Cutaneous metastasis of renal cell carcinoma masquerading as scrotal growth

Abstract

Cutaneous metastases are an uncommon manifestation of visceral malignancy. We report a case of a 56-year-old male who presented with an ulcerated scrotal mass and inguinal swelling on the left side. Fine needle aspiration from both the sites revealed deposits of renal cell carcinoma though the patient had no urologic symptoms. Subsequent work-up revealed a renal mass. This case emphasizes the importance of keeping renal cell carcinoma as differential in cases who present with cutaneous metastases.

Aggregates of tumor cells with low N/C ratio, central, round, bland nuclei, abundant, pale, fine granular, vacuolated cytoplasm, and ill-defined cell boundaries. The background was pale, foamy, and vacuolated admixed with RBCs (Giemsa stain, ×400). Inset shows metastatic deposit of renal cell carcinoma beneath the scrotal skin and muscular tissue (H&E, ×100)
