Although acrometastases are rare but clinically they are considered important. Their etiology is quite different from the metastases to other sites; bronchogenic carcinoma is by far the most frequent case. The prognosis is always similar to metastatic bronchial cancer with an average survival of three months. Treatment may involve distal digital amputation or antalgic radiotherapy. The main differential diagnosis is aggressive digital papillary adenocarcinomas (ADPA) that is a rare sweat gland neoplasm. A case of bronchogenic carcinoma with metastasis to the index finger is presented. The metastasis was located in the distal phalanx of the left index finger. Although acrometastasis is rare, it should be considered in the differential diagnosis of distal lesions, especially in elderly patients.
