We report an example of an esophageal giant fibrovascular polyp harboring a well-differentiated liposarcoma with rhabdomyomatous differentiation in a 68 year-old man. Initial imaging studies including fiberoptic endoscopy and 2 computed tomographic examinations, and laparoscopic myotomy failed to demonstrate the polypoid intraluminal nature of the lesion. Thus, alternative diagnoses including a malignant neoplasm and achalasia were entertained. A third computed tomography with contrast showed a pedunculated mass. Surgical resection revealed a 15-cm smooth-surfaced club-shaped mass composed of a well-differentiated liposarcoma demonstrating myoglobin, muscle-specific actin, and myogenin-positive rhabdomyomatous differentiation. To date, no previously reported giant fibrovascular polyp case has described a liposarcoma with rhabdomyomatous change.
