Primary intra-abdominal malignant mesenchymal tumours are very rare and there are not many cases of visceral malignant fibrous histiocytoma in the English literature. We report a new case of abdominal malignant fibrous histiocytoma presenting as abdominal pain and pyrexia of unknown origin in a 54 year old female followed by a brief review of literature. Presentation with pyrexia of unknown ori...

Primary intraabdominal malignant mesenchymal tumors are very rare. There are just few cases of intraabdominal visceral malignant fibrous histiocytoma in the literature. We report a case of primary malignant fibrous histiocytoma of the spleen in a 57-year-old man, with a recurrence eight years after the splenectomy. After the initial surgery the patient was without complaints, and refused to rec...

Three fibrous histiocytomas, primary in skin, were studied by light and electron microscopy and by frozen section histochemistry. The term malignant was applied to cutaneous tumors which demonstrated aggressive multinodular local growth, including angioinvasion and/or extension into bone, muscle, and fascia. Metastases were not found. Strongly positive reactions for hydrolytic enzymes, particul...

Malignant fibrous histiocytoma is one of the most common sarcomas that occur in soft tissue, it usually develops in old age individuals and the incidence is similar between the genders. We report here on a case with invasive local recurrence after surgical resection of a malignant fibrous histiocytoma that occurred in the left psoas muscle of a 69-year-old male patient. The patient was first ad...

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.

We report a case of malignant fibrous histiocytoma arising from the renal capsule. The tumor was found during screening ultrasonography. Surgical excision and adjuvant chemotherapy consisting of cyclophosphamide, vincristine, adriamycin and actinomycin D were performed. There has been no recurrence as of 2 years and 4 months after the operation. We reviewed the 5 other cases of malignant fibrou...
