Sometimes periungual wart infections resemble the changes that are found in onychomycosis.

Black puncta, which are microscopic blood vessel-representing dots, frequently form at the core of hyperkeratotic, dome-shaped lesions.

Immunocompromised patients or those with resistant, protracted warts should get a biopsy to rule out high-risk HPV strains, Bowen's disease, and squamous cell carcinoma.

[2][3] Treatment options for warts encompass topical, intralesional, and laser therapy.

Surgical methods include excision and electrodesiccation, which use electrical current to destroy tissue, although they are not recommended as first lines of treatment because of the possibility of scarring and recurrence.
