Molluscum contagiosum appears as a rash composed of pink or flesh-colored bumps anywhere on the skin, according to the American Academy of Dermatology. Usually, there are only 10 to 20 bumps, but people with compromised immune systems, such as those with HIV, may have 100 or more bumps.
The bumps begin as small, painless nodules that may become raised and appear as pearly, flesh-colored nodules, explains MedlinePlus. There is often a dimple in the center of the nodule, and the core contains a white, waxy or cheesy material. Normally, there is no surrounding inflammation unless scratching occurs. When scratched, the rash spreads in a line or in groups called crops. In adults, this viral infection often occurs on the genitals, inner thighs and abdomen.
