We report a case of torsion of ovarian carcinoma pedicle during chemotherapy with bevacizumab and FOLFIRI. A 47-year-old-female who had undergone laparoscopic-assisted sigmoidectomy for sigmoid cancer with multiple metastatic liver tumors, was treated with 3 courses of FOLFOX4 and 9 courses of FOLFIRI. Bevacizumab (BV) was started to administer with FOLFIRI since a CT scan had revealed that metastatic liver tumors had enlarged . Four days after final administration of BV (13th course), she presented lower abdominal pain. CT scan showed an enlarged right ovary sized 20 cm, but no findings suggesting bowel perforation; therefore we assumed her pain was due to enlarged ovarian tumor, which might be metastasis from sigmoid cancer. Increased oral morphine could not relieve her pain. Then, along with sufficient information about the risks of the operation caused by BV, we proposed an operation to remove her enlarged ovary. Day 16 after final administration of BV, we undertook a laparotomy by lower median incision, and found a twisted right adnex with large necrotic ovarian tumor. Pathologists diagnosed the ovarian tumor as primary ovarian cancer. No complication related to BV occurred, and she was moved to the ward for internal medicine 13 days after operation.

Objectives: Urologists make a decision on whether to indicate staging procedures for primary lesions of bladder cancer by findings of cystoscopy. However, cystoscopic findings for prediction of muscle-invasive bladder cancer have not been fully evaluated., Methods: Two hundred seventy consecutive events of 165 patients with bladder cancer were included in this study. Multivariate analysis by a logistic regression model was applied to analyze cystoscopic findings for prediction of muscle invasion of bladder cancer., Results: Logistic regression analysis revealed that the size, stalk and configuration of the cancer were independent and significant factors that predict muscle invasion of bladder cancer., Conclusions: Cystoscopic findings of bladder cancer may predict muscle invasion. When invasion is suggested by cystoscopy, imaging studies may be necessary before TUR of the cancer as well as deep resection of it.

Primary carcinoma of the duodenum is a rare lesion. In conjunction with the widespread use of panendoscopy, reported cases of carcinoma of the duodenum have recently increased. Although benign hyperplasia of Brunner's gland is well documented, duodenal carcinoma originating in Brunner's gland is extremely rare, and, consequently, there is little data on the morphological or histochemical characteristics. We report here a case of early duodenal carcinoma arising from Brunner's gland, whose origin was proven by mucin immunohistochemistry.
