Punch biopsy balances diagnostic yield with cosmesis on cosmetically sensitive areas. The American Academy of Dermatology outlines why biopsies matter in pigmented lesion workups. In Canada, dermatopathology services interpret specimens; we orient the specimen for epidermis marking if lateral margin assessment matters.
Punch sites heal by secondary intention or single suture depending on size and tension.
