Male breast cancer with radiological and histopathological findings

Objectives We aimed to remind and emphasize the importance of male breast cancer with radiological and histopathological results of the patients diagnosed in our institution. Methods Men who had proven breast cancer by histopathological analysis between February 2010-April 2018 were reviewed retrospectively. The mammographic, ultrasonographic, magnetic resonance and positron-emission-tomography imaging features and histopathological results of the masses were noted. Results Twenty-five men were included in this study. Mean age of the patients was 62.9 (min:42; max: 82) with a mean size of lesions was 26.4 mm (min:10 mm; max: 70 mm). All the lesions were presented as a palpable mass. According to imaging features of the five patients who had mammography, all the four patients were presented as a mass but one patient as asymmetrical density. According to imaging features of the 20 patients who had an ultrasound, 16 (80%) lesions were presented as hypoechoic solid masses with irregular margins, while four (20%) were presented as complex-cystic masses with irregular margins. All the patients were diagnosed as invasive ductal cancer with luminal subtype by histopathological analysis. Conclusion Even at young ages, the palpable lesion may be the only symptom of male breast cancer. Male breast cancer is generally presented as retroareolar mass and detected in advanced stages, probably due to low awareness and lack of screening programme. Invasive ductal cancer is the most common type of male breast cancer with the luminal subtype.
