RESUMEN
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.
RESUMEN
OBJECTIVE: We report the case of a 61-year-old male with the incidental diagnosis of intrathoracic renal ectopia during the workup study for a possible lung mass. METHODS: We performed a bibliographic review on the incidence, origin, clinical presentation and diagnosis of this type of renal ectopia. RESULTS: Chest x-ray showed a left posterior mediastinum mass. Bronchoscopy was performed showing signs of extrinsic compression with absence of neoplastic cells. CT scan revealed a left intrathoracic ectopic kidney with diaphragmatic hernia. CONCLUSIONS: Intrathoracic renal ectopia is a very unfrequent finding, often asymptomatic, frequently an incidental diagnosis that does not require treatment.

Objetivo: Se presenta el caso clínico de un varón de 61 años diagnosticado de manera incidental de ectopia renal intratorácica durante el estudio de posible masa pulmonar. Métodos: Se realiza una revisión bibliográfica de la incidencia, origen, clínica y diagnóstico de este tipo de ectopia renal. Resultados: En la radiografía de tórax se aprecia una masa en mediastino posterior izquierdo. Es practicada una fibrobroncoscopia apreciando signos de compresión extrínseca con ausencia de células neoplásicas. El TAC revela un riñón ectópico intratorácico con hernia diafragmática izquierda. Conclusiones: La ectopia renal intratorácica es un hallazgo muy infrecuente, habitualmente asintomático, diagnosticado con frecuencia de manera incidental y que no suele requerir tratamiento (AU)
