Molluscum Contagiosum

molluscum contagiosum

DEFINITION AND CLINICAL FEATURES 
Benign papules caused by a poxvirus that present
as shiny, umbilicated, slightly translucent, pink or
skin-coloured papules. They grow slowly, usually
being less than 1 cm in diameter 
Lesions can occur at any site, usually on the head,
neck, and flexures; they are more widespread and
larger in immunosuppressed patients and those
with HIV infection. Rarely, grouped lesions can
form large plaques. The infection mainly occurs
in childhood, but may be sexually transmitted
in adults.
DIFFERENTIAL DIAGNOSIS
Solitary giant lesions can be confused with a wide
variety of lesions including keratoacanthoma,
basal cell carcinoma, and viral warts.
INVESTIGATIONS
None routinely necessary. Histology of lesions
shows diagnostic changes. Consider HIV testing
in adults with widespread infection.
TREATMENT
Treatment is usually not necessary as the infection
is usually self limiting. Troublesome lesions can
be treated by curettage, cryotherapy, or by gently
expressing or disrupting the contents.
