Abstract
A case of leiomyosarcoma arising from the maxillary sinus is reported. The patient was a 74-years-old female who complained of swelling and pain in her left cheek since October 1994. A CT scan revealed a tumor shadow occupying the entire maxillary sinus. The tumor further extended to the surrounding tissue including the orbital floor. The patient was initially treated by chemotherapy, and later underwent a total maxillectomy on Feb. 3, 1995. The postoperative course was uneventful until a gastric cancer was found. Thereafter, her general condition progressively deteriorated and she passed away on March 29 1995.
