Characteristic shape of Molluscum contagiosum infection

A 4-year-old preschooler presents with the skin lesions shown here. The area affected is just below the chin on the child's right side. The lesions have been present over the last month, and the child has reported no symptoms associated with them. The most likely diagnosis is

  • A) varicella
  • B) herpes zoster
  • C) Rhus dermatitis
  • D) molluscum contagiosum
  • E) scabies

 The answer is D. (Molluscum contagiosum) 
Molluscum contagiosum is a common, superficial viral infection of the skin that typically occurs in infants and preschoolers. The incidence decreases after the age of 6 to 7 years. The condition can be spread via sexual contact in young adults.
The lesions are dome-shaped, waxy, or pearly-white papules with a central white core and are 1 to 3 mm in diameter. Frequently, groups of lesions are found. The lesions may resolve spontaneously. Treatment involves removal with a sharp needle or curette, application of liquid nitrogen, antiwart preparations, electrodessication and curettage, or trichloroacetic peels for extensive areas. Typically, infants or young preschool-age children should not be treated aggressively.
