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 16th sustainment brigade patch 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 mars landing kale a mesonephric-like adenocarcinoma.Recognizing collision tumors consisting of slow-growing and aggressive tumors may prove beneficial in future diagnostic and treatment strategies.
