摘要

术中发现一个偶然的腹膜结节，当时一名30多岁的男子正在接受结肠造口手术的逆转。腹膜结节宏观上由纤维脂肪组织组成，组织学上显示成熟精子，周围有组织细胞反应。诊断为精子肉芽肿。精子肉芽肿通常发生在输精管损伤后的附睾。腹膜部位是非常罕见的，因此可以被误认为是肿瘤过程。

A case of sperm cell granuloma presenting as a peritoneal nodule

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.
