[Benign breast diseases: clinical, radiological and pathological correlation].
BACKGROUND
Benign lesions of the breast are common; however, benign pathological states have always been neglected in comparison to cancer even though they account for as much as 90 percent of the clinical presentations related to breast. A useful classification system for benign breast disease has been described by Love and colleagues and is based on symptoms and physical findings, six general categories have been identified, which include physiological swelling and tenderness, nodularity, mastalgia, dominant lumps, nipple discharge, and inflammation. Another classification system developed by Page and coworkers separates the various types of benign breast lesions into three clinically relevant groups: non-proliferative lesions, proliferative lesions without atypia, and proliferative the histopathological evaluation of the biopsy specimen in order to determine the subsequent risk of developing carcinoma if the lesions represents atypia of lobules or ductal epithelium.


OBJECTIVE
The study was made to evaluate the clinical, radiological and pathological correlation of the benign breast lesions.


METHODS
We studied women aged 40 years or less that went to the Foundation Rodolfo Padilla Padilla by mastalgia or the presence of a mass. We determined the Kappa coefficient in order to identify the agreement between the three observers according to different pathologies: fibroadenoma, abscess, cyst, mastitis, fibrosis, and cancer.


RESULTS
We made 698 breast Ultrasounds in women younger 40 years, we found 52% ultrasound normal and 48% were reported with benign breast pathology: fibroadenomas 38%, cyst 27%, dilated ducts 24%, benign nodule 4%, mastitis 3%, ectasia 2%, and abscess 2%. The correlation was made to 58 patients, finding the following coefficients kappa. Fibroadenoma: when evaluating the clinical examination versus ultrasound: K = 50%. Cysts: when evaluating clinical examination versus ultrasound: K = 17%, when evaluating ultrasound versus pathology: K = 3%. Fibrosis: when evaluating clinical examination versus ultrasound: K = 56%, when evaluating ultrasound versus pathology: K = 50%, when evaluating ultrasound versus pathology: K = 50%.


CONCLUSIONS
The benign breast pathology must be studied carefully because the clinical and ultrasonic evaluation is not conclusive, and the histopathological evaluation of the biopsy specimens sometimes is necessary to discard malignancy.
