Molluscum Contagiosum

Molluscum contagiosum (MC) is a common, self-limiting viral skin infection characterized by the appearance of firm, dome-shaped, flesh-colored or pearly papules with central umbilication. It is caused by the Molluscum contagiosum virus (MCV), a member of the Poxviridae family. While benign, it is highly contagious and spreads through direct contact or fomites.

MC is caused by MCV, a double-stranded DNA virus. Transmission occurs via skin-to-skin contact, sexual contact, or contact with contaminated objects (fomites) such as towels, sponges, or razors. Autoinoculation through scratching is common.

The virus infects the keratinocytes of the epidermis. Replication occurs within the cytoplasm, leading to the formation of characteristic intracytoplasmic inclusions known as Henderson-Paterson bodies. These bodies push the cell nucleus to the periphery, causing the dome-shaped expansion of the lesion. The virus modulates the host immune response to evade detection, often delaying spontaneous resolution.

MC predominantly affects children, sexually active adults, and immunocompromised individuals (e.g., HIV patients). In pediatric populations, prevalence estimates range from 5% to 20%.

• Atopic dermatitis
• Impaired cell-mediated immunity
• Participation in contact sports (e.g., wrestling)
• Crowded living conditions
• HIV/AIDS or immunosuppressive therapy

A. Early Symptoms

• Small, firm, painless papules.


• Mild pruritus. B. Common Symptoms


• Pearly, dome-shaped papules.


• Central indentation (umbilication).


• Size typically 1–5 mm in diameter. C. Advanced Symptoms


• Inflammation or erythema surrounding lesions (Molluscum dermatitis).


• Large, coalescing lesions in immunosuppressed patients. D. Emergency Symptoms


• None; the condition is benign.

Inspection reveals discrete, dome-shaped papules with a central umbilication. When squeezed, a white, waxy, cheese-like substance (curd-like material) can be expressed. Lesions may be distributed anywhere except palms and soles.

A. Clinical Assessment: Based on classic morphology.
B. Laboratory Testing: Rarely required.
C. Imaging Studies: Not indicated.
D. Functional Tests: None.
E. Biopsy Findings: Henderson-Paterson bodies on histopathology.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Verruca vulgaris, varicella, condyloma acuminatum.

Test Name: Viral Culture/PCR
Type: Swab
Purpose: Identify viral DNA
Expected Findings: Presence of MCV DNA
Interpretation: Confirmatory for atypical cases

None standard. Ultrasound may be used rarely if deep involvement is suspected.

• Verruca vulgaris: Lack umbilication, rough surface.
• Condyloma acuminatum: Cauliflower-like appearance, moist sites.
• Basal cell carcinoma: Pearly border, telangiectasia.

Secondary bacterial infection, conjunctivitis (if near the eye), and permanent scarring from aggressive intervention.

A. Lifestyle Modifications: Avoid scratching, cover lesions with bandages.
B. Preventive Measures: Hand hygiene, avoiding sharing towels.
C. Medical Treatment:

• Topical: Cantharidin (blistering agent), Imiquimod (immunomodulator), Podophyllotoxin.

Excellent. The condition is self-limiting, typically resolving within 6–18 months without scarring in immunocompetent patients.

Avoidance of direct skin contact with infected individuals and maintaining good hygiene.
