Adenomatoid tumors are benign tumors of mesothelial origin seen in female genitourinary tract, most commonly involving the uterus and rarely fallopian tubes. We herein report a case of 46-year-old female who presented with abnormal vaginal bleeding with complex cyst in left adnexa and multiple leiomyomata upon pelvic imaging. Hysterectomy and bilateral salpingectomy were done. A circumscribed red-tan nodule, measuring 3.0 cm in maximum dimensions was identified on the left fallopian tube with a solid, homogenous yellow-tan cut surface. The histopathological examination revealed features of adenomatoid tumor supported by immunohistochemical stains positive for calretinin and cytokeratin and negative for CD34. This is a benign entity but need to be differentiated from malignant lesions owing to variable histopathological patterns and cytological features. These have good prognosis upon surgical removal with no evidence of recurrence. This case is being presented due to the rarity of adenomatoid tumors in this location along with the discussion of other potential differential diagnosis in this location.
