Micropapillary urothelial carcinoma (abbreviated MPUC), also micropapillary urothelial cell carcinoma (abbreviated MPUCC), is an aggressive variant of urothelial carcinoma.[1]
General

Features:[1]
- Micropapillae.
- Quantity of micropapillary (percentage) is variable.[2]
- Conventional urothelial carcinoma (typical).
DDx:
- Metastasis (breast, ovary, lung, pancreas, salivary gland).
