Solitary Sinonasal Fibrous Tumour: A Rare Presentation And Pathology

Solitary Fibrous tumour represents a spectrum of mesenchymal tumors, encompassing tumors previously termed as hemangiopericytomas. They are vascular neoplasms of outer wall pericytes of Zimmermann's capillaries. These tumors presumed to be of fibroblastic differentiation, seen most commonly in adults and can occur at any site. We report the case of a young adult male presenting with a swelling over medial canthus of left eye with a discharging sinus. Wide local excision was done and the diagnosis was confirmed by biopsy and immunohistochemistry.
