    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.

    Contrast-enhanced spectral mammographic findings of phyllodes tumor of the breast
    Orguc, S; Mavili, S; Açar, ÇR; Aydede, H; Kandiloglu, AR
    Background: Phyllodes tumors of breast are rare fibroepithelial neoplasms. They have similar radiological findings with fibroadenomas. While fibroadenomas are benign lesions, phyllodes tumors may have malignant potential. Therefore, any imaging findings to differentiate fibroadenoma from phyllodes tumor are valuable. Case presentation: A 51-year-old female patient was admitted to our clinic with the complaint of a palpable mass. Tru-Cut biopsy resulted as phyllodes tumor, and excision was recommended. However, the patient neglected herself during the COVID-19 pandemic, and 20 months later, she presented with a huge and complex mass. On CESM imaging, cystic areas and clefts were identified. The case was diagnosed as borderline phyllodes tumor. Conclusions: Although MRI findings of phyllodes tumor are well known and reported many times, there is no information about CESM findings of this tumor in literature. Bubbly appearance on CESM is useful finding in the diagnosis of phyllodes tumor of breast.
