Abstract:
The phenomenon of a tumor-to-tumor metastasis is studied immunohistochemically. About 120 similar cases were published since 1902. Well vascularized and slowly growing renal tumors are typical recipients for such metastases. A case of a lung cancer metastasis verified immunohistochemically into renal adenoma is reported in a male aged 65 years. Immunophenotypical features of the primary and metastatic foci as well as renal cell adenoma are described. Diversification of lung squamous cell carcinoma and its metastasis in renal adenoma is demonstrated.
