Skin distribution Primary milia in term infants commonly are found on the face, especially the nose. They also may be found on the mucosa and palate. Palatal lesions are known as Epstein pearls. Primary milia in older children and adults develop on the face, particularly around the eyes. Secondary milia are found anywhere on the body at the sites affected by the predisposing condition.
Eruptive milia occur on the head, neck, and upper body.
Milia en plaque presents as a distinct plaque in the postauricular area, either unilaterally or bilaterally. Submandibular plaques and lesions on the pinna have been reported. Secondary lesions arise following blistering or trauma, due to disruption of the sweat duct. Milia have been described in many disorders, including bullous pemphigoid, inherited and acquired epidermolysis bullosa, bullous lichen planus, porphyria cutanea tarda, and burns. Skin trauma from dermabrasion can result in milia formation.
