Mammography of the lesion shows a mainly well defined lesion with a slightly lobulated irregular anterior aspect. We decided to do an ultrasound guided puncture. The lesion proved to be mainly cystic with hemorrhagic fluid. After aspiration no mass was palpable anymore. However after aspiration of the hemorrhagic fluid a small irregular mass lesion remained.

The pathologist could not find any malignant cells in the hemorrhagic fluid. The core biopsy however showed the lesion to be an infiltrating ductal carcinoma. Had a blind puncture been performed without ultrasound the conclusion could have been that the lesion was benign.

Most breast cancers in male patients are solid lesions. However malignant cystic lesions exist and core biopsy is the method of choice to confirm malignancy.

Conclusion Mainly cystic ductal carcinoma of the breast in a male.
