Abstract
An incidental peritoneal nodule was noted intraoperatively when a man in his 30s was undergoing a reversal of a colostomy procedure. The peritoneal nodule macroscopically comprised a fibro-fatty piece of tissue and histologically demonstrated mature spermatozoa with surrounding histiocytic reaction. A diagnosis of sperm granuloma was made. Sperm granuloma typically occurs in the epididymis following damage to vas deferens. The peritoneal site is very rare and thus can be mistaken for a neoplastic process.
期刊介绍:
This monthly review journal aims to provide the practising diagnostic pathologist and trainee pathologist with up-to-date reviews on histopathology and cytology and related technical advances. Each issue contains invited articles on a variety of topics from experts in the field and includes a mini-symposium exploring one subject in greater depth. Articles consist of system-based, disease-based reviews and advances in technology. They update the readers on day-to-day diagnostic work and keep them informed of important new developments. An additional feature is the short section devoted to hypotheses; these have been refereed. There is also a correspondence section.
