title: A case of trichilemmal carcinoma with distant metastases in a kidney transplantation patient.
abstract: Transplant recipients receiving immunosuppressants are at a high risk of cancer, especially skin cancer. Trichilemmal carcinoma is comparatively rare compared with other skin cancers. We report here a first case of trichilemmal carcinoma arising in a kidney transplant recipient. A 63-year-old man who had undergone a living donor renal transplantation at the age of 50 years presented with a 15 × 10 mm lesion on his forehead. The pathological diagnosis after resection was trichilemmal carcinoma. Distant metastases involving the lymph nodes, lung, and liver occurred, and the patient died. Given that trichilemmal carcinoma generally has an indolent clinical course and a low metastatic potential, the present case of trichilemmal carcinoma with an aggressive course resulting in distant metastases is rare.
