Selected AbstractsSquamous cell carcinoma of the urachusINTERNATIONAL JOURNAL OF UROLOGY, Issue 10 2007Chisato Fujiyama Abstract: A 64-year-old man was admitted with complaints of abdominal pain and pollakisuria. A soft mass was palpable under his navel. Magnetic resonance imaging (MRI) revealed a 9 × 6 cm tumor, which was composed of a cystic lesion arising from the urachus and a solid mass component at the urinary bladder dome. Urine cytology specimens showed squamous cell carcinoma (SCC). Serum SCC level was increased and the tumor was removed surgically. Histological examination detected well-differentiated SCC, which had invaded the urinary bladder and the peritoneum. The patient has been followed up without recurrence for 6 months. [source] Mixed neuronal,glial tumor of the digestive tract: Distinctive entity from gastrointestinal stromal tumor?PATHOLOGY INTERNATIONAL, Issue 2 2002Marie-Laure Chambonniere A 53-year-old-woman presenting with pelvic discomfort was found to have a 9.5 cm tumor located in the wall of the ileon. Light microscopy showed that the tumor was made of fascicles of plump spindle cells and bizarre epithelioid cells. A cuff of lymphoid cells was also present at the tumor margin. The tumor cells strongly expressed tau protein, neuron-specific enolase, protein green product 9.5 and glial fibrillary acid protein (GFAP), but did not show positive immunostaining for S-100 protein, CD34 or CD117. The tumor showed unequivocal ultrastructural evidence of neural differentiation. Skeinoid fibers were scattered throughout the tumor. This is the first mixed neuronal,glial tumor of the digestive tract to be described in the literature. Such histological and immunohistochemical features could be misinterpreted as features of digestive schwannoma. We suggest that this tumor is distinct from gastrointestinal stromal tumors in lacking CD34 and CD117 expression. [source] Multiple extragenital adenomatoid tumors in the mesocolon and omentum,APMIS, Issue 11 2008CHI-JU YEH Adenomatoid tumors are benign mesothelial neoplasms most commonly found in the male and female genital tracts. Extragenital adenomatoid tumors are rare, most of them being solitary tumors. To our knowledge, only one case of multiple extragenital adenomatoid tumors, involving the liver and peritoneum, has been reported to date. Here we report another case of multiple extragenital adenomatoid tumors involving the mesocolon and omentum. A 47-year-old woman presented with a delayed menstrual period. Ultrasonography revealed a left adnexal mass, and surgical resection was attempted at a local hospital. The patient was transferred to our hospital without resection due to the intraoperative finding of multiple peritoneal tumors. At our hospital, an 8.0×7.5×6.0 cm tumor at the mesocolon of the sigmoid colon and three omental nodules measuring up to 2.5×2.0×1.7 cm were resected. Grossly, they were well circumscribed, gray-tan and elastic with small cystic spaces. Microscopically, they were composed of tubules and anastomosing channels lined by flattened or cuboidal cells with bland nuclei. Immunohistochemically, the tumor cells were positive for pan-cytokeratin AE1/AE3, vimentin, cytokeratin 5/6 and calretinin. The postoperative course was uneventful, and the patient was well 10 months after the operation. Despite their rarity, adenomatoid tumors should be included in the differential diagnosis of multiple intra-abdominal tumors.

Paulino MD Abstract Objective To determine the value of postoperative radiotherapy (RT) in the management of nonrhabdomyosarcoma soft tissue sarcoma (NRSTS) of childhood. Procedure From 1964 to 2000, 62 children with a median age of 14 years were seen at the University of Iowa and underwent a wide local excision for non-metastatic NRSTS. Tumors were high grade in 36 (58%) and >5 cm in 24 (39%). Margins of resection were negative (Group I) in 37 (60%) and positive (Group II) in 25 (40%). Postoperative RT was delivered to 20 patients (32%); eight of 37 (22%) Group I and 12 of 25 (48%) Group II children received postoperative RT. Chemotherapy was employed in 19 patients (31%). Median follow-up was 9.6 years. Results The 5- and 10-year overall survival rates for Group I were 69 and 63% and for Group II were 66 and 60%. The 5- and 10-year local control rate was 66%. On multivariate analysis, size of tumor (P,<,0.001) and postoperative RT (P,=,0.017) were prognostic factors for local control. All 13 Group I children with low grade, ,5 cm tumors were locally controlled without RT. For Group II patients, 2- and 5-year local control rates were 92 and 82% with postoperative RT and 51 and 43% for no RT (P,=,0.0426). Conclusions Local control was improved by the addition of postoperative RT in tumors with positive margins of resection. © 2004 Wiley-Liss, Inc. [source] | ||||||||||
