Description
Summary:Squamous metaplasia is a proliferative lesion characterized by the replacement of the transitional epithelium with stratified squamous cells. In the urinary system, it is mostly seen in the bladder. It can be nonkeratinized or keratinized. We report the cases of 2 adolescent girls with keratinizing metaplasia, 1 of whom presented with difficulty with indwelling catheterization and 1 with final terminal hematuria. The predisposing factors were recurrent urinary tract infection and additional catheterization in 1 of the patients. The diagnosis was confirmed by histologic examination in both patients. We report on these cases to draw attention to this rare entity in children.
