[Value of LDH in the diagnosis of pseudocystic renal cancer]

Abstract

An asymptomatic case of cystic renal carcinoma is presented. The only diagnosis of certainty was given by a marked increase in L.D.H. levels in the fluid of the tumor after puncture. The pros and cons of imaging studies, and the relative lack of value of aspiration cytology when negative results are encountered are discussed. The pathological anatomical findings of the nephrectomy sample certified the diagnosis, showing the presence of a pseudocystic adenocarcinoma due to intratumor necrosis.
