  Definition: Low-grade papillary urothelial carcinoma is a papillary urothelial neoplasm with some degree of cytoarchitectural disorder and distinct but low grade cytologic abnormality.

  Micropapillary urothelial carcinoma of the bladder
  Invasive micropapillary carcinoma is the name given to a distinctive pattern of carcinoma characterized by cleft formation around neoplastic cell clusters.
  Tumors with this morphology, even when focal in otherwise conventional carcinoma, are characterized by a high degree of lymphotropism.
  Electron microscopy examination in a handful of invasive micropapillary carcinoma cases demonstrated an unexpected secretory activity in the (...)
