Carcinoma of the breast is the third most common primary tumor leading to metastases in the hand. It is preceded by carcinoma of the lung and kidney. A review of literature is presented, following the case report of an isolated skeletal metastasis in the middle phalanx of the left ring finger in a 67-year-old patient seven years after mastectomy of the right breast. At first, the findings were misinterpreted as enchondroma.
