Abstract:
Solitary Fibrous Tumor (SFT) is a rare benign neoplasm primarily associated with the pleura. However, it has also been identified in diverse locations, including the skin, deep soft tissues, genitourinary system, gastrointestinal tract, and the head and neck region, including the oral cavity. There is no gender predilection for SFT of the oral cavity and it can occur at any age. We herein present a case of SFT on the lower lip of a 19-year-old male patient and describe our diagnostic approach. The histopathological findings showed typical features of SFT with immunoexpression of CD34, CD99, BCL2, and STAT6, along with low expression of Ki67 in 10% of the tumor cells.
