Diagnosis: Molluscum Contagiosum
Diagnosis: Molluscum Contagiosum Findings: Shiny dome-shaped papules often with central umbilication (depression) Most commonly skin-colored or pinkish, though may also be hypopigmented or hyperpigmented In adults, it is most commonly spread through sexual transmission, and thus found in groin or genital area In children, most commonly NOT found in the groin or genital area Key [ ]
Diagnosis: Molluscum Contagiosum Findings: - Shiny dome-shaped papules often with central umbilication (depression) - Most commonly skin-colored or pinkish, though may also be hypopigmented or hyperpigmented - In adults, it is most commonly spread through sexual transmission, and thus found in groin or genital area - In children, most commonly NOT found in the groin or genital area Key teaching points: - Molluscum contagiosum is caused by a virus, specifically a poxvirus - It is spread through direct contact or through sharing of items such as towels. In adults, it is most commonly spread by sexual contact. - More common in young children, and less frequently in older children and adolescents - Usually diagnosed through visual examination, though if needed, a biopsy or smear of the contents may be performed - Treatment may include: no treatment, topical treatments such as cantharidin (blistering beetle juice), cryotherapy (cold spray), or scraping the spot. In the US, molluscum
Flesh-colored, dome-shaped papules with central dell in children or sexually active adults. Distribution: trunk, extremities, face in children; genital area in adults.
Observation (self-limited). Curettage, cryotherapy, cantharidin. Topical: imiquimod (off-label), topical retinoids. In immunosuppressed: treat underlying condition, cidofovir for refractory cases.
• Verruca vulgaris • Basal cell carcinoma (small) • Milia • Cryptococcosis (immunocompromised) • Histoplasmosis (immunocompromised) • Folliculitis • Keratoacanthoma
• Caused by Molluscum contagiosum virus (MCV) — a poxvirus • Pearly, dome-shaped papules with central umbilication are pathognomonic • Self-limited in immunocompetent patients (6-12 months), but may persist for years • Widespread or giant lesions in HIV → check CD4 count • Eczema molluscatum: molluscum in areas of atopic dermatitis • BOTE sign (beginning of the end): surrounding dermatitis/inflammation heralds spontaneous resolution • Histology: Henderson-Patterson bodies (eosinophilic cytoplasmic inclusions)
