Primary Malignant Fibrous Histiocytoma of the Kidney

Abstract: Primary renal malignant fibrous histiocytoma is a rare tumor of the kidney. It is clinically and radiologically indistinguishable from a renal cell carcinoma. Even following radical surgery, the tumor shows a strong predilection for local recurrence and the prognosis is generally poor. We report on a 32-year-old man with malignant fibrous histiocytoma of the kidney who remained free of recurrence for 1 year after radical nephrectomy.

“…An abdominal mass and hematuria may be evident but are less common. In contrast, these symptoms are seen in renal cell carcinoma and preoperative differentiation can be difficult [37] . However, selective renal arteriography usually reveals a hypovascular tumor as compared to renal cell carcinoma [38] .…”

“…To date, there are only 54 reported cases of MFH arising from kidney [37,38] . The other reported sites of MFH occurring in the genitourinary system are the urinary bladder, prostate and spermatic cord [39][40][41][42] .…”

“…El más común de estos tumores es el leiomiosarcoma, que representa entre el 40% y 60% de los casos publicados 2,3 . El SIP, antes llamado fibrohistiocitoma maligno pleomórfico 5,13 , es una variante inusual, con alrededor de 60 casos publicados en la literatura mundial, la mayoría del siglo pasado, no encontrando en la revisión bibliográfica reportes nacionales 1,7 . No existen criterios definidos para el diagnóstico de sarcoma renal primario, sin embargo se sugieren los siguientes: 1) no tener antecedentes de sarcoma en otra localización anatómica (exclusión de metástasis); 2) un estudio macroscópico que demuestre el origen renal de tumor; 3) la exclusión del diagnóstico de carcinoma renal de patrón sarcomatoide; y 4) de existir una metástasis, esta debe ser más pequeña que el tumor renal 2,13,14 .…”

“…El riñón más afectado es el izquierdo 1 , a diferencia de nuestro caso, que fue el derecho. Los SIP renales son de gran tamaño y presentan características similares a los sarcomas de partes blandas: son multilobulados, de color amarillo grisáceo, pobremente encapsulados, con extensas áreas de hemorragia y necrosis 7,13 . Microscópicamente se caracterizan por presentar células fusiformes muy pleomórficas, multinucleadas, que se entremezclan con fibroblastos y macrófagos 13,18 .…”
