Renal Cell Carcinoma with Unusual Visceral and Cutaneous Metastasis

Renal cell carcinoma is a common urogenital malignancy. It often metastasizes to the lungs, liver, bone, adrenal glands, and brain in the advanced stage. However, the involvement of the skin and subcutaneous region of the head and neck is rare. We report a case of a middle-aged man presented with extensive metastases to post radical nephrectomy. The nose and lower lip metastasis with submental lymph nodal mass is not previously reported. He also had metachronous prostatic adenocarcinoma. The case highlights the excellent capability of molecular imaging using fluorodeoxyglucose-positron-emission tomography/computed tomography to pick up all metastatic lesions and find metachronous prostate malignancy.
