METASTATIC MALIGNANT MELANOMA OF THE BREAST: A CASE REPORT

Abstract

Metastasis of a malignant melanoma or any other type of tumour to the breast is rarely seen. A 70-year-old female patient came to the breast clinic due to a mass in her right breast. The case did not have any known history of malignincy. After the initial incisional biopsy, a right modified radical mastectomy and axillary lymph node dissection were performed. On the cut surface, a yellow to pink, solid and well-circumscribed tumoural lesion with a maximum diameter of 8 cm was observed. Given its histopathological and immunohistochemical attributes, the case was diagnosed as metastatic malign melanoma involving breast and ipsilateral axillary lymph nodes. This case was determined to be worthy of presentation due to the fact that the histological diagnosis of metastatic tumours can be more difficult than of primary breast cancers and that metastasis of malignant melanoma to breast is rarely seen.
