title: Endoscopic-modified medial maxillectomy and its limitation for a solitary fibrous tumor of the lacrimal sac and nasolacrimal duct.
abstract: Solitary fibrous tumor (SFT) is an uncommon neoplasm that usually arises from the pleura. Recently, SFTs have been reported in the head and neck region located in subsites such as the orbit. SFTs of the lacrimal sac are extremely rare, with only six cases reported in the English literature. We describe a SFT arising from the right lacrimal sac and extending along the nasolacrimal duct into the nasal cavity. Although, the tumor could not be removed by endoscopic-modified medial maxillectomy (EMMM) alone, combined approach with EMMM and a small external incision achieved the complete removal of the tumor. The patient has remained disease-free 24 months after surgery.
