Paratesticular papillary serous cystadenocarcinoma--a case report.

ABSTRACT

A case of paratesticular papillary serous cystadenocarcinoma in a six year old child is presented. The occurrence of these epithelial tumours of the ovarian type, in the paratesticular region is extremely rare and only six cases have been reported so far. They are thought to arise from Mullerian metaplasia of the peritoneal lining of the tunica vaginalis, appendix testis or mullerian remnants between the testis and spermatic cord.
