Atrophic Kidney-Like Lesion - Case Report of A Provisional Entity with Brief Review of Literature

Abstract

Atrophic kidney-like lesion is a recently recognized entity, post 2016 World Health Organization Classification of tumors of the urinary system. The behavior of this tumor is not fully known as only a handful of cases with limited follow-up are available. This entity closely mimics thyroid-like follicular carcinoma of the kidney, which has different prognosis. We report a case of incidentally detected atrophic kidney-like lesion in an elderly gentleman who had urothelial carcinoma of the urinary bladder with a brief review of literature. Atrophic kidney-like lesion and urothelial carcinoma of the urinary bladder association has not been reported in the literature.
