A 5-year-old boy presents with multiple, asymptomatic facial “bumps” of recent onset.
Key point: The globoid-shaped papules with central umbilication are typical for molluscum contagiosum, a pox virus infection spread by skin-to-skin contact.
Treatment: Sharp curettage removes lesions nicely. Light liquid nitrogen cryospray may also be effective in some patients. When surgical intervention is impractical, topical application of various irritants (such a tretinoin or salicylic acid) or immune modifiers (such as imiquimod) may be effective.
Note: The same disorder may occur in adults, usually in the genital region, as a sexually transmitted disease. Treatment options are the same.
