Radiological, histopathological, and immunohistochemical characterization of solitary fibrous tumor of the lacrimal sac: A rare case report

Solitary fibrous tumor (SFT) is a benign spindle cell neoplasm of mesenchymal fibroblast cells. It can appear in various locations, but SFT of the lacrimal sac is rare. Due to their variable clinical, histological, and radiological presentation, it can be easily misdiagnosed. We report a rare case of SFT of the lacrimal sac with its radiological, histological, and immunochemical characterization.
