Fallopian Tube Neoplasia and Mimics.

This review discusses select fallopian tube entities and their associated mimics. It first focuses on adenomatoid tumors, the most common benign tumor of the fallopian tube. High-grade serous carcinoma and its precursor, serous tubal intraepithelial carcinoma, are then addressed. Finally, attention is turned to endometrioid proliferations of the fallopian tube. A diagnostic approach is provided for these lesions, with an emphasis on differential diagnoses and situations in which a benign lesion may appear malignant, and vice-versa.
