Atypical Oral Fibrous Histiocytoma - An Uncommon Histiocytic Lesion Presenting as Inflammatory Fibrous Hyperplasia

Abstract

Fibrous histiocytoma, as the name suggests, is a lesion which is prominently composed of a combination of fibroblastic & histiocytic cells. Fibrous histiocytoma can usually be seen as either cutaneous types or involving deep tissues. The diagnosis of fibrous histiocytoma is only confirmed after surgical excision. It is imperative to differentiate this lesion from the other aggressive forms of fibrohistiocytic neoplasms. Atypical Fibrous Histiocytoma (AFH) comes in the spectrum of fibrous histiocytic lesion ranging from benign to malignant lesions. Atypical Fibrous Histiocytoma in oral cavity is distinctly uncommon. This uncommon occurrence of the lesion needs to be made known of, to prevent inappropriate treatment. Hence, here we present an uncommon case report of Atypical oral fibrous histiocytoma which presented clinically as epulis fissuratum/ Inflammatory fibrous hyperplasia
