Abstract
Tumor metastasis in the skin can be seen either as a recurrence of a visceral malignancy of unknown primary origin or as a previously detected and treated malignancy. Breast cancer and Skin Metastasis of breast cancer is very rare among men. Male breast cancer accounts for 0.6% of all breast cancers and represents less than 1% of all male malignancies. Since breast cancer is not a common disease in men, its diagnosis can be easily missed, and most of the time it is not taken into consideration in the definitive and differential diagnosis. Breast cancer can be confused with non-healing chronic skin lesions on the breast skin. In this study, a male patient who had previously admitted to different physicians due to lesions on his left shoulder and chest skin was evaluated by taking a skin biopsy at his last admission. The diagnosis was metastatic carcinoma and it was reported that the primary focus might be the breast. Further tests and examination of the patient revealed a mass in the upper outer quadrant of the left breast and metastases in the left half of the neck, bilateral axillae, and lungs. The aim of this study was to emphasize the possibility of breast carcinoma in male patients, especially in chronic lesions of the breast-chest skin and to evaluate male breast cancers.
