Periungual wart - Nail and Distal Digit
Warts involving the nails are fairly common in children. Warts of all kinds reach their peak prevalence in childhood and adolescence. Risk factors include atopic dermatitis, immunosuppression, nail biting, and nail picking.
In adults, warts are especially common among transplant patients and in individuals immunosuppressed due to human immunodeficiency virus infection (HIV), malignancy, or medications. They are also common in adults who do wet work, as well as in nail biters and nail pickers. There is a subset of ungual warts due to HPV 16 and 18 that are at higher risk of transforming into squamous cell carcinoma.
