Synchronous double cancers of the hypopharynx: malignant fibrous histiocytoma and squamous cell carcinoma.

We report a unique case of synchronous double hypopharyngeal tumors in a 39-year-old man. The patient presented with a 1-year history of a muffled voice and mild odynophagia. Laryngoscopy detected two grossly different tumors in the hypopharynx: a malignant fibrous histiocytoma (MFH) in the postcricoid area and a squamous cell carcinoma (SCC) in the posterior pharyngeal wall. Chemoradiotherapy was administered, and the patient was free of disease at 23 months of follow-up. Synchronous double cancers of the hypopharynx that feature different oncotypes are very rare, especially those that include an MFH. In fact, to the best of our knowledge, no case of synchronous MFH and SCC of the hypopharynx has been previously reported in the literature. Because the number of reported cases of MFH in the hypopharynx is so small, no consensus exists with respect to the preferred option among the various treatment choices.
