Mollosum has a lot in common with warts. However, molluscum lesions are smaller, have a central dimple, and appear in groups.
Lesions are usually clustered in groups – anything from 2 to over 30. Numerous small ones may be very close to each other and look like a funny sort of rash. Time to get the magnifying glass out. The lesions are usually smaller than viral warts (1 to 6mm across) and are classically described as “dome shaped” . Take a close look at the top of each lesion and you’ll often see a small dimple.
They are skin-coloured, pink, red or brown, and are often a little shiny.
They do have a fairly typical appearance to the experienced eye.
Individual lesions clear up after a few weeks – often to be replaced with lesions elsewhere. As individual lesions start to clear up, they often become inflamed and may even look infected although secondary infection is rare. A different phenomenon is when the background skin becomes scaly. The virus causes a localized eczema in around 10% of people. It’s also worth knowing that molluscum is more common and often more abundant in kids who have eczema. It can then be quite severe.
Molluscum can occasionally be up to 1.5cm. A solitary giant molluscum in an adult may look like a skin cancer, and a skin biopsy will likely be required.
