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.
What This Service Includes
Diameter choice
3 vs 4 mm punch based on lesion size and cosmetic area.
Hemostasis

Wound care
Petroleum ointment, bandage, watch infection signs.
What to Expect
Mark & prep
Lesion center aligned; local anesthetic bleb.
Core specimen
Down to subcutis when required; lift specimen without crush artifact.
Close or dress open
Suture or secondary healing per defect geometry.
Frequently Asked Questions
Small punches often flatten with healing; larger cores may leave a subtle divot—discussed beforehand.
Shave samples epidermis/superficial dermis; punch captures deeper architecture for uncertain lesions.
We balance diagnostic urgency with scar risk—sometimes refer to dermatology for high-risk facial lesions.
Usually similar to excisional specimens—1–3 weeks depending on lab.
