“…Collision tumour is coexistence of two dintinct tumours in the same organ without any histological intermixing [7]. Previous reports have detailed collision tumors in several organs other than the ovary, including the esophagus, stomach, liver, lung, thyroid and kidney [8,9].…”

Collision tumor is defined as the coexistence of two adjacent, but histologically distinct tumors without histological admixture in the same tissue or organ. Collision tumors involving ovaries are extremely rare. The coexistence of a mucinous cystadenoma with a dermoid cyst is infrequently reported. However, the most common histological combination of collision tumor in the ovary is the coexistence of teratoma with mucinous tumors. Recognizing the potential for the coexistence of these two neoplasms in the same ovary is essential to be able to make a correct diagnosis. we report here a rare case report of ovary comprising mucinous cyst adenoma and mature cystic teratoma. The case was diagnosed postoperatively. It is important to correctly diagnose the component of tumour for further management and favourable prognosis.

A collision tumour is defined by presence of two separate tumors in one organ on gross, microscopic and immune-histochemical studies without any admixture. These tumors are reported from oesophagus, stomach, liver, lung and thyroid glands. Such tumors are extremely rare in ovary. In case of ovaries most common histological collision reported between mucinous tumors and teratomas. We are reporting a rare combination of fibrothecoma with serous cystadenoma in right ovary of a premenopausal woman. Both gynaecologist and pathologist should be aware of such combination. It is important to differentiate such tumors from malignant ovarian tumors. Frozen section and scrape cytology are important tools which help in appropriate management of such cases intraoperatively.

“…Most common histologic combination of collision tumor in the ovary is coexistence of teratoma with mucinous tumors. [1,5] Here, to the best of our knowledge, we are describing the first case of collision tumor of right ovary comprising benign cystic teratoma and mucinous cystadenoma coexisting with contralateral benign cystic teratoma presenting in first trimester in primigravida.…”

“…[1] Either two different types of tumors may arise independently or metachronously at the same place or one or both malignancies may metastasize to the same location. They must be differentiated from "composite" tumors, which consist of a malignant neoplasm that has differentiated into two distinct subtypes.…”

Collision tumors involving ovaries are extremely rare. Here, we report this rare entity in a 23 years old primigravida presented with 12 weeks pregnancy and abdominal pain. Ultrasonography showed large right adnexal mass measuring 20 x 13 cm. having solid area with multiple cysts and bulky left ovary of 6 x 4.6 cm. Normal ovarian tissue was preserved after bilateral ovarian cystectomy. Grossly, right ovarian tissue revealed multiloculation and mucin filled cysts. Left ovarian cyst was filled with hairy pultaceous material. Histological diagnosis of collision tumor of right ovary comprising hemorrhagic mucinous cystadenoma and benign cystic teratoma along with dermoid cyst in left ovary was rendered. The pathogenesis of association of mature cystic teratoma with a mucinous cystadenoma has yet to be answered and the choice of management necessitates a weighing of risks based on characterization of the adnexal mass and gestational age.
