The patient, however, died due to

The patient, however, died due to pulmonary metastasis 3-4 months after diagnosis. Figure 1 The primitive neuroectodermal tumor with strong immunoreactivity for CD99, vimentin, and CK5 markers. The second patient was a 24-year-old virgin with 10kg weight loss and dull aching in the lower abdomen. She had suffered from weakness in the lower extremity for the past three months. Physical examination revealed Inhibitors,research,lifescience,medical an irregular, non-tender mass

(30×35 cm in diameter), involving the left lower abdomen with extension to the xiphoid. Pelvic ultrasonography revealed a multi-loculated, echogenic mass in the pelvis and abdomen, and CT-scan identified a large retroperitoneal mass with liver metastasis (figure 2). The CA-125 concentration was elevated at Inhibitors,research,lifescience,medical 412, and the level of LDH was 5911, but the other tumor markers were normal. The initial appearance of the tumor suggested a diagnosis of sellckchem ovarian carcinoma. In exploratory laparotomy, an ovarian mass with friable attachment to pelvic peritoneal surfaces was encountered. Frozen section

identified the malignant tumor as probably a granulose cell tumor. Surgical staging of ovarian cancer with fertility-sparing surgery was performed. During laparotomy, a great deal of unusual lymphadenopathy was observed in the pelvic and paraaortic area. Further permanent pathology analysis of the surgical specimen and immunohistochemistry Inhibitors,research,lifescience,medical showed negative immunoreactivity for inhibin and revealed an http://www.selleckchem.com/products/Trichostatin-A.html undifferentiated malignant neoplasm, consisting of malignant small round cells Inhibitors,research,lifescience,medical with monomorphic nuclei and scant cytoplasm with features most consistent with the PNET. Immunohistochemical profile, positive immunoreactivity for CD99, CK, and vimentin were suggestive of the PNET. Ten days after surgery, because of the patient’s headache and paresthesia in the extremities, MRI was performed and detected a heterogeneous mass in T4 and T5. She underwent emergency laminectomy due to head and neck metastasis. The patient was subsequently treated with chemotherapy (BEP regimen), but she died due to brain metastasis before completing all the courses of chemotherapy.

CD99. The third patient was a 43-year-old woman (G3 P3) with a history of pelvic pain and distention in the hypogastric area. In pelvic examination, a large, solid, round mass (about 25×30 cm in diameter) with extension to the umbilical area was detected. Pelvic ultrasonography revealed a well-defined, mixed, echogenic mass (mean diameter=22×35 cm) in the right adnex with internal echo with adhesion to the surrounding organs and little ascetics. All tumor markers were normal (CA-125=25 and CEA=4). Exploratory laparotomy showed an irregular, solid mass (about 20×30 cm in diameter) in the right ovary that had infiltrated the other organs of the pelvis. Frozen section reported a malignant tumor, most probably adenocarcinoma of the ovary. Accordingly, surgical staging surgery was performed.
