A Case of Fibrous Histiocytoma in Infratemporal Fossa and Parapharyngeal Space / 대한이비인후과학회지

ABSTRACT

Fibrous histiocytomas (FHs) are skin or deep tissue tumor that include a heterogenous group of tumors. The common origin of these tumors are a histiocyte and these tumors are composed of fibroblasts and histiocytes. FHs commonly occurs in the sun-exposed skin and subcutaneous tissue, but its incidence in the head and neck is rare. We experienced a case of FH in the infratemporal fossa and parapharyngeal space in a 29-year-old woman. The patient showed hyperesthesia in the right chin and some facial swelling. We could successfully remove the mass without sacrifice of important structures by infratemporal fossa approach with osteotomy of mandible.
