Multiple polypoid tumors in the jejunum or mid small intestine should suggest a diagnosis of Peutz-Jeghers syndrome or metastases, especially from malignant melanoma. Lipomas are smooth-surfaced, pliable, and often pedunculated lesions that have fat attenuation on CT (Fig. 46-37). The fat of a...
INTESTINAL tumorsUterine metastases from extragenital sites are rare. We present a case of a woman who had undergone surgery for small intestinal cancer and subsequently developed metastases in her left ovary and uterus. A nulliparous woman in her 50s underwent laparoscopic partial small ...
in larger cells with nuclear pleomorphism8. The immunohistochemical profile shows divergent differentiation, a striking feature of this tumor. DSRCT may present a problem in the differential diagnosis with other round cell tumors. Tumor cells are immunoreactive for epithelial, neural and myogenic markers...
Br-L19-SIP stability in mouse serum proved to be similar to that of the I-labeled analog (>80% of intact material at 48 h after injection). Fast and specific in vivo targeting was obtained in tumors and other organs expressing ED-B fibronectin (i.e., ovaries and uterus). However, ...
