A case of pleomorphic lipoma of the hypopharynx.

We report the first case of pleomorphic lipoma in the hypopharynx. A 69-year-old man was admitted because of a 12 year history of dysphagia and cough. Direct laryngo-pharyngoscopy revealed a polypoid, yellow, smooth, submucosal tumor with well defined borders. At CT scan the tumor showed a hypodense pattern and measured 3 cm. Microscopically the neoplasm was composed mainly by typical lipomatous tissue, bundles of collagen and pleomorphic multinucleated cells, some with floret-like appearance. Lipoblasts and mitoses were not found. Six months after resection there was no evidence of recurrence.
