Abstract

Solitary Fibrous Tumor (SFT) is a rare soft tissue tumor which has fibroblastic origin. SFT constitutes a heterogeneous group of rare spindle-cell neoplasms that include benign and malignant entities. It was originally described in the pleura. They may arise in non serosal areas like orbit, thyroid, nasal cavity and soft tissues. Herein, we present a case of 35 year old male who came with a painless swelling on the tip of the tongue. Histopathological examination of the excised tissue showed hypercellular and hypocellular areas with spindle shaped cells arranged in whorls and fascicles with interspersed collagen. Hemangiopericytomatous growth pattern was evident. Immunohistochemistry revealed positivity for Vimentin, CD34 and BCL-2, negativity for S-100, cytokeratin and desmin. IHC for Ki 67 revealed a low proliferative index. A diagnosis of solitary fibrous tumor was made. The case is being presented due to its rarity.
