Borderline papillary serous tumour of the fallopian tube

We report a case of borderline papillary serous tumor of the fallopian tube in a 31-year-old woman. The tumor was characterized by the formation of papillary projections with focally prominent epithelial stratification and atypia. The histologic features of the tumor were largely similar to a borderline serous tumor of the ovary. Two years after initial presentation, the patient underwent in vitro fertilization and carried the ensuing pregnancy to term. There is no evidence of disease nearly 6 years after presentation, which suggests that these extremely uncommon tumors can be managed conservatively.
