*Begins as painless, small [[rash|papule]]

**Central umbilication contains plug of virus-filled white caseous material.
**Can be solitary or multiple
**Can affect any part of the body
***Auto-innoculation can occur and cause genital mollusca<ref name="Zhuang">Zhuang K, Ran Y, Xu F, Lama J. Atypical infantile genital Molluscum contagiosum. Anais Brasileiros de Dermatologia. 2015;90(3):403-405. doi:10.1590/abd1806-4841.20153298.</ref>

==Differential Diagnosis==
{{Peds Rash DDX}}

==Evaluation==
*Clinical diagnosis, based on history and physical examination
*Biopsy with histology can confirm diagnosis if unclear

==Management==
*Hygiene is key to reduce spread
**Ensure adequate hand-washing
**Wash all clothes in warm water
**Avoid touching the area
**Avoid sharing towels or clothing
*Self-limited - no specific treatment necessary
**Lesions resolve within 6-18 months in immunocompetent patients<ref name="Nadhini" />
**Treatment may be warranted in immunocompromised patients, for cosmesis, or to prevent autoinnoculation
*Treatment options<ref name="Nadhini" />
**Cryotherapy - liquid nitrogen, dry ice
**Scrub with betadine or retin-A 0.025% gel for 5 minutes daily
**Surgical excision/curettage (may cause scarring or spread of lesions) <ref name="Bode">Sara Bode; Contagious Exanthematous Diseases. ''Quick References 2022''; 10.1542/aap.ppcqr.396150</ref>
**PO antivirals (e.g. Cidofovir)
**Cantharidin (blister beetle extract) or imiquimod cream are off label options <ref name ="Bode"/>
