“…It could be due to coincidental occurrence of two different cell lines growing in the same tissue. 4 Other possible hypothesis is origin of 2 different cell lines from a common precursor pleuripotent stem cell. 5 Other hypothesis suggested is of alteration of microenvioronment due to effect of carcinogenic agents of primary tumours or oncogenic growth factors of metastatic tumours.…”

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.

“…in a study conducted at seoul national university college of medicine, the authors reviewed seven pathologically proven cases of collision tumor of ovary associated with teratoma. Ovarian teratomas were co-existent with mucinous cystadenoma (4 cases), borderline mucinous tumor (1 case), muucinous cystadenocarcinoma (1case), and dysgerminoma (1case) [10] Although pathogenesis of collision tumours is not well understood some of the hypotheses put forward to explain are: The occurrence is coincidental, especially in tumors originating from neighboring tissues [12,13] or chance apposition of two unrelated tumors [14]. Simultaneous proliferation of two different cell lines [14].…”

“…Common origin from pluripotent precursor stem cell that differentiates into two components [14]. A carcinogenic agent may interact with different tissues, inducing different tumors [12,13]. Alteration in the microenvironment, such as angiogenesis and inflammation, by the primary tumor could facilitate the growth of metastases from a second primary tumor from another organ [15,16].…”

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.

“…Collision tumor has been described as two contiguous masses composed of two different morphological and immunohistochemical components coexisting in the same organ, in adjacent organs or as metastases from one organ to another [3]. In children, it could develop in a wide range of anatomic locations, including the brain, bone, and skin [4][5][6].…”

We presented a 5-month-old boy with differentiated neuroblastoma and ossifying renal tumor of infancy (ORTI) arising at the left adrenal gland and upper pole of the ipsilateral kidney, respectively. They were located in the adjacent organs with different morphology and immunohistochemistry characteristics. To our best knowledge, coexistence of differentiated neuroblastoma and ORTI in a patient has never been reported. In our report, two contiguous lesions might be represented collision tumor, originated from the same clusters of immature cells and triggered by different mechanism.
