pre-operative diagnostic methods used. Materials and methods: A retrospective review was undertaken of medical records and imaging studies of 24 patients with histopathologically proven head and neck lipomas, over a three-year period. Results: The 24 patients had 26 lipomas. Men predominated (62.5 per cent). The posterior subcutaneous neck was the most common site. Three patients had deep lipomas affecting the hypopharynx, larynx and parotid gland; all were correctly diagnosed pre-operatively. Computed tomography (CT) scan with specific radiodensity recording was the preferred pre-operative investigation. Conclusions: Lipomas should be considered in the differential diagnosis of soft-tissue head and neck masses even in rare locations. A CT or magnetic resonance imaging scan can correctly diagnose a lipoma pre-operatively, thereby allowing better treatment planning.
