Benign Fibrous Histiocytoma of Gingiva: A Rare Case Report.

Fibrous histiocytoma is a benign soft-tissue neoplasm that commonly involves the dermis. It is rare in the oral cavity. This lesion creates a diagnostic dilemma due to its nonspecific clinical appearance and microscopic similarities with other benign fibrous tissue lesions.

Angiogenesis and Fibrogenesis in Oral Submucous Fibrosis: A Viewpoint.

Unlabelled: Oral submucous fibrosis (OSF) is characterized by excessive fibrosis of submucosa. The degree of vascularity in OSF has always been a matter of debate. Angiogenesis is the key mechanism involved in regeneration and repair.

Pleomorphism of argyrophilic nucleolar organizer regions in oral submucous fibrosis and oral squamous cell carcinoma.

Background: Argyrophilic nucleolar organizer regions (AgNORs) is demonstrated to be useful in diagnostic pathology, mainly to distinguish benign lesions from their malignant counterparts. We aimed to correlate AgNORs pleomorphism with the severity of lesion in oral submucous fibrosis (OSMF) and oral squamous cell carcinoma (OSCC) using a retrospective study on 45 archival tissues.

Materials And Methods: Silver nitrate staining was performed on archival tissues consisting of 20 OSMF and 20 OSCC.
