Abstract:
Colloid milium is a rare cutaneous condition with at least three distinct subtypes, characterized clinically by the development of yellowish translucent papules or plaques on sun-exposed skin, and histologically by the presence of colloid in the dermal papillae. In this case report, we present a man with multiple small papules on dorsum of his hands that in pathology confirmed to be colloid milium. Colloid milium is more commonly observed in fair-skin patients and remain unchanged; however our patient had dark skin type (Fitzpatrick skin type III) and lesions were increasing in summer and decreasing in winter.
