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 forma
tion of papillary projections with focally prominent epithelial strati
fication and atypia. The histologic features of the tumor were largely
similar to a borderline serous tumor of the ovary. Two years after in
itial presentation, the patient underwent in vitro fertilization and c
arried 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.
