[Synchronous malignant fibrous histiocytomas in ileal and atrial locations].
Diagnosis of malignant fibrous histiocytoma in ileal and atrial locations is uncommon and diagnosis of synchronous lesions in both locations is exceptional. We present the case of a 60-year-old woman with a malignant fibrous histiocytoma in both locations. Malignant fibrous histiocytoma is an aggressive neoplasm. Definitive diagnosis is histological. Immunochemistry helps to establish the differential diagnosis with other entities.
