Sumario:Introduction: Fibroadenomas are one of the most common benign breast lesions, however they have also been found on rare occasionselsewhere. These lesions usually arise frommammary-like glands (MLG) of the anogenital region which were first describedby van der Putte.Methods: This case is about a 51-year-old female who presents with symptomatic hemorrhoids and a 5 cm nodular lesion externalto the anal verge. These were removed and examined histo-pathologically.Results: Pathology revealed three hemorrhoidal specimens and the nodular lesion which was consistent with a fibroadenoma.Histologically, the nodular lesion demonstrated a benign process with ductal proliferation and estrogen receptors.Conclusions: Fibroadenomas in anatomic locations other than the breast are very uncommon. Other sites noted in prior casereports include gallbladder, prostate, arm, eyelid and anogenital region. Most of the anogenital lesions have been found on thevulva, with only six documented cases in the anal region, making this pathology exceedingly rare.
