Metastasis of lung cancer to bone of the finger: a case report

Abstract

Introduction: Metastases of malignant neoplasms to the hand and wrist are rare. The lung, breast and kidneys are more common sites of primary lesions that metastasize in the hand. Phalanges are more commonly involved than the metacarpal and wrist.

Case report: We report the case of a metastatic tumour involving the distal phalanx of the little finger originating from lung cancer in a patient with a history of advanced neoplastic disease (stage III B). Lung cancer was diagnosed approximately 10 months prior to the occurrence of metastasis. The tumour in 

the finger grew slowly, causing enlargement of the distal phalanx, causing no pain and not interfering with the hand function. The diagnosis was made based on X-ray performed due to occasional trauma of the involved finger. Treatment of the metastatic tumour consisted in amputation of the finger. After healing of the stump the patient was referred to further palliative, oncologic care.
