Warts and Verrucae
Diagnosis
Plane warts: usually round, flat-topped, and skin coloured or greyish yellow (common on the backs of hands).
-
Periungual warts are common warts around the nails that can be painful and disturb nail growth — nail biting is a risk factor.
Palmar and plantar warts: grow on the palms and the soles of the feet (verrucae). They often have central dark dots (thrombosed capillaries) and may be painful.
Common warts: firm, raised papules with a rough surface that resembles a cauliflower. Common on knuckles, knees, and fingers. Often asymptomatic but can be tender.
-
Diagnosis is usually made clinically and in most further investigations are not required. If diagnostic doubt, light paring of a wart will reveal tiny black dots on the surface (thrombosed capillaries) but be aware that bleeding may lead to warts spreading.

Management: Advise
-
To reduce transmission - cover with a waterproof plaster when swimming, wear flip-flops or other footwear in communal showers.
Although cosmetically unsightly they are not harmful, usually do not cause symptoms and resolve without treatment
To limit spread - avoid scratching, avoid biting nails or sucking fingers and keep feet dry and change socks daily.

Definition: Cutaneous warts are small, rough growths that are caused by infection of keratinocytes with human papilloma virus (HPV). They can occur anywhere on the body but are common on the hands and feet. A verruca (also known as a plantar wart) is a wart on the sole of the foot.
