Acrometastasis accounts for 0.1% of all cases of metastatic cancer, with the most common primary tumor being lung cancer. Since acrometastasis is extremely rare and it generally has a nonspecific clinical presentation, it provides a diagnostic dilemma. We present a case of a 70-year-old female with a painful swollen right index finger which was found to be a metastatic lesion from adenocarcinoma of the lung. The patient expired within one month of diagnosis due to complications from her rapidly progressive metastatic cancer.
