FERREIRA, José et al. Acrometástase como manifestação primária de adenocarcinoma pulmonar. Rev. Port. Ortop. Traum. [online]. 2012, vol.20, n.4, pp.465-469. ISSN 1646-2122.

Bone metastases of the hand and foot (acrometastasis) are rare. The presentaction vary, being generally confused with inflamatory process such as rheumatoid arthritis, gout, tenosynovitis, fracture or infectius process (paronychia, osteomyelilis). The etiology of non-digital acrometastasis is common to the primary tumors with bone metastasis (prostate, lung, kidney, breast and gastrointestinal). However, the etiology of digital acrometastasis is almost exclusively broncogenic carcinoma. We report the case of a 43 years man. with an occult hung adenocarcinoma. He had persistent pain and swelling of the distal phalanx of the index finger of the dominant hand. Palliative amputation was performaned, with histological confirmation of hung adenocarcinoma. Rarely acrometastasis becomes symptomatic before the diagnosis of primary tumor. Physicians should be familiar with the strong association between digital acrometastasis and bronchogenic carcinoma. This way they will perform the appropriate diagnostic procedures in risk patients with digital complaints.
