Malignant fibrous histiocytoma of the maxillary sinus. A case report.
We report a case of malignant fibrous histiocytoma of the left maxillary sinus in a 30 year-old man. The major problem encountered was the histological diagnosis of the first biopsy, which showed a non specific fasciculated, myxoid, alveolar pattern suggestive of a mesenchymal malignancy, thus preventing the correct diagnosis that became possible only when the surgical specimen was available.
