• urothelial cells with jet black chromatin
  6 January 2018

  Urothelial cells with jet black chromatin are mainly tubular cells.
  Some high-grade urothelial carcinomas (UCs) in urine cytology can have jet black, smooth, or glassy chromatin.
  Compared with tubular cells that also often have jet black chromatin, the nuclei of high-grade urothelial carcinoma cells are larger & irregular, have nuclear “points", & have a sickle or half-moon shape.
  Malignant urothelial cells in urine cytology with jet black chromatin are common and can be diagnosed (...)
