Abstract

Biopsies from the urinary bladder are challenging and it may be difficult to differentiate normal from benign or reactive processes, and even from low-grade neoplastic processes. This chapter addresses these common problems by profiling immunohistochemical stains that change their patterns of expression from that of normal urothelium, including both the cellular layers and cellular compartments in which markers are expressed. Morphologic patterns of urothelial carcinoma that cause diagnostic dilemmas are also included, such as glandular lesions of both primary and metastatic origin, and lesions with variant histologic growth patterns. Staining patterns of urachal neoplasms and their differential diagnoses are addressed. Nephrogenic adenomas of the urothelial tract and their mimics are covered. Although uncommon, the differential diagnosis of spindle cell lesions is also addressed.
