The incidence of clear cell renal carcinoma corresponds to about 2% of all malignant neoplasms. The classic triad of hematuria, abdominal pain and palpable mass is estimated in 10% of cases. Stauffer described in 1961 the first case called nonmetastatic hepatophrenic dysfunction syndrome, this condition can be found in 3 to 20% of cases. The involvement of liver enzymes may be related to metastatic liver infiltration or also due to non-metastatic dysfunction. It is a rare manifestation in renal cancer. Before the finding of elevated liver enzymes and alkaline phosphatase, ruling out both anatomic and functional hepatic impairment, Stauffer syndrome should be suspected, being able to make the difference between going unnoticed or being a timely finding. This paper reports a little frequent manifestation of paraneoplastic syndrome of clear cell renal carcinoma. [ABSTRACT FROM AUTHOR]

Se presentó el caso clínico de una mujer de 51 años de edad, fumadora inveterada, con antecedentes de anemia de varios años de evolución y trastornos de la personalidad, tratados en ocasiones con fenotiacinas, que comienza a referir desde hace un mes episodios recurrentes, caracterizados por trastornos del estado de ánimo con elementos melancólicos. Estos problemas fueron percibidos por sus compañeros de trabajo, pero sin darle la debida importancia hasta que, en una mañana, la paciente despierta con una hemiparesia izquierda. Se constató por tomografía axial computarizada una imagen de tumoración cerebral valorada por Neurocirugía, y se sometió a tratamiento conservador por parte de dicha especialidad con radiaciones. Mejorado el cuadro, la paciente fue dada de alta con seguimiento ambulatorio hasta que regresa al hospital dos meses después con fiebre de doce días de duración, vómitos en proyectil, cefalea y estado confusional agudo, decidiéndose su reingreso en el hospital militar de Matanzas. La paciente falleció y en la autopsia se constató un adenocarcinoma renal derecho, pobremente diferenciado con metástasis cerebrales múltiples.

Stauffer syndrome is a paraneoplastic syndrome (PS) that involves liver disorders; it has been often related to renal tumors, but also to others such as adenocarcinoma of the prostate (ACP). Our objective was to carry out a systematic review of published cases associated with ACP. A total of 357 articles were accessed, 25 of which met the study's inclusion criteria. All published cases of Stauffer syndrome in patients diagnoses with ACP were in the metastatic stage. The PS resolved in 3 out of 4 patients when ACP-targeted therapy was implemented. The following were identified as poor prognosis factors: the diagnosis of ACP prior to that of SP, non-elevated levels of total bilirubin, and the non-resolution of SP at the start of treatment., (Copyright © 2022 Elsevier España, S.L.U.
