TC-RCC was recognized as a distinct subtype of kidney cancer by the World Health Organization in 2016, while PV is a rare myeloproliferative neoplasm distinguished by the excessive production of red blood cells. The coexistence of these two conditions is exceptionally uncommon and lacks comprehensive documentation. This study presents a case report of a 35-year-old male patient who has been diagnosed with PV for the past 20\u2009years. The patient underwent a radical nephrectomy to remove the renal tumor, and subsequent histopathological analysis confirmed the presence of TC-RCC. Throughout the 6-month follow-up period, the patient exhibited no signs of abnormalities. The rarity of the coexistence of TC-RCC and PV highlights the intricate nature of managing such instances, necessitating a cautious approach to diagnosis and treatment, particularly in surgical interventions. The present study serves as a valuable resource for diagnosing and treating individuals presenting with concurrent renal neoplasms and PV.<\/jats:p>","DOI":"10.1177\/03946320241307777","type":"journal-article","created":{"date-parts":[[2024,12,17]],"date-time":"2024-12-17T00:44:56Z","timestamp":1734396296000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Coexistence
