Laboratory parameters 1st order
- Histology (fine tissue examination) from sample excision (tissue removal) or total excision (surgical removal of the tumor as a whole) [examination on HE(hematoxylin-eosin)-stained specimen].
- Note: Trial biopsy required only if:
- Suspected tumor type with high risk of recurrence (risk of disease recurrence; infiltrative, sclerodermal, micronodular, metatypical).
- Superficial (“superficial”) basal cell carcinoma (sBZK; synonyms: trunk skin basal cell carcinoma; trunk skin BCCs) before a “blind” therapy procedure (topical therapy).
- Pigmentation – due todifferential diagnosis of malignant melanoma; excisional biopsy should be considered here.
- Clinical diagnosis not clear, so that differential diagnoses must be excluded.
Laboratory parameters 2nd order – depending on the results of the history, physical examination, etc. – for differential diagnostic clarification.
- Small blood count
- Differential blood count
- Inflammatory parameter – CRP (C-reactive protein)
