ABSTRACT
Renal cell carcinomas are known to produce widespread and unpredictable metastasis due to their angioinvasive property. Cutaneous metastases from renal cell carcinomas are very rare, with a reported incidence of 1.3-3%. The sites of cutaneous metastasis from renal cell carcinomas, as per the available case reports, to the best of our knowledge, are shoulder, arm, nape of the neck, chest, face and scalp. We report a case of 63-year-old male, with renal clear cell carcinoma with lung metastasis who had cutaneous metastasis to the fingertip which was confirmed by histopathological examination. Apart from its rarity, this clinical case adds another site of renal cell carcinoma metastasis to the present literature. The skin metastasis represents a widely disseminated state of the disease with a very guarded prognosis and limited life span after its diagnosis.
ABSTRACT
Renal cell carcinoma is the third most common malignancy to metastasize to the head and neck region. Among them, parotid is a well-reported site, although limited to case reports. Tumours with predominance of clear cells found in the head and neck, namely oncocytoma, clear cell carcinoma, acinic cell carcinoma, mucoepidermoid carcinoma and epithelial-myoepithelial carcinoma should be distinguished from clear cell renal cell carcinoma. This case report is regarding a patient with renal cell carcinoma presenting as bulky parotid metastasis. This literature review is to reiterate the possibility of renal cell carcinoma with parotid metastasis, as to aid in good science and better practice.
