Milia en plaque in a child on the internal canthus

Background. Milia en plaque is nn uncommon skin condition usually seen in a dult women, typically in the retroauricular region. We report a new localiz ation in a young child. Case report. A 6-year-old girl with an uneventful history had developed ove r the last 7 months an erythematous plaque with numerous whitish-yellow mic rocysts on the left internal canthus. No local or general favoring factor w as found. Skin biopsy showed numerous cystic cavities with an epidermal lin ing containing layers of keratin within a moderately inflammatory infiltrat ion. The lesion resolved after enucleation of the cysts and no recurrence h as been ob,cn ed alter 9 months follow-up. Discussion. Milia en plaque is a characteristic erythematous lesion covered with cysts. The usual localization is the rc retroauricular region, but ot her localizations have been reported, mainly on the head. This is the first report involving the internal canthus and also in such a young child. One case of a 15-year-old boy has been described. Milia en plaque is often a pr imary condition as in our case although local or general factors may rarely be inductive. Our case illustrates the different localizations possible fo r milia en plaque, with predominance on the head, and the possibility of ch ildhood cases. We prefer the term milia cn plaque rather than retroauricula r milia en plaque.
