title: [Juvenile colloid milium].
abstract: BACKGROUND
  Colloid Milium is a rare disease. It is characterized by the development, on sun-exposed areas, of clusters of yellow and translucid, hard papules, that seeps a gelatinous substance when opened. This dermatitis predominantly affects elderly patients and, exceptionally, children. We report a case of juvenile colloid milium.
  
  
  METHODS
  A 14 year-old boy consulted for papular, translucid or amber-brown lesions, occasionally hemorrhagic on the cheeks, nose upper lip and the upper edge of the helix of both ears. He was born to consanguineous parents. Living in a rural area, he was exposed to sun during agricultural activities. The lesions had progressed since he was 6 years old and were exacerbated in the summertime. There was no similar case in the family. Histological exploration of a papular lesion showed areas of atrophic epidermis and the presence of a few vacuolized keratinocytes. The epidermis was lifted by nodular lumps of amorphous eosinophilic material deposited in the superficial dermis. Staining with Congo red was negative.
  
  
  CONCLUSIONS
  Juvenile colloid milium is a benign but unesthetic dermatitis. The inducing role of sun exposure is obvious, as in colloid milium of adults, but other pathogenic hypotheses also exist.
