Warts

A cutaneous wart is a human papillomavirus infection of epidermal keratinocytes. The raised, rough lesion is the visible output — not the whole of it.

Mechanism

What is actually happening

HPV drives keratinocyte proliferation. Destroying the visible lesion does not remove virus from surrounding skin that still looks normal, which is why recurrence is the number that matters.

The distinction

How it is told apart

Not everything rough and raised is a wart. Seborrhoeic keratoses, corns and calluses on weight-bearing skin present similarly and are managed differently.

Assessment

What is established first

Site, number, thickness, duration, prior treatment and immune status. Hand and foot lesions behave differently from one another.

Approach

What is typically done

Cryotherapy, electrocautery, laser and acids all remove the lesion. Interval between sessions materially affects recurrence. Immunotherapy is used where lesions are refractory.

When treatment waits

When it is deferred

Picking or shaving over warts spreads virus. Long-standing lesions become more resistant. Immunosuppression changes both clearance and recurrence.
