Abstract: Introduction: Collision tumour are the multiple contemporary tumours in a single organ, without histological admixture of each other. Because the components of the single or multiple tumours are separated from each other by stroma or by their basal lamina .It have been reported in various organs but are relatively rare in ovary. Possible collision tumour in the ovary are Cystadenocarcinoma and dermoid cyst, teratoma and mucinous cystadenoma, serous cyst adenocarcinoma and teratoma, carcinosarcoma and dermoid cyst, choriocarcinoma and cystadenoma. It can be benign or malignant. Mature Teratoma is one of the most common component of collision combination in ovary which consist of germ cell tumours. Case Report: 33-year-old female married from 6 years was came to gynaecology OPD with complaint of infertility and lower abdominal pain with normal menstrual history. Abdominal examination shows large abdominal mass arising from pelvis. Routine haematological and coagulation profile was normal Thyroid function test was within normal limits. Based on the USG findings a malignant neoplasm of the ovaries was suspected. Total abdominal hysterectomy with right salphingo oophorectomy was done and mass was resected and sent for HPR report. Histopathologic study revealed multiloculated ruptured mature teratoma with mucinous cystadenoma. Results: Gross - It was large encapsulated ruptured tumour mass occupying the ovary. Cut section shows two distinct features and both areas are complete demarcated. Major portion is solid, smooth and whitish in colour. Rest of the tumour showed complicated multiple cystic architecture. Microscopy - In microscopic findings, there were 2 main histologic component .The first component was mucinous cyst adenoma in which sections from cystic part showed cyst wall lined by mucin secreting epithelium and showing stratification. Second component was teratoma with mature elements in which Section from dermoid cyst shows cyst wall lined by flattened epithelium .Sub epithelium showed fibro collagenous tissue along with hair follicles and scanty mononuclear infiltrate also noted. Conclusions: It is important to correctly diagnose the component of tumour for further management and favourable prognosis. The rare reports of ovarian collision tumours may reflect insufficient recognition of the disease rather than a low incidence. Therefore, awareness of collision tumours is crucial to the ovarian tumour diagnostic process.
