Typically, the lesion of molluscum begins as a small, painless papule that may become raised up to a pearly, flesh-colored nodule. The papule often has a dimple in the center. These papules may occur in lines, where the person has scratched. Scratching or other irritation causes the virus to spread in a line or in groups, called crops.

The papules are about 2 - 5 millimeters wide. There is usually no inflammation and subsequently no redness unless you have been digging or scratching at the lesions.

The skin lesion commonly has a central core or plug of white, cheesy or waxy material.

In adults, the lesions are commonly seen on the genitals, abdomen, and inner thigh.

Diagnosis is based on the appearance of the lesion and can be confirmed by a skin biopsy. The health care provider should examine the lesion to rule out other disorders and to determine other underlying disorders.
