[Purple Urine Bag Syndrome and Penile High-Grade Dysplasia: A Rare Clinical Intersection].

Purple urine bag syndrome (PUBS) is an uncommon phenomenon characterized by the purple discoloration of urinary catheter bags. We present a unique case of an 81-year-old male with a history of acute ischemic stroke, initially presenting with a cauliflower-like growth on the distal part of the penis. Subsequent assessment revealed a high-grade dysplasia lesion. During the preparation for partial penectomy, the patient developed PUBS. Urine culture indicated a mixed growth of organisms, promptly treated with intravenous cefuroxime, resulting in the resolution of the purple discoloration. The patient underwent successful partial penectomy and was discharged without complications. This case highlights the rare co-occurrence of PUBS and high-grade dysplasia, emphasizing the importance of comprehensive management in such complex clinical scenarios.
