What should you know about punch excision gone wrong?

A less-than-ideal appearance does not always mean the procedure was performed incorrectly. Early swelling, crusting, redness and tenderness may change as the wound heals. The concern is whether symptoms are worsening, the wound is opening, or healing is not following the instructions you were given.

Punch excision removes a small, round area of skin and usually leaves a wound that is closed with a stitch or allowed to heal under a dressing. Bleeding can occur if the site is disturbed or a small blood vessel continues to ooze. Infection may cause increasing warmth, swelling, pain, cloudy fluid, or spreading redness.

The edges can pull apart after closure, particularly if the area is stretched or rubbed. The final mark may be wider, darker, lighter, raised, or indented compared with nearby skin. A recurring scar or an incomplete improvement can also reflect the depth, location, or original cause of the treated lesion.

Follow the written wound-care instructions from your treating clinician. Keep the area clean as directed, avoid picking a scab or pulling at a stitch, and protect the site from friction and stretching. Do not apply an antibiotic, antiseptic, acid, steroid, or scar product unless your clinician recommends it for this wound.

If the appearance concerns you, take a clear photograph in good light and contact the clinic that performed the procedure. Tell them when the change began, whether pain or redness is increasing, and what you have applied. Do not arrange scar treatment while the wound is open or infected; the first priority is assessment and safe healing.

Contact your treating clinic promptly for bleeding that continues after firm, uninterrupted pressure, a wound that has opened, increasing pain, worsening swelling, spreading redness, pus-like drainage, fever, or a foul smell. Seek urgent medical help for heavy bleeding, severe swelling, faintness, or symptoms suggesting a serious allergic reaction such as trouble breathing or swelling of the lips and tongue.

If a stitch has become embedded, broken, or is pulling tightly, ask the clinic how it should be managed rather than removing it yourself. A clinician may need to examine the site, clean it, take a swab, prescribe treatment, or discuss later scar care once the skin has closed.

Ask: Does this look like expected healing or a complication? Is the wound infected or separating? Should I change the dressing or stop a product? When should a stitch be removed? If a scar remains, which options are suitable after the wound has healed? Also ask whether the original lesion needs follow-up or laboratory assessment.
