Bethesda The Bethesda System web-based atlas consists of 349 images representing a range of morphologic findings seen on both conventional smears and liquid based preparations. The majority are from cervical specimens; however, some anal-rectal samples are also included.
For each image, the preparation type, morphologic criteria and interpretation using the 2001 Bethesda System terminology are provided. Clinical history, explanatory notes and follow-up are included if available. The database is searchable by keywords, Bethesda System terminology, or Bethesda atlas chapters. There is also a self test of "unknown" images. www.cytopathology.org/NIH
