A case of ovarian malignant mixed mullerian tumor (MMMT) with melanocytic differentiation is described. A 74-year-old woman presented with left lower quadrant pain. Pathologic examination of the left ovary revealed a MMMT, composed predominantly of serous carcinoma (90%) with a minor sarcoma component containing focal chondroid differentiation. There was also a single focus of malignant melanoma. Immunohistochemical studies showed that the latter was positive for S-100, HMB-45, and pan-melanoma cocktail, and was negative for synaptophysin and neuron-specific enolase. To the best of our knowledge, this is the first case of MMMT with melanocytic differentiation described in the ovary.
本文描述了一例卵巢恶性混合性苗勒管肿瘤(MMMT)伴黑色素细胞分化。一位 74 岁女性因左下腹疼痛就诊。左侧卵巢的病理检查显示 MMMT,主要由浆液性癌(90%)组成,伴有局灶性软骨分化的小肉瘤成分。还有一个恶性黑色素瘤的单一病灶。免疫组织化学研究表明,后者对 S-100、HMB-45 和泛黑色素瘤鸡尾酒呈阳性,对突触素和神经元特异性烯醇化酶呈阴性。据我们所知,这是首例卵巢恶性混合性苗勒管肿瘤伴黑色素细胞分化的病例。
