A rare clinical presentation of carcinoma of the lung; acrometastasis of distal phalange: A case report

Acrometastasis, the metastasis of cancer to the distal extremities, is extremely rare, with the hand or foot being involved in only 0.007%–0.3% of metastatic cases. It is often a late sign of malignancy, typically seen in lung and breast cancers. We report a case of a 63-year-old male with swelling in the left ring finger, which was diagnosed as acrometastasis from an underlying primary lung cancer. Despite surgical amputation, palliative chemotherapy, and supportive care, the patient had a poor prognosis, with survival limited to only a few months. This case emphasizes the rarity of acrometastasis as the initial indication of malignancy and its associated poor prognosis.
