Colloidal miliaria

This disease is also called colloid pseudomilium or cutaneus colloid degeneration. It has been translated as a colloidal glioma or a glial miliaria. First reported by Reuter and Way in 1942. The rash occurs on the face and back of the hand. Most of the rashes are round, translucent, flat papules that are pale yellow in size, from millet to lentils, much like blisters. After sticking with a needle, a sticky gel-like substance can be extruded.
