A case of malignant melanoma in the thymus is reported. Diagnostic imaging demonstrated a left anterior mediastinal mass in a patient with giant pigmented nevus without malignant change. Histologic and cytologic specimens obtained from the tumor revealed that the tumor was malignant melanoma. Surgery revealed malignant melanoma in the left lobe of the thymus. Many cell nests of pigmented nevi were observed throughout the thymus. The malignant melanoma was thought to have originated from the nevocellular nevus in the thymus. This is the first report of malignant melanoma in the thymus.
