Malignant Fibrous Histiocytoma Arising from Nasal Cavity

Pure sarcomatoid carcinoma of maxillary sinus and nasal cavity simulating malignant fibrous histiocytoma.

Although a few cases of sinonasal carcinoma with focal sarcomatous differentiation have been reported, pure sarcomatoid carcinoma has not been reported in the English literature. Imaging studies and gross inspection in a 60-year-old man with left-sided face pain revealed a mass in the left maxillary sinus and nasal cavity. A large incisional biopsy specimen from the nasal cavity revealed prolif...

Giant malignant fibrous histiocytoma of the pleura arising from solitary fibrous tumour.

A 61 year old man was admitted with acute breathlessness. A computed tomographic (CT) scan showed a pleural mass 20 cm in diameter occupying the whole right hemithorax and causing massive lung atelectasis, with the exception of a small part of the upper lobe (fig 1A). Magnetic resonance imaging (MRI) showed a right pleural effusion with right hemidiaphragm and liver lowering without infiltratio...

Malignant fibrous histiocytoma.

Calvarial malignant fibrous histiocytoma.

Primary malignant fibrous histiocytoma (MFH) of the central nervous system (CNS) is uncommon. We report cases of two young patients of MFH arising from the cranial meninges and involving the adjacent skull and scalp. There was infiltration of the brain in one case. Both the lesions were excised and primary scalp repair was performed.

Liposarcoma of pleural cavity with recurrence as malignant fibrous histiocytoma.

The case of a 54-year-old male, with a massive right pleural liposarcoma weighing over 3200 g, is presented. The tumor was found by light and electron microscopy to be of well-differentiated and pleomorphic subtypes, and it apparently represents the sixth reported case of liposarcoma primary to the pleura. Two years after excision of the primary tumor, it recurred as a neoplasm with histologic ...
