Molluscum Contagiosum
Molluscum contagiosum, also called water warts, is a benign condition of the skin. The skin lesions of molluscum contagiosum are called mollusca. The typical lesion appears dome-shaped, round, and pinkish-purple in color.
The incubation period ranges from two weeks to six months. Molluscum contagiosum virus infects only keratinocytes, and skin lesions are limited to the epidermis and do not have systemic dissemination. Molluscum contagiosum virus produces proteins inhibiting human antiviral immunity, thus preventing the development of innate immunity response, and contributing to the persistence of skin lesions
