Molluscum contagiosum

Molluscum contagiosum is a common localized skin infection caused by a poxvirus. The skin lesions are small, waxy-appearing, skin-colored papules with central umbilications. They may appear in clusters or linear distributions from autoinoculation ranging from single papules to hundreds of lesions. While most often seen in children, these lesions can also be seen in sexually active adults or immunocompromised individuals. The virus is transmitted by direct contact with either skin or fomites. They do not have a rapidly evolving appearance in different stages and do not present on an erythematous base like varicella. It is not accompanied by systemic symptoms and are not necessarily associated with pruritis. These lesions often resolve over time, but it may take months to years. Lesions may also be cleared with cryotherapy, curettage, or other topical treatments if they are causing issues.
