Milium consists in the formation of small, whitish or yellowish, rounded, pearly, non-inflammatory elevations situated in the upper part of the corium.
Describe the clinical appearances.
The lesions are usually pin-head in size, whitish or yellowish, seemingly more or less translucent, rounded or acuminated, without aperture or duct, are superficially seated in the skin, and project slightly above the surface.
They appear about the face, especially about the eyelids; they may occur also, although rarely, upon other parts. But one or several may be present, or they may exist in numbers.
What is the course of milium?
The lesions develop slowly, and may then remain stationary for years. Their presence gives rise to no disturbance, and, unless they are large in size or exist in numbers, causes but slight disfigurement.

In rare instances they may undergo calcareous metamorphosis, constituting the so-called cutaneous calculi.
