Results: The study comprised 407 soft tissue tumors in total. Fibroblastic/myofibroblastic tumors constituted 9,1 % (37 cases) of these tumors. According to histopathology; 16 cases were categorized as fibromatosis, 8 cases as inflammatory myofibroblastic tumor, 6 cases as infantile fibrous hamartoma, 3 cases as nodular fasciitis and 2 cases as infantile myofibroblastic tumor/myofibromatosis an...

INTRODUCTION Solitary fibrous tumors of the pleura (SFTP) are primary tumors arising from mesenchymal cells. Immunohistochemical studies have demonstrated that the origin of these tumors is mesenchymal rather than mesothelial. The aim of this study is to present our experience with diagnosing and treating patients with SFTP. MATERIAL AND METHODS We analyzed 18 patients treated at the Departme...

Spectrum of Fibroblastic and Myofibroblastic Tumors When one considers soft tissue tumors in pediatrics, tumors of vascular (29%), neurogenic (15%), and myogenic (striated muscle, 14%) origin occur more often than fibroblastic-myofibroblastic tumors (12%). The spectrum of fibroblastic/myofibroblastic tumors is quite divergent from both clinical and histopathologic viewpoints (Table 1). These tu...

Primary benign fibrous histiocytoma involving the central nervous system is an exceedingly rare tumor with most cases originating from the dura or parenchymal tissue. Diagnosis of primary benign fibrous histiocytoma is difficult due to its confusing histopathological characteristics. Two cases of primary intracranial benign fibrous histiocytoma mimicking parasagittal meningioma are presented in...

PURPOSE 92 kDa matrix metalloproteinase-9 (MMP-9) is believed to play an important role in degrading the matrix and basement membrane, contributing to the invasion and metastasis of malignant solid tumors. However, little is known about its involvement in a malignant fibrous histiocytoma. The aim of this study was to investigate the expression of MMP-9 and to correlate its expression with clini...

Introduction  Benign fibrous histiocytomas are common lesions of the skin that rarely affect the tongue. Such cases are available in the literature exclusively as case reports. Similarly, malignant fibrous histiocytoma, now classified as undifferentiated pleomorphic sarcoma, is exceedingly rare in the tongue and not fully understood. Objectives  This study systematically reviews the available l...
