Conservative management of unusual keratinising squamous metaplasia of the bladder in a 28-year-old female and overview of the literature. Case Rep Urol; 2012:940269http://hdl.handle.net/10668/808Journal Article;Keratinizing squamous metaplasia of the bladder is rare and is usually associated with urinary tract infections and chronic irritation. It is considered a precancerous condition of squamous cell carcinoma, especially when more than 50% of the bladder surface is affected. Medical treatment cannot eradicate this lesion. When it is limited to a small area of the bladder, transurethral resection is possible. Annual cystoscopy with multiple biopsies as well as annual upper tract imaging is proposed in the follow up of these patients. We present a preliminary 2-year followup report of a keratinizing squamous metaplasia of the bladder in a 28-year-old female patient with no previous risk factors.enMetaplasiaVejiga UrinariaCarcinoma de Células EscamosasAdultoCistoscopíaBiopsiaProgresión de la EnfermedadLesiones PrecancerosasUrografíaFemeninoMedical Subject Headings::Diseases::Pathological Conditions, Signs and Symptoms::Pathologic Processes::MetaplasiaMedical Subject Headings::Anatomy::Urogenital System::Urinary Tract::Urinary BladderMedical Subject Headings::Diseases::Neoplasms::Neoplasms by Histologic Type::Neoplasms, Glandular and Epithelial::Carcinoma::Carcinoma, Squamous CellMedical Subject Headings::Named Groups::Persons::Age Groups::AdultMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Urological::CystoscopyMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Clinical Laboratory Techniques::Cytological Techniques::Cytodiagnosis::BiopsyMedical Subject Headings::Diseases::Pathological Conditions, Signs and Symptoms::Pathologic Processes::Disease Attributes::Disease ProgressionMedical Subject Headings::Diseases::Neoplasms::Precancerous ConditionsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Imaging::Radiography::UrographyMedical Subject Headings::Check Tags::Femaleresearch article22830070open access10.1155/2012/9402692090-6978PMC3399369
