Description
Summary:Colloid milium is a rare cutaneous deposition disorder characterized by the presence of asymptomatic multiple dome-shaped semi-translucent waxy yellowish or skin-colored papules. It is commonly seen on the face and dorsum of forearms and arms due to chronic sun exposure. Nodular amyloidosis and primary systemic amyloidosis mimic adult colloid milium more closely. They share indistinguishable common features clinically and histologically. Purpura following trivial injury is a cardinal feature of primary systemic amyloidosis. Here, we are reporting a case of adult colloid milium, presented with waxy papules and purpura involving the dorsa of the lower half of the forearms and hands which is confirmed by histopathological and immunohistochemical studies.
