Colloid milium (CM) is the deposition of amorphous material in the dermis and is typically seen after many years of sun exposure.
- Men seem to be preferentially affected 4:1.
- The prevailing opinion is that the colloid is derived from elastic fibers undergoing actinic degeneration. Long-term exposure to petrolium derivatives has been linked to CM.
- See also juvenile colloid milium.
The typical lesions are many 1-5 mm discrete, amber, translucent papules on the face, neck, ears and dorsal arms and hands in a fair-skinned patient with many years of sun exposure. The skin may appear thickened or furrowed. A report of two taxi drivers with isolated left arm exposure (sun) has been published.
Treatment is limited. Limiting future sun exposure is important. Dermabrasion has been done.
