Esophageal spindle cell lipoma.

Symptomatic ordinary esophageal lipomas are rare tumors. Spindle cell lipomas (SCLs) of this location are even more infrequent. To our knowledge, only a previous esophageal SCL case has been reported. We describe herein the case of a 62-year-old woman with a long history of heartburn and feeling of abdominal distension. Preoperative investigations, including a Barium meal, gastroscopy, and echoendoscopy revealed a lipomatous polypoid mass attached to the middle esophageal segment. The lesion (3.5×2×1 cm) was excised endoscopically under deep sedation. The final histopathology diagnosis was pedunculated SCL. An accurate diagnosis of esophageal SCL is crucial to rule out malignant lesions, relieve symptoms, and undertake suitable treatment. The main differential diagnosis includes well-differentiated sclerosing liposarcoma, atypical spindle cell∕pleomorphic lipomatous tumor, giant fibrovascular polyp, and fat-forming solitary fibrous tumor. Although rare, SCL should be added to the list of lipomatous tumors that can affect the esophagus. Complete excision is the appropriate treatment.
