Molluscum contagiosum - Management
How should I diagnose molluscum contagiosum?
- Molluscum contagiosum is a clinical diagnosis. The appearance of lesion(s) allows other conditions to be excluded (for example warts). Lesions do not usually cause symptoms, unless they become inflamed or develop an eczematous reaction. Diagnostic investigations are not necessary.
- Typically, the person presents with lesions which have developed over a few weeks:
- Lesions are pinkish or pearly white papules with a central umbilication, and are up to 5 mm in diameter. For images, see www.dermis.net.
- Lesions appear in clusters in areas anywhere on the body (except the palms of the hands and the soles of the feet):
- In children, lesions are commonly seen on the trunk and in flexures, but anogenital lesions may also occur.
- In adults, sexual contact may lead to lesions developing on the genitalia, pubis, thighs, and lower abdomen.
- Rarely, lesions can occur on the oral mucosa and on the eyelids.
- Immunocompromised people (e.g. with HIV) or people on immunosuppressants (e.g. corticosteroids) can present with atypical lesions (e.g. larger, more widespread, and numerous [possibly up to 100] lesions).
