    Intestinal Ewing Sarcoma Misdiagnosed as an Adnexal Mass in a Young Woman
    Hasdemir, PS; Aliyeva, A; Mavili, S; Göksel, G
    Extraosseous Ewing's sarcoma is an extremely rare tumor. In the literature, intestinal Ewing's sarcoma was reported in 20 cases, and omental Ewing's sarcoma was reported in only two cases. In this case report, we report a 23-year-old female who presented with the complaint of diffuse abdominal pain. Abdominal ultrasound and whole-body computed tomography revealed a mass starting from the adnexal area and extending between the intestinal loops. Serum levels of tumor markers were high. The serum levels of carbohydrate antigen-125 (CA-125) and carcinoembryonic antigen-19.9 (CA-19.9) were high (427.5 U/mL and 67.9 U/mL, respectively). Laparotomic exploration was performed with the preliminary diagnosis of an adnexal mass, and a mass originating from the small intestine meso and completely covered by the omentum was excised. Histological evaluation reported intestinal and omental origin of Ewing's sarcoma. This case highlights the importance of rare extraosseous Ewing's sarcoma, which should be included in the differential diagnosis of a young female with intra-abdominal mass.

    Intestinal choriocarcinoma without primary source: A diagnostic enigma
    Sahin, ST; Hasdemir, PS; Atmis,Ö; Aliyeva, A
    Intestinal choriocarcinoma is a very rare phenomenon. This is the first reported case of intestinal choriocarcinoma following an ectopic pregnancy. We report a 24 year-old woman who presented with severe abdominal pain, distension, and vomiting. She had a history of an ectopic pregnancy nine months prior. Emergent laparotomy exploration revealed abscess formation and obstructions at two sites in the small intestine, with unremarkable gynecological organs. The obstructed sections of the intestinal were excised and subsequently diagnosed as intestinal choriocarcinoma in histopathological evaluation. Postoperative positron emission tomography (PET) revealed a non-contrast-enhancing lesion on the small intestinal wall with increased metabolic activity consistent with healing tissue at the anastomosis site. No other primary focus and/or metastatic lesions were detected. Multi-agent chemotherapy was planned for the patient. No residual and/or recurrent tumoral lesions were detected on the PET scan at the one-year follow-up.
