Abstract

Aims: To describe the histopathological features of a series of patients with ketamine-related cystitis. Methods and results: Seventeen patients with ketamine-related cystitis, who had undergone biopsy, were identified and reviewed. Twelve showed ulceration with significant urothelial atypia. In 10 of these, immunohistochemistry was performed; 9/10 had high p53 immunoreactivity and 7/10 had moderate to high levels of Ki67 reactivity, but all were negative for cytokeratin 20. Conclusions: Ketamine can lead to reactive urothelial changes that can mimic carcinoma in situ, but the long-term cancer risk remains unknown. Journal compilation
