Abstract
Because lesions of the male breast have been exceeded in number by those of the female breast, marginal attention was given to these lesions in the past. Fortunately, this has changed over the years leading to an increased awareness about male breast cancer. Although male breast cancer constitutes only about 1% of all diagnosed breast cancer cases, an increased mortality is seen in this patient population. This is probably caused by late diagnosis as a consequence of low level of concern about breast cancer among male patients.
However, the vast majority of lesions of the male breast are benign, gynecomastia being the number one cause of unilateral or bilateral breast mass. Since it is important to avoid unnecessary surgical treatment without missing malignancy, accurate diagnostic tools are necessary in order to triage these patients. Fineβneedle aspiration biopsy has demonstrated excellent accuracy in the diagnosis and management of breast lesions in female patients. In addition, several authors have proven the value of this technique in the evaluation of lesions of the male breast. Fineβneedle aspiration biopsy permits accurate diagnosis in many lesions arising in the male breast. It also allows gathering cytological material that can be used for ancillary studies which enhances the diagnostic value of this technique. Diagn. Cytopathol. 2012. Β© 2011 Wiley Periodicals, Inc.
