Recurrent malignant melanoma presenting as multiple bilateral breast masses: A case report.

Malignant melanoma is a tumor that originates from melanocytes. Melanoma commonly metastasizes to the lungs, brain, or any other solid organ. Herein, we describe the case of a 69-year-old woman with a previous history of cutaneous melanoma who presented with a newly developed palpable breast mass. Subsequent imaging findings and histopathologic examination results of biopsy specimens revealed bilateral breast masses consistent with malignant melanoma. Most breast malignancies originate from a primary breast cancer tissue. This case highlights the importance and implications of obtaining a complete medical history when evaluating the possible outcomes of malignant melanoma.
