Papillary serous carcinoma of the broad ligament: a rare case report.

Primary broad ligament carcinomas unassociated with either uterine or ovarian disease are extremely rare. This case report deals with such a rare occurrence of primary broad ligament carcinoma of the serous papillary type with foci of transitional differentiation in a 40 yr old woman with a clinical diagnosis of multiple fibroids of uterus. The highlight of this case is that besides being a rare tumor occurring in an unusual site such as the broad ligament the papillary serous carcinoma reported here also has a unique feature of transitional cell differentiation.
