Adenomatose erosiva do mamilo

Abstract

Erosive adenomatosis of the nipple is a complex benign mammary proliferation that can be misdiagnosed as a malignant mammary neoplasm. The most common clinical presentation includes discharge, erythema, erosion and crusting. The process is usually asymptomatic. It resembles benign conditions such as contact dermatitis, psoriasis and infections, but its main differential diagnosis is Paget's disease. Treatment is usually surgical and the prognosis is excellent.

A case of giant nipple adenoma

“…In Japan, Sakumoto et al reported 34 cases in 1996 [ 2 ], Sugamata et al reported 31 cases in 2002 [ 3 ], and Uchida et al reported 60 cases in 2010 [ 4 ]. The most common reason for detection was a mass or induration (66%), followed by erosions or ulcers (48%) and nipple discharge (35%) [ 5 – 7 ]. In reports from Western countries, nipple discharge is common, but in Japan, erosions tend to occur more frequently, sometimes making differential diagnosis from Paget’s disease difficult [ 2 , 17 ].…”

“…These tumors most commonly arise in patients in their 40 s and 50 s, but there are reports of nipple adenomas occurring in children in their 10 s and in elderly patients in their 70 s [ [4]. The most common reason for detection was a mass or induration (66%), followed by erosions or ulcers (48%) and nipple discharge (35%) [5][6][7]. In reports from Western countries, nipple discharge is common, but in Japan, erosions tend to occur more frequently, sometimes making differential diagnosis from Paget's disease difficult [2,17].…”
