Molluscum Contagiosum Disease

BASICS

DESCRIPTION
Common, benign viral skin disorder consisting of small umbilicated papules which tend to occur on the face, trunk and extremities in children and on the groin and genitalia in adults. Incubation period is 2 weeks to 2 months. In immunocompromised individuals (e.g., HIV infection), the lesions can be extensive and atypical. They are occasionally giant (up to 3 cm), involve face, neck and trunk, and are recalcitrant to treatment.
  • System(s) affected: Skin/Exocrine
  • Genetics: No known genetic pattern
  • Incidence/Prevalence in USA: Common
  • Predominant age: Children and young adults
  • Predominant sex: Male = Female
SIGNS AND SYMPTOMS
  • Discrete pearly to flesh-colored firm papules
  • Diameter 2 to 6 mm (rarely giant nodules up to 3 cm occur)
  • Usually grouped in one or two areas
  • Centrally umbilicated with erythematous base
  • Lesions can be pruritic or tender
  • Beneath umbilicated center is white curd-like core
  • Distribution: Anywhere. Predilection for face, trunk, and extremities in children and groin and genitalia in adults.
CAUSES
DNA virus of the poxvirus group. The virus cannot be grown in cell cultures. Incubation period is 2 weeks to 2 months after contact.
RISK FACTORS
  • Close personal contact with infected persons
  • In children, transmission can occur from swimming pools
  • In adults, sexual transmission is common
  • Immunocompromised individuals

DIAGNOSIS

LABORATORY

Virus particles cannot be cultured

Drugs that may alter lab results: N/A
Disorders that may alter lab results: N/A

PATHOLOGICAL FINDINGS
  • Intracytoplasmic inclusion bodies in histological or cytological specimens
  • Hypertrophied and hyperplastic epidermis
SPECIAL TESTS

N/A

IMAGING

N/A

DIAGNOSTIC PROCEDURES
  • White, curd-like core easily expressed from beneath umbilication
  • Biopsy

TREATMENT

APPROPRIATE HEALTH CARE

Outpatient

GENERAL MEASURES

Spontaneous resolution common in 6-12 months. Individual lesions resolve in 2 months.

SURGICAL MEASURES
  • Removal by curettage alone, or curettage followed by trichloracetic acid or light electrodesiccation
  • Cryotherapy is also effective
ACTIVITY

No restrictions

DIET

No special diet

FOLLOW UP

PREVENTION/AVOIDANCE

In adults, avoid sexual contact with infected individuals

POSSIBLE COMPLICATIONS
  • Autoinoculation is common
  • Contagious to others
  • Immunocompromised individuals may have extensive infections
EXPECTED COURSE AND PROGNOSIS
  • Untreated, the condition is usually self-limited. Individual lesions spontaneously involute in 2 months. Total resolution usually takes 6 to 12 months.
  • Recurrences are uncommon in immunocompetent individuals
  • Lesions in HIV-infected patients are more recalcitrant

MISCELLANEOUS

ASSOCIATED CONDITIONS

Occurs in 5-18% of patients with HIV infection

AGE-RELATED FACTORS

Pediatric: Commonly seen on face, trunk and extremities. May be spread through swimming pools.
Geriatric: N/A
Others: In adults, is often a sexually transmitted disease.
