Primary milia in infants typically appear as 1-2 millimeter bumps around the nose, eyes, cheeks, chin, and forehead. They can also appear on the trunk, legs, arms, penis, and mucous membranes.
Milia can occasionally be seen in the mouths of infants and are called Epstein pearls in this event. Sometimes, milia can be present with other skin conditions such as baby acne.
In other age groups, milia can appear similar to several other skin conditions. These include certain moles and cancers, as well as the following:
- Cysts - fluid-filled nodules.
- Comedones - skin-colored papules seen in acne.
- Xanthelasma - lesions containing a buildup of fat within the body's immune cells, which is sometimes associated with high cholesterol levels.
- Syringomas - benign sweat duct tumors.
- Seborrheic keratosis - warty spots commonly associated with aging
