[Prevalence of arterial hypertension, proteinuria and hematuria in patients with simple renal cyst]. / Prevalencia de hipertensión arterial, proteinuria y hematuria en pacientes con quiste renal simple.

The simple renal cyst (SRC) is a common entity even though its actual incidence is difficult to determine given that it tends to manifest itself in an asymptomatic fashion. Occasionally, cases of SRC with clinical manifestations have been described in the literature, such as arterial hypertension (AHT) and biological alterations such as hematuria or proteinuria. The purpose of this article is to find the prevalence of AHT, proteinuria, and hematuria in patients with SRC detected via echography. 1,197 echographs that explored the renal area--a number equal to that of the number of patients--were reviewed. In 66% of the cases, the echographs were taken for some purpose unrelated to renal pathology. For those who presented SRC, blood pressure, proteinuria per 24 hours, and urine sediment were determined. SRC was detected in 93 patients (7.7%). The prevalence of AHT in patients with SRC was 31%, but 57% of those were older than 85 years. Two patients presented AHT and proteinuria; both fulfilled the criteria for nephrongiosclerosis. Two other patients presented hematuria and proteinuria; one was found to be afflicted with IgA nephropathy and the other with vesical carcinoma. A patient with hematuria was a carrier of renal lithiasis. We conclude that the prevalence of AHT in patients with SRC did not yield a significantly different result from that of the general population. In those patients who presented proteinuria and/or hematuria, one cause was found to be responsible; therefore, the presence of such alterations in patients with SRC should be considered coincidental.

[Adenomatoid tumor of the epididymis: report of a new case]. / Tumor adenomatoide de epidídimo: aportación de un nuevo caso.

We report an additional case of adenomatoid tumor of the epididymis, an uncommon benign intrascrotal tumor. The aspects concerning its embryological origin and the different hypotheses that have been put forward relative to its etiology are discussed.

[Limitations of CAT scan in the diagnosis of myelolipoma of the adrenal gland]. / Limitaciones de la TAC en el diagnóstico del mielolipoma suprarrenal.

The suprarenal myelolipoma is a myeloid tissue and fat tissue tumor. It can undergo degenerative processes of haemorrhage, necrosis and calcification. The diagnostic key is based on the finding of fat tissue in the inside of a suprarenal mass. A CAT would be the method allowing a more accurate diagnosis. Its limitations came from the presence of myelolipomas with abundant myeloid tissue, or which have suffered major degenerative processes in which it is difficult to identify the fat tissue, and in large retroperitoneal masses in which it is impossible to recognize their suprarenal origin.
