1st order laboratory parameters
- Biopsy (tissue sampling) of the lesion: confirm the diagnosis by histology (fine tissue examination) in H/E section (hematoxylin-eosin stain)Note: Preoperatively, the maximum longitudinal diameter of the lesion should be determined.
- Complete resection (complete surgical removal).
Notes on obtaining histology
- Depending on the clinical situation, punch biopsies, shallow ablations (“shave” excisions), or excisional biopsies are appropriate.
- If the clinical picture is clear for squamous cell carcinoma (PEK), complete resection can be performed without prior probing biopsy.
