Anticancer agents can induce sarcoidosis. Interferon-alpha, which is used for the treatment of malignant melanoma and renal cell cancer, is one causative agent of sarcoidosis. However, there are few reports of interferon-alpha-induced sarcoidosis in patients with malignant melanoma. Clinically, it is important to consider the possibility of sarcoidosis in such patients because it could be easily regarded as a metastatic lesion due to underlying malignancy and given unnecessary treatment. Here, we report on the first case of interferon-alpha-induced sarcoidosis in an Asian melanoma patient.
