title: Unilateral colloid milium: a rare presentation.
abstract: We report a case of a 31-year-old man with asymptomatic papules on one side of his face that had been present for 31 months. On physical examination, he had clusters of 1 to 4 mm skin colored translucent and dome-shaped, papules forming a plaque with a size of 4 x 3 cm on his left mandibular angle. Histopathology revealed atrophy of the epidermis with extensive deposition of pale eosinophilic homogenous deposits containing artifactual fissures that were PAS positive, diastase resistant, and Congo red negative. The final diagnosis was unilateral colloid milium.
