Laryngeal lipoma:A Clinicopathologic Case Report

Lipomas are the most common benign soft tissue tumors. This tumor is not usual in the head and neck (less than 15% of all lipomas) and the intrinsic form of isolated laryngeal lipoma is quite rare. In literature only 17 cases were reported and classified as isolated true intrinsic laryngeal lipomas to this date. Grossly, lipomas consist of bright yellow fat. They appear smooth or lobulated, often well circumscribed or encapsulated, with yellowish-tan color. Microscopically, lipomas are composed of mature adipocytes which vary slightly in size and shape with a large central vacuole which often displace nucleus peripherally. Because isolated laryngeal lipoma symptoms are uncharacteristic and often has no systemic manifestation, clinical diagnosis is difficult. Treatment is based on complete excision of the tumor.We describe an extremely rare case of intrinsic laryngeal lipoma ,treated by excisional biopsy with success.
