A Case of Hypopharyngeal Leiomyosarcoma

Squamous cell carcinoma is the most common malignant neoplasm in the hypopharynx. Other types of malignant neoplasm are rare. Leiomyosarcomas are commonly found in the alimentary tract and the uterus. Only 6 cases of hypopharyngeal leiomyosarcoma have been reported in the past. We report here the seventh case of this rare tumor, which arose from the piriform sinus in a 69-year-old man. The tumor was completely resected, and the pharynx and larynx were reconstructed. The patient remains free of recurrence 25 months postoperatively.
