Objectives:
We report a new case of squamous metaplasia because of its interest and subtle differential diagnosis with other bladder pathologies.
Methods:
We report the case of a male patient with history of previous neoplasia with an exophytic lesion of the bladder wall discovered on follow-up. Pathological diagnosis after TUR was bladder squamous metaplasia.
Results:
Follow-up is performed by ultrasound, cystoscopy, and urine cytology in adherence to clinical guidelines due to the possibility of transformation into squamous cell carcinoma.
Conclusions:
Urothelium is able to develop non neoplastic transformations such as squamous metaplasia. The importance of such transformations depends on proper diagnosis and follow-up due to their ability to transform into a neoplastic process.
