Multiple Primary Synchronous-Methacronous Cancer of Kidneys and Prostate Gland (Clinical Case)

Primary multiple tumors are an independent emergence and development two or more neoplasms in one patient. Thus can be the struck not only different bodies of various systems, but pair bodies (mammary glands, lungs, etc.) also, and one body with multicentric defeat. Primary multiple tumors can be synchronous and metachronous. The increase in frequency of multiple neoplasms is noted in recent years. A clinical observation of a 62-year-old patient with synchronous-metachronous primary-multiple cancer of both kidney and prostate gland is presented. A feature of this observation is multiple lesions of both kidneys, as well as the presence of two different morphological forms of renal cell carcinoma in one kidney (papillary and clear cell). The difficulty in identifying and differentiating kidney tumors with a cystic structure was due to the presence of multiple cysts of both kidneys of different types according to Bosniak.
