Cutaneous Metastasis from Renal Cell Carcinoma.

A 73-year-old man presented with a red papule on the posterior aspect of his neck (Figure 1). The growth had first been noted approximately 1 month before his visit. The patient complained of irritation from his collar but had no other symptoms. He had hypertension controlled by medication and denied recent weight loss, malaise, or swollen glands. Examination of the lesion revealed a firm, bright red papule 4 mm in diameter on a slightly indurated flesh-color base. (SKINmed. 2019;17:65-66).
