The patient was an 86-year-old woman who had experienced nasal discharge and tearing of the left eye since August 1996. When she began noticing left nasal obstruction in December of the same year, she was referred to our clinic and examined in July 1997. A tumor that filled in the left nasal cavity was observed, and biopsy of the tumor led to a diagnosis of fibroma. Since the patient was elderly and had thrombocytopenic purpura as a complication, her condition was observed. In May 2000, the patient came to our clinic complaining of redness of the skin around the left eye, pain, a tumor in the medial angle of the left eye, and decreased visual acuity in the left eye. Because the computed tomography (CT) findings showed growth of the fibroma, left lateral rhinotomy was performed under general anesthesia, and the tumor, which extended from the nasal cavity to the anterior and posterior ethmoid sinuses, was excised. The tumor was attached to the posterior part of the nasal septum in the left nasal cavity, which was considered the primary site. The excised tumor measured 50mm×50mm×43mm in size and weighed 60g. The pathohistological diagnosis was fibromatosis. The visual acuity of the left eye improved postoperarively.
