Introduction:
Metastatic melanoma to the breast is rare and may be misdiagnosed as primary breast carcinoma. Histological, immunohistochemical, and clinical correlations, such as a history of previous melanoma, are essential for diagnosis.
Patient Presentation:
A female patient presented with melanoma in the left gluteal region. Five years later, a palpable nodule was detected in the right breast on routine mammography. Microscopic and immunohistochemical examination confirmed the diagnosis of metastatic melanoma. The patient passed away 3 years later.
Conclusion:
The findings in this case indicate that metastatic melanoma can present in atypical ways and that specialists should pay attention to metastases in unusual locations in cases of melanoma.
