Laminin matrix formation and S-100 protein and/or desmin-positive cells in malignant fibrous histiocytoma (MFH).

چکیده
16/30 human storiform-pleomorphic malignant fibrous histiocytomas (MFH) showed a focal pericellular immunostaining for laminin. 14/16 of these laminin-positive tumours additionally revealed an atypical cellular differentiation (desmin- and/or S-100 protein-positive cells). The significance of focal laminin positivity along with atypical, non-entity specific differentiated cells is discussed before the background of laminin as being an indicator and promoter of differentiation in MFH. The limited value of a laminin detection in MFH for solving differential diagnostic questions (MFH versus other poorly differentiated sarcomas with basement membrane formation) has been pointed out.

BACKGROUND/AIMS Malignant fibrous histiocytoma (MFH) of bone, a relatively rare primary malignant bone tumour, is a distinct clinicopathological entity as opposed to MFH derived from soft tissue. Although the true histogenesis of this condition is still controversial, a considerable number of cases of MFH in soft tissue show positive immunohistochemical reactivity for muscle markers such as des...

Introduction: Myxofibrosarcoma was originally described as the myxoid variant of Malignant Fibrous Histiocytoma (MFH), a high-grade and aggressive sarcoma, which is very uncommon in the head and neck region, with about 100 cases reported up to now. MFH occurring in the maxillary sinus is so rare that only 23 cases have been reported. We hereby report a case of myxofibrosarcoma in the maxillar...
متن کاملMetachronous Malignant Fibrous Histiocytoma- A Rare Case Report
Malignant fibrous histiocytoma (MFH) is one of the most common types of soft tissue sarcomas in adults. Distant metastases are developed in 30–40% of patients with MFH, with the most common site being the lung. However, metachronous MFH has not been reported previously in literature. This report describes a case of a 30-year-old man, who had two metachronous thigh tumors, both of which were con...

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...
