Caused by the molluscum contagiosum virus (MCV) which is a member of the pox virus family. The incubation period for MCV is usually 2-3 months. MCV produces flesh-coloured papules which grow over several weeks to a diameter of 3-5 mm. They are smooth, firm and dome-shaped, with a characteristic central umbilication. Occasionally they can grow to 10-15 mm (giant mollus-cum). Papules generally appear on the thighs, the buttocks, the inguinal region and occasionally the lower abdomen. They are less commonly found on the external genitalia or the perianal area.
Adult lice and their eggs can be seen with the naked eye and may appear initially as scabs. Closer visualisation using magnification reveals their true identity. The insects feed on host blood, which they obtain by biting. Patients may present with itching or redness, which is a result of the bites. This reaction varies from person to person. Generally in unexposed people a period of five days can pass before allergic sensitisation occurs, leading to itching, which in turn leads to scratching, erythema, and inflammation. It may be possible also to observe dark-coloured specks on the skin or underwear. There are louse excreta.
