Malignant fibrous histiocytoma (MFH) is a rare primary neoplasm that constitutes less than 1% of the malignant tumors of bone, and involvement of the skull is very rare. We present a case of malignant fibrous histiocytoma of the skull, presenting an intraosseous lesion in a 43-yr-old woman. She had a rapidly growing, tender mass in the right parietal region. A plain radiograph showed an osteoly...

Malignant fibrous histiocytoma (MFH) is the most common fibroblastic tumor, but its cutaneous metastasis, especially in-transit metastasis, is extremely rare. We describe the case of a 30-year-old Japanese man with a recurrent MFH on the scalp accompanied by in-transit metastasis, which had been treated as a benign skin tumor 8 years before. The main bulk of the recurrent tumor was located in t...

Malignant fibrous histiocytoma (MFH) is the most common soft-tissue sarcoma, but is relatively uncommon in head and neck area. Histologically, it is difficult to distinguish this tumor from other sarcomas and carcinomas. Surgery is the most reliable treatment for MFH, but the 5-year survival rate for cases of this tumor in the head and neck is low in comparison with MFH of the extremities and t...

BACKGROUND Bevacizumab is a specific inhibitor of angiogenesis and a neutralising antibody against vascular endothelial growth factor (VEGF). The effect of bevacizumab was evaluated on malignant fibrous histiocytoma (MFH) in vivo using an animal model. MATERIALS AND METHODS MFH cell line, NaraH, was implanted to athymic nude mice which were randomly divided into a treatment and a control grou...

Malignant fibrous histiocytoma (MFH) of the gastrointestinal tract is extremely rare. Here we report a case of MFH of the cecum and review other cases of large bowel MFH in the literature. A 64-year-old man had a large tumor mass in the cecum associated with multiple small peritoneal implants. Histologically, most of the lesion showed inflammatory pseudotumor-like appearance; that is, a mixed p...

Simultaneous multiple malignancies of the larynx are rarely reported. In this study, we describe a case with simultaneous laryngeal, moderately differentiated squamous cell carcinoma (SCC) and primary malignant fibrous histiocytoma (MFH) in a patient presenting with progressive hoarseness and without cervical lymphadenopathy. The clinical presenta...

Introduction Malignant fibrous histiocytoma(MFH) is clinically most frequently diagnosed in adult’s soft tissue sarcoma. And not only in soft tissue but also rarely in the bone or organ parenchyma that’s ocurrece has been reported. But because of treatments such as chemotherapies for MFH shows little effect so far, MFH’s prognosis has still not getting remarkable improvement. And it’s pivotal p...

Using gene microarray expression profiling, we previously found that apolipoprotein D (Apo D) was highly expressed in dermatofibrosarcoma protuberans (DFSP). In this study, we confirm that Apo D is highly and relatively specifically expressed in DFSP using immunohistochemistry. A tissue microarray containing 421 soft tissue tumors was constructed and stained with antibodies against Apo D and CD...

MALIGNANT FIBROUS HISTIOCYTOMA (MFH) IS A FAIRLY COMMON TUMOR IN THE DEEP SOFT TISSUES: the most frequent primary sites are the lower (49%) and upper (19%) limbs, but it has been reported even in the retroperitoneum and abdomen (16%), while localization in the breast is extremely rare (1-2). Breast cancer is rarely seen in males, accounts for approximately 1% of all breast cancer, and the breas...
