Abstract：
Collision tumors of the ovaries are rare, with only a few reports in the literature. Adult granulosa cell tumors are a relatively common primary tumor component of previously reported collision tumors. The combination of serous and mucinous tumors with adult granulosa cell tumors has been reported in several cases. On the other hand, mesonephric-like adenocarcinomas are rare neoplasms that commonly arise in the uterine corpus and ovaries. In this report, we present the case of a collision tumor composed of an adult granulosa cell tumor and mesonephric-like adenocarcinoma of the ovary in a 63-year-old woman. The initial magnetic resonance imaging findings showed a cystic mass with an internal hemorrhage, which suggested an adult granulosa cell tumor, and a solid mass with different enhancements. Microscopically, the tumor had two distinct components: An adult granulosa cell tumor and a mesonephric-like adenocarcinoma. Recognizing collision tumors consisting of slow-growing and aggressive tumors may prove beneficial in future diagnostic and treatment strategies.
摘要：
卵巢的碰撞肿瘤很少见，文献中只有少数报道。成人颗粒细胞瘤是先前报道的碰撞肿瘤中相对常见的原发性肿瘤成分。在一些病例中已经报道了浆液性和粘液性肿瘤与成人颗粒细胞肿瘤的组合。另一方面,中肾样腺癌是罕见的肿瘤，常见于子宫体和卵巢。在这份报告中,我们介绍了一个由成人颗粒细胞瘤和卵巢中肾样腺癌组成的碰撞肿瘤的病例，该病例为63岁女性。最初的磁共振成像发现显示囊性肿块伴有内部出血，这表明成人颗粒细胞瘤，和具有不同增强功能的固体质量。微观上,肿瘤有两个不同的组成部分：成人颗粒细胞瘤和中肾样腺癌。认识到由缓慢生长和侵袭性肿瘤组成的碰撞肿瘤可能在未来的诊断和治疗策略中被证明是有益的。
