nested variant of urothelial carcinoma
Large nested pattern of urothelial carcinoma is distinguished from an inverted growth pattern of non-invasive urothelial carcinoma and from von Brunn nests by either MP invasion, irregularly infiltrating nests, or a stromal reaction.
Despite the bland cytologic features of these neoplasms, they have well-documented metastatic potential.
