PATIENT HISTORY:
The patient is a 65 year old man with a history of hypertension and valvular heart disease who presented with spontaneous hemorrhage of the right lower extremity soft tissue. He had neither constitutional nor ocular symptoms and no evidence of muscular weakness. A chest x-ray showed an anterior mediastinal mass confirmed by CT scan. The mass was contiguous with the inferior thymus. CT-guided biopsy of the mass was performed and cytologic analysis of the aspirate showed keratin- and vimentin-positive spindle cells. The anterior mediastinal mass was surgically resected
