A Case of Milia-like Idiopathic Calcinosis Cutis That Improved with Tretinoin Cream / 대한피부과학회지

ABSTRACT

Milia-like idiopathic calcinosis cutis is a rare entity. It is characterized by micronodular, whitish papules resembling milia. Histopathological examination shows small nodular foci of calcium within the superficial dermis, which are surrounded by thick collagen and inflammatory cells. Although the pathogenesis and treatment remain unclear, spontaneous resolution of the lesions may occur. We report a case of milia-like idiopathic calcinosis cutis in a 7-year-old girl who improved after treatment with tretinoin cream.
