报告一例国内未见报道的军见卵巢原发性岛状类癌。病人60岁,有左下腹痛及左下腹包块,没有任何类癌综合征或转移表现。切除左侧卵巢。肉眼标本为一实性棕至灰黄色瘤块,从皮样囊肿壁突入囊腔内。组织学检查瘤组织主要呈岛状类癌结构,与由中肠发生的类癌相似,肿瘤中伴有畸胎瘤成分。组织化学检查瘤细胞有少量嗜银阳性颗粒,但亲银染色阴性。超微结构检查瘤细胞胞质中有圆至椭圆形、大小较一致、电子密度高的分泌颗粒,形态和通常由前肠或后肠发生的类癌颗粒相似。复习文献约有124例原发性卵巢岛状和小梁状类癌报告,但有超微结构资料的仅11例。本文通过电镜对本例进一步确诊,并结合文献讨论了本例的特点。
Report a case of domestic unreported military see ovarian primary island carcinoid. The patient was 60 years old and had left lower abdominal pain and left lower quadrant mass without any carcinoid syndrome or metastatic manifestations. Left ovary removal. Macroscopic specimens of a solid brown to yellowish tumor mass, from the dermoid cyst wall into the cyst. Histological examination of tumor tissue was mainly island carcinoid structure, similar to carcinoid carcinoid by the midgut, tumor associated with teratoma components. Histochemical examination of tumor cells with a small amount of silver-positive particles, but negative silver staining. Ultrastructural examination of tumor cells in the cytoplasm round to oval, more consistent size, high electron density of secretory granules, morphological and carcinoid particles usually occur in the foregut or hindgut similar. Review of the literature about 124 cases of primary ovarian and trabecular carcinoid reports, but only 11 cases of ultrastructural data. This article further confirmed by electron microscopy in this case, combined with the literature discussed the characteristics of this case.
