Abstract

Metastatic carcinoma on the hand occurs in 0.1% of all metastasis and the diagnosis is difficult since it frequently mimics other conditions such as infection, osteomyelitis, gout, and pseudoclubbing. A 70-year-old woman with lung carcinoma was consulted for the evaluation of a painful swelling patch on the tip of her right 2nd finger. She was initially treated with antibiotics due to the misdiagnosis of the condition as an infection. Her pain persisted for a month. The skin biopsy revealed a metastatic adenocarcinoma with papillary growth pattern. We report a rare and an interesting metastatic carcinoma manifesting as clubbed finger.
