Diagnostic and treatment implications are discussed herewith.Adenocarcinoma admixed with neuroendocrine carcinoma of the uterine cervix is a rare malignancy with a poor prognosis. In the literature, there are few reported cases. Herein, we report a case of a 56-year-old Turkish woman with cervical adenocarcinoma admixed with small cell neuroendocrine carcinoma. Histological examination of endocervical curettage specimens revealed a tumor composed of almost equal areas of small cell neuroendocrine carcinoma and adenocarcinoma. Neuroendocrine differentiation was confirmed by immunohistochemistry for chromogranin-A, synaptophysin, and CD 56. After the adenocarcinoma and small cell neuroendocrine carcinoma association was detected in the curettage material, both cervicovaginal smear and then total abdominal hysterectomy and bilateral salpingo-oophorectomy resection material of the patient were submitted to our pathology department. Histological features of both curettage and resection material were determined by immunohistochemical studies.Collision tumor consists of two tumors occurring in the same organ without intermixture of the two cell types. The most common type of collision tumor in ovary is between teratoma and surface epithelial tumor. A 38-year-old woman presented with complained of lower abdominal pain and tightness, and a solid partially cystic left ovarian mass with minimal ascites was detected. Left salpingo-oophorectomy was performed. The ovarian mass measured 15 × 12 × 7 cm with a pedunculated mass on its surface which measured 6 × 2.5 × 2.5 cm. Histologically, it was a collision tumor of fibroma and mature cystic teratoma. Fibroma becomes more edematous as their size increases, which is frequently accompanied by the escape of increasing quan
