Intranodal Palisaded Myofibroblastoma: A Diagnostic Differential for Inguinal Lymphadenopathy.

BACKGROUND Benign tumors of the lymph nodes are rare and are not usually considered in the differential diagnosis in cases of lymphadenopathy because reactive hyperplasia, lymphoma, and metastatic carcinoma are the most likely causes of enlarged nodes. Intranodal palisaded myofibroblastoma (IPM) is a very rare benign mesenchymal tumor of the lymph nodes most often affecting but not limited to the inguinal region, with up to 92 cases reported in the English literature. The cell of origin is the intranodal differentiated smooth muscle cell or myofibroblast.

Fournier gangrene in pregnancy.

Background: Fournier gangrene is a rare and rapidly progressive necrosis of the perineal and genitourinary region. Although predominantly affecting men, we describe an unusual presentation in pregnancy.

Case: A 30-year old primigravid woman in the third trimester of pregnancy presented with a history of low back pain.

The rate of abdominoperineal resections for rectal cancer in the state of Victoria, Australia: a population-based study.

Purpose: The aim of this study was to document a population-based rate of abdominoperineal resections for adenocarcinoma of the rectum in the state of Victoria, Australia. It also determined whether surgeon caseload or specialist colorectal training affects this rate.

Methods: All resections for adenocarcinoma of the rectum (International Classification of Diseases for Oncology, 3rd edition C20) that were performed in Victoria in the year 2005 were included.

Pneumothorax, pneumomediastinum, pneumoperitoneum, pneumoretroperitoneum and subcutaneous emphysema following diagnostic colonoscopy.

Colonic perforation is an unusual complication of colonoscopy. We present a case of pneumothorax, pneumomediastinum, pneumoperitoneum and extensive subcutaneous emphysema resulting from a diagnostic colonoscopy. To our knowledge, only two such cases have been described previously.

Definitive treatment of extended Hirschsprung's disease or total colonic form.

Background: Between December 1990 and March 1999, five laparoscopic Duhamel pull-through procedures for extended or total aganglionosis were performed in our department, one of which had a rectosigmoid form with a short bowel and a colonic resection due to a volvulus.

Methods: The aim of this study was to show that even when the extended form of Hirschprung's disease or anatomic difficulties such as a short bowel and anterior colonic resection are encountered, the laparoscopic approach is possible and total colectomy is feasible. The procedure has been described previously.
