Laryngeal lipoma: a rare cause of dysphonia

Abstract

Lipomas are the most common mesenchymal tumors. Laryngeal lipomas represent 1% of all lipomas but unlike other locations may cause life-threatening symptoms by obstruction of the respiratory tract. In this study, the case of a 32-year old woman with laryngeal lipoma is discussed. The lesion was detected on the left aryepiglottic fold, presented as a stalked and dynamic mass of 2 centimeters diameter. The imaging aspects of laryngeal lipoma cases, clinical evaluation, and approaches to treatment will be discussed.

Laryngeal infiltrative lipoma in a nine‐year‐old Rottweiler

“…In this report, the mass was diagnosed in a senior (nine years old) large breed (Rottweiler) female dog, which correlates with the prevalence noted in the literature review. Contrarily to these observations, laryngeal lipoma in human medicine affects mostly middle‐aged men and are rarely infiltrative 15…”

“…It differs from lipomas in their biological behaviour, as infiltrative lipomas are more aggressive and potentially have a high recurrence rate 1–3. CT is a useful tool to differentiate different types of tissues (adipose < −20 Hounsfield units (HU)) and for surgical planning 9–15…”

Lipomas of head and neck

“…They cause functional deficits like dysphagia, neck pain and obstructive sleep apnoea. 7 There have been reports of deep intra muscular lipoma in the submandibular region by Adachi etal. 8 Pusiol etal reported an oncocytic sialolipoma of submandibular gland.…”

“…8 Pusiol etal reported an oncocytic sialolipoma of submandibular gland. 7 Gultekin et al reported a case of parosteal lipoma. 9 Furlong etal in their study reported that lipomas in the head and neck are common in the parotid region followed by buccal mucosa and lip.…”

Lipoma laríngeo en repliegue aritenoepiglótico: reporte de caso.

“…Su tamaño inicialmente puede ser tan pequeño pudiendo ser imperceptible, pero a medida que avanza el tiempo tiene un crecimiento que se da lentamente y que de forma progresiva empieza a causar los síntomas (4). Tiende a ubicarse en zonas donde existe grasa subcutánea, en la laringe se encuentra principalmente en el repliegue aritenoepiglotico y el espacio pre-epiglótico (5). En el caso de los lipomas extrínsecos que infiltran otras áreas distintas a las de su origen, se debe prestar gran atención en el diagnóstico ya que podría corresponder a un liposarcoma.…”
