Connect Sign InAnts in the Pants: Infectious and Inflammatory Lesions of GU Sites
This lecture will review infectious and inflammatory lesions in the genitourinary tract. Topics covered include Schistosoma-associated squamous cell carcinoma, ketamine associated cystitis, syphilis and its increasing frequency, inflammatory myofibroblastic tumor, and angiomyolipoma masquerading as expansile histiocytic inflammation. The implications and prognosis of Schistosoma-associated squamous cell carcinoma is compared to urothelial carcinoma. Ketamine cystitis is a rapidly growing problem with limited clinical recognition and profound impact on bladder health. The continued spread of syphilis across the U.S. has resulted in presentations in non-classical sites and the review covers diagnostic clues. Novel immunohistochemical methods and best practices are suggested for the diagnosis of ALK-positive inflammatory myofibroblastic tumor. Finally, we review a challenging clinical case with histiocytic inflammation nearly completely obscuring a clinically relevant neoplasm, angiomyolipoma.
