BACKGROUND: @entity2695 ( @entity2695 ) of the kidney is a recently described morphological variant of @entity2695 . It poses a diagnostic dilemma for clinicians because of its rarity and the overlapping features it shares with other @entity703 . The aim of this paper is to review all the cases of @entity8 in the literature. METHODS: The literature was extensively searched for case reports of @entity8 and the clinical and pathological characteristics of the @entity5 were extracted. RESULTS: A total of 45 cases were reviewed. The mean age of presentation was 50 years (range, 15-83 years) and male sex accounted for 68.8% of the cases reviewed. @entity8 was mostly unilateral with only 4 cases of bilateral involvement of the kidney. The average size of the @entity5 is 1.5 cm (range, 0.1-7 cm). Incidental finding of @entity8 accounted for 62% of the cases reviewed. The ultrasound findings demonstrated varying echogenicity and the @entity5 appeared as solid and well demarcated heterogeneous masses on CT. The average follow up of the @entity1 in this review was 26 months (range, 1-156 months). CONCLUSIONS: @entity8 is a rare @entity5 and a morphological variant of @entity2695 . It has a characteristic sinusoidal architecture with a semblance of splenic sinusoids. It has overlapping clinical and imaging features with other @entity5 of the kidney. Histological review and immunohistochemical studies are essential for accurate diagnosis. @entity2695 runs a benign course without evidence of disease recurrence during follow up.
