Review of clinical cases of internal organ metastases into the skin of the head and neck

Abstract

Metastases of malignant tumors of the internal organs into the skin rarely occur, on average in 1–10 % of cases. They can be the first manifestation of malignant process in the absence of signs of the main disease or show progression of confirmed cancer. The article presents clinical cases of metastases of renal cell carcinoma and adenocarcinoma into the skin of the head and neck which currently is rare. Skin metastases are variable in their clinical manifestation. In the presented cases, resection of the lesions was required as symptomatic treatment.
