Abstract

Benign fibrous histiocytoma (FH) is a benign tumor composed of fibroblasts and histiocytes in varying proportions. This tumor is usually found in adult extremities but rarely occurs in deep soft tissues of the oral cavity. As it is difficult to diagnose with physical and radiologic exams, deep benign FH can only be diagnosed by histopathology. We report a case of a 36-year-old female patient who came to our department with painless swelling in the right buccal mucosa. This case report reviews the clinical, radiological, and histological aspects of this tumor.
