Objective:

To assess the incidence of benign breast disease (BBD) in pathological specimens of patients undergoing reductive mastoplasty (RM). We studied the pathology reports of patients undergoing RM in a period of 10 years. The association between certain variants and the presence of BBD was analyzed. Of the total 314 patients, 136 (43.3%) presented BBD. The most common lesion was fibrocystic mastopathy (47.7% n = 65), representing 60.3% (n = 41 p = 0.004) of lesions in patients older than 40 years. The second most common lesion was ductal hyperplasia without atypia (46.3% n = 63), predominating in those under 40 years. Fibroadenomas were the most common lesions in those under 40 years (p = 0.002). 82.35% (n = 14 p = 0.004) of microcalcifications were in women older than 40 years.

Conclusions:

We found a relationship between age and type of injury. The incidence of BBD after RM in this study was 43.3%, percentage below 76.2% reported in the literature. This study helps us increase awareness in the medical community about the possible presence of lesions in the pathological specimen after elective breast surgery in healthy patients.
