Hiperplasia ductal atípica de mama: correlación de la biopsia percutánea y los resultados de la biopsia quirúrgica

Objetive

The purpose was to evaluate the prevalence of carcinoma found at surgical biopsy of llesions identified as atypical ductal hyperplasia by percutaneous breast biopsy.

Methods

We performed a retrospective study of all asymptomatic patients with a result of atypical ductal hyperplasia on percutaneous breast biopsy and who underwent surgical excision from January 2002 to December 2010.

Results

Sixty-eight patients were found to have atypical ductal hyperplasia at percutaneous breast biopsy and were evaluated with surgical biopsy. Seventeen patients (25%) had carcinoma at surgical excision, 10 had ductal carcinoma in situ, and 7 patients had invasive carcinoma. The mammographic characteristics associated with malignancy were analyzed.

Conclusions

A finding of atypical ductal hyperplasia at percutaneous breast biopsy frequently corresponds to cancer and is therefore an indication for surgical excision.
