Hemangiopericytoma of Gingiva in a 4-Year-Old Child: A Rare Case Report.

A hemangiopericytoma is a type of soft tissue sarcoma that originates in the pericytes in the walls of capillaries which was characterized in 1942. It is commonly seen in the age group of 5th-6th decades of adults and only 5-10% of cases occur in children with extreme rare occurrence in head and neck region (16%). A rare case of hemangiopericytoma in a 4-year-old female patient is presented here and its clinical, histopathological and immunohistochemically features are discussed. Though surgical resection remains the mainstay, excisional biopsy was primarily performed to reach the final diagnosis. Even in the follow-up phase of 1 year, no recurrence or no metastatic changes were observed.
