診断に苦慮した卵巣腫瘍合併上顎洞悪性線維性組織球腫(MFH) A Case of Malignant Fibrous Histiocytoma of the Right Maxillary Sinus : Associated Ovary Tumor
Malignant fibrous histiocytoma (MFH) is one of the most common soft tissue sarcomas of the extremities. MFH arising from the maxillary sinus region are extremely rare. We experienced a case of MFH of this region in a 61-year-old female. She was admitted with the chief complaints of right cheek swelling and swelling of the gingiva around the right maxillary molar area. Biopsies of the nasal cavity and maxillary gingiva indicated malignant schwannoma or MFH. Furthermore, a pelvic tumor larger than 10cm was found. We performed excision of the pelvic tumor and total maxillectomy. Histological diagnosis was fibroma of the ovary and MFH of the maxillary sinus. Postoperative radiation therapy (total dose: 50Gy) was performed. No recurrence has been observed for more than 5 years after surgery.
