Cytodiagnosis of a Cutaneous Clear Cell Malignancy: Metastatic Renal Cell Carcinoma on Chin

Recurrent renal cell carcinoma presenting as a cutaneous metastasis: A case report and review of the literature

Renal cell carcinoma (RCC) is a common urological malignancy. Despite early detection and surgical treatment, some lesions recur late at distant sites. The most common dissemination sites are lung, bone, and liver. Skin metastases are not common, and the incidence and clinical manifestations are poorly established in the literature. We report here the case of a male patient with an isolated scalp cutaneous metastase of RCC, 7 years after radical nephrectomy. An excisional biopsy was performed and confirmed metastatic RCC.

Cutaneous metastasis of renal cell carcinoma: Fine needle aspiration provides rapid diagnosis

The diagnosis of cutaneous metastasis of renal cell carcinoma is challenging in a young person in absence of a prior history of cancer. In such situation, fine needle aspiration alone as a minimally invasive procedure can provide rapid, accurate and cost effective diagnosis, even in case of unknown primary.
