title: Chromophobe renal cell carcinoma associated with eosinophilia: A report of three cases.
abstract: Eosinophilia is typically associated with allergic reactions, parasitic infestations, certain forms of vasculitis, the use of certain medications and hematologic malignancies. In addition to eosinophilia associated with gastrointestinal tumors, lung cancer and thyroid carcinoma in solid malignancies, there are a limited number of cases describing peripheral hypereosinophilia in urologic tumors. The present study reports three cases of eosinophilia in patients with chromophobe renal cell carcinoma (CRCC) and investigates the association between excessive eosinophilia and the recurrence and prognosis of renal carcinoma. This is the first report of CRCC associated with excessive eosinophilia. Eosinophilia following tumor resectioning may indicate a poor prognosis, tumor recurrence and rapid disease progression.
