術後副鼻腔に初発した malignant histiocytoma の1剖検例

抄録

The patient, a 41-old female, had a maxillary-ethmoid sinectomy and intranasal ethmoidectomy about three years earlier in our hospital. She returned complaining of right cheeck pain and swelling. Right maxillary sinectomy was performed to remove a postoperative maxillary cyst.
The histopathological diagnosis was malignant histiocytoma in the ethmoid sinus. Radiation therapy and chemotherapy were given, but the patient died after three months.
Autopsy showedd metastases in the larynx, trachea, main bronchus, breast, heart, and uterus, but none in the reticulo-endothelial system, i. e. lymph nodes, bone marrow, liver or spleen.
Because the metastase of this tumor were different from the usual pattern, we think this is a very rare case.
