huge myxoid liposarcoma of the esophagus: a case report

although esophageal liposarcoma is an extremely rare tumor, liposarcoma is the most common soft tissue sarcoma in adults. liposarcoma is currently classified into the types of well-differentiated, myxoid, round cell, pleomorphic and dedifferentiated liposarcoma. up to now only a few cases of esophagus liposarcoma have been described in the world literature. we describe a myxoid type liposarcoma of the esophagus in a 68 year old man presented with hoarseness and intermittent dysphagea to solid food. he had a huge mass in his mouth which was mobile with gag reflex. a barium swallow, esophageal manometery and ct scan of the esophagus have not clearly revealed the mass. after endoscopic surgical resection of the tumor the histological examination revealed a myxoid liposarcoma. both the presenting signs and symptoms and the histology type are rare for such tumor. this case demonstrate a rare differential diagnosis of intermittent dysphagia as early diagnosis is so important in those tumors and should kept in mind them, although they are quite rare.
