Diagnostic pitfalls and considerations

  • Fibrotic change due to recent radiotherapy can make it difficult to obtain a cellular sample. Iatrogenic changes must also be taken into consideration.
  • If only a small amount of sample is aspirated into the needle, then syringe the sample straight onto the slide and advise application of suction maybe required on the next pass.
  • Necrosis / sufficient viable material for effective p16 testing.
  • In cases where lymphoma is suspected or low-grade lymphoma can not be excluded on cytology alone. Then a biopsy maybe required (dependant on local protocol for lymphoma typing).
