Overview

Molluscum contagiosum may be classified according to restriction endonuclease analysis into at least two types; type 1 and type 2. Type 1 is more common.

Classification

• Molluscum contagiosum may be classified according to restriction endonuclease analysis into at least two types; type 1 and type 2. Type 1 is more common. There is not enough evidence about correlation of molluscum contagiosum subtypes and the disease features. but there is still no evidence about correlation of virus type to the clinical appearance of the lesions or to their anatomical distribution.

• Molluscum contagiosum also can be categorized based on it's lesions to:
  • Molluscum dermatitis: eczematous patches or plaques surrounding molluscum contagiosum lesions.
  • Inflamed molluscum contagiosum: erythema and swelling of individual lesions, is a clinical finding that may portend a higher likelihood of impending clinical improvement.
