Micropapillary Histology

Micropapillary histology: a frequent morphology of mutation-associated lung adenocarcinoma?

Non–small cell lung carcinoma is a histologically diverse group of tumors that until recently has been treated homogeneously. As a result, pathologists recognized major classes of squamous, adenocarcinoma, and large cell carcinoma, with subclasses and variants to ensure accurate diagnosis, to identify rare subtypes, to assist pathologist communication, and to create uniformity in research despi...

Micropapillary Variant of Urothelial Carcinoma

Though MPC shows characteristic microscopic features, there exists interobserver variability and also it needs to be differentiated from the metastasis from other organs. The prognosis is generally poor, depending on the proportion of the microp...
