Introduction: Choriocarcinoma is a gestational trophoblastic tumor that mainly affects women of childbearing age and rarely occurs in postmenopausal women especially following a long latent period from previous pregnancies. In this case report, we introduce three cases of postmenopausal choriocarcinoma with different clinical signs and symptoms. Case Report: The first patient was admitted with vaginal wall metastasis, and the second and third cases with postmenopausal vaginal bleeding. They were referred to the department of gynecology-oncology at Ghaem hospital in 2015. One case had stage I and two patients stage III of the disease. Treatment was initiated with EMA-CO regimen according to the histopathology of choriocarcinoma in these patients. Complete remission was achieved with chemotherapy for all three cases. Concusions: The possibility of choriocarcinoma should be considered as a differential diagnosis in postmenopausal vaginal bleeding and in postmenopausal women with metestatic lesions.

Introduction: Peritoneal tuberculosis (PTB) and ovarian cancer have overlapping nonspecific symptoms and signs. No pathognomonic clinical features or imaging findings can help to distinguish definite diagnosis of extra pulmonary TB. Peritoneal TB can be easily confused with peritoneal carcinomatosis or advanced ovarian carcinoma; therefore, it is difficult to distinguish these two entities. The current study described two cases of peritoneal tuberculosis mimicking advanced ovarian cancer. Case Presentation: In the first case, the initial manifestation was lower abdominal pain. The imaging indicated ovarian mass, ascites and hepatic surface nodularity, omental and peritoneal thickening. Also, titer of tumor marker CA-125 was more than 600 units. In laparoscopy, disseminated peritoneal seeding was observed. Frozen section of sampling these lesions reported tuberculosis. Biopsy of ovarian mass reported fibrothecoma. Concurrent with this patient, the second case referred to the same center,
