The small lumps (mollusca) on the skin are not usually itchy, painful, or serious. A scar is not usually left when they go but sometimes a tiny dent or mark remains. In a few people the skin looks lighter in the places where mollusca have been. Occasionally, the skin next to a lump (molluscum) becomes infected with germs (bacteria). This can be treated with antibiotic creams or medicines . Rarely, a molluscum on an eyelid causes eye inflammation. (See a doctor if any eye symptoms develop related to a molluscum.) After an episode of molluscum contagiosum has cleared away, you will normally be immune to the virus and further episodes only occur rarely.
In this condition, the virus reproduces in the cytoplasm of epithelial cells, where it produces cytoplasmic inclusions and enlargement of cells that have been infected. Only the epidermis is infected by this virus. While the magnitude of necessary epidermal damage is not known, the infection spreads from contact with infected persons or contaminated objects. It appears that the initial infection occurs in the basal layer. The period of incubation is normally 2-7 weeks. A latent period of as long as 6 months may follow infection.
