Overview
Biopsy
- Patients who have lesions suspected to be melanoma should always be biopsied.
- An excisional biopsy (either elliptical, punch, or sauceritazation) of the thickest portion of the lesion with 1-3 mm margins is recommended.
- Shave biopsy is acceptable only when the index of suspicion for melanoma is low.
- The following should be reported when a biopsy is being reported:
- Location
- Regression
- Tumor infiltrating lymphocytes
- Breslow thickness and vertical growth phase
- Histologic ulceration
- Clark level
- Angiolymphatic invasion
- Neurotropism
- Histologic subtype
