Characteristic shape of Molluscum contagiosum infection

• A) varicella
• B) herpes zoster
• C) Rhus dermatitis

 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.
