A Rare Presentation of Palpable Bilateral Male Breast Cancer: A Case Report.

INTRODUCTION

We present a case on bilateral invasive ductal carcinoma in a male patient who presented with two palpable masses with one side initially attributed to gynecomastia.

CASE PRESENTATION: The patient underwent left breast lumpectomy and sentinel lymph node biopsy and right breast excisional biopsy. Postoperatively, pathology confirmed bilateral invasive carcinoma with one out of eight positive lymph nodes in the left breast. This patient did not undergo further procedures and was established with medical and radiation oncologists. After discussion with the patient and multidisciplinary team, it was decided that chemotherapy and radiation would not benefit this patient. The patient is following up regularly in 3 months postoperatively followed by 6-month intervals and is taking tamoxifen to aid in prevention of recurrence.

CONCLUSION

The presentation of this case contributes to current breast cancer treatment and diagnosis, particularly in subset male population with an atypical presentation and unexpected diagnosis involving both breasts.
