Pharyngeal stromal tumor
PHARYNGEAL STROMAL TUMOR
Figure 1. Endoscopic view of pharyngeal stromal tumor. Epiglottis is at top of figure.
Figure 2. Photomicrograph of unclassified benign fibromyxoid lipomatous tumor (H&E, orig. mag. ×100).
A 63-year-old Asian-American man presented with a chief complaint of dysphagia to solids and liquids as well as shortness of breath and a choking sensation. Although his symptoms had progressed insidiously over the previous 6 months, he denied food impaction, weight loss, or aspiration. He complained of daily nocturnal heartburn. His medical history was remarkable for a cervical esophageal leiomyoma that was removed 6 years before. Endoscopy showed a large submucosal mass in the pharynx (Fig. 1) and short segment Barrett’s esophagus. The biopsy of the pharyngeal mass showed a probable liposarcoma, and the patient underwent
partial pharyngectomy, total laryngectomy, and a modified neck dissection at the same hospital where he underwent resection of the esophageal leiomyoma. His dysphagia resolved after surgery and he recovered uneventfully. Histologic examination (Fig. 2) showed the pharyngeal tumor to be similar to the previously removed esophageal leiomyoma. The final pathologic diagnosis was unclassified benign fibromyxoid lipomatous tumor.
