Molluscum Contagiosum
Symptoms
Molluscum presents as small, dome‑shaped, pearly papules with central umbilication. Lesions are usually painless but may itch. They can appear anywhere except the palms and soles, commonly on the trunk, flexural areas, and genital region. Scratching can cause inflammation or secondary eczema around papules. Immunocompromised patients may develop hundreds of lesions.
Cause
A poxvirus infects epidermal cells, leading to characteristic growths. Transmission occurs via direct skin‑to‑skin contact, sexual contact, or contaminated objects like towels. Children, swimmers, and atopic individuals are most at risk. The virus remains localized and does not integrate into host DNA. Immunity gradually develops, leading to spontaneous resolution in many cases.
Treatment
Benign lesions often resolve within 6‑12 months without scarring. Cryotherapy, curettage, or topical cantharidin provides quicker clearance if desired. Imiquimod or potassium hydroxide solutions can be applied at home under guidance. Avoiding shaving over lesions and practicing good hygiene prevent spread. Eczema around lesions responds to topical corticosteroids.
