All of the following clinical findings are consistent with the diagnosis of molluscum contagiosum EXCEPT
Explanation
ExplanationMolluscum contagiosum is a cutaneous poxvirus infection with a distinctive cutaneous appearance. The rash typically consists of collections of 2- to 5-mm umbilicated papules that can occur anywhere on the body except the palms and soles. It can be accompanied by an eczematous reaction. Molluscum contagiosum is transmitted through close contact, including sexual contact, which causes genital involvement. Unlike other poxvirus lesions, molluscum contagiosum is not associated with inflammation or necrosis. In immunocompetent patients, the disease is usually self-limited; rash will subside within several months. Systemic involvement does not occur.
