Oncocitosis renal de paciente en hemodialisis

Abstract

Objetivo: La oncocitosis renal es una patología infrecuente. Presentamos el primer caso publicado de paciente diagnosticado de esta patología y sometido posteriormente a trasplante combinado riñón-páncreas. Métodos: Presentamos el caso de un paciente en el que, en una revisión rutinaria por Insuficiencia Renal Crónica Terminal (IRCT) y tratamiento con hemodiálisis, en espera de trasplante renal, se diagnostican de forma incidental dos oncocitomas renales y focos de oncocitomatosis microscópica. Se realiza nefrectomía radical derecha y tras el estudio anatomo-patológico, con masas dominantes caracterizadas como oncocitomas renales (OR), se sometió a trasplante combinado reno-pancreático nueve meses después. Resultados: El postoperatorio cursa sin incidencias. Tras un seguimiento de tres años el paciente no ha mostrado recidiva de su patología oncocítica, y el injerto es normofuncionante. Conclusiones: La presencia del antecedente de IRCT en tratamiento con hemodiálisis en los pacientes con oncocitomatosis renal es llamativa, no quedando establecida la causa de esta relación. El tratamiento al que se someta el paciente para la oncocitosis renal y las características anatomopatológicas presentes en el espectro de esta patología condicionarán cuando es posible la realización de un trasplante renal en este tipo de enfermos, y condicionará el pronóstico. Es aconsejable el seguimiento de los pacientes a largo plazo, dada la posibilidad de afectación metacrónica o bilateral, y la asociación entre oncocitomatosis renal (OCR) y carcinoma de células renales (CCR) hasta en un 32%.

Objective: Renal oncocytosis is a rare pathology. We report the first case published of a patient with this disease undergoing combined pancreas-kidney transplantation. Methods: We report the case of one patient with end stage chronic renal failure receiving hemodialysis with the incidental diagnosis of two renal oncocytomas and microscopic oncocytomatosis in a routine revision while awaiting for renal transplantation. Right radical nephrectomy was performed with the pathologic diagnosis of renal oncocytomas. The patient underwent combined kidney-pancreas transplantation nine months later. Results: The postoperative course was uneventful. After three years of follow-up the patient has not shown recurrence and the graft has normal function. Conclusions: The presence of the antecedent of end stage renal disease under treatment with hemodialysis in patients with renal oncocytomatosis is striking, but the causative relationship is not established. The treatment for renal oncocytosis and pathologic characteristics present will condition when will be possible the performance of a kidney transplant in these patients, and will also condition prognosis. Longterm follow-up is recommendable due to the possibility of metachronic or bilateral involvement, and the association between renal oncocytomatosis and renal cell carcinoma in up to 32% of the cases.
