RESUMO
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.

Milia-like idiopathic calcinosis cutis (MICC) is a peculiar subtype of idiopathic calcinosis cutis, characterized by clinically resembling milia, and the majority of the cases are associated with Down syndrome. We report a rare case of MICC which was not associated with Down syndrome. A healthy 10-year-old boy presented with whitish papules surrounded by erythema on the back. Some of the papules were umbilicated or crusted, therefore, they gave a clinical impression as molluscum contagiosum. Histopathologic findings of the papule showed calcium deposits as amorphous, basophilic mass on the upper dermis and focal transepidermal elimination of calcium, which were compatible with MICC.

Down syndrome is associated with a large number of abnormal skin features including syringoma. Milia-like idiopathic calcinosis cutis is one of the rare dermatoses associated with Down syndrome. It has been reported in children with Down syndrome and clinically suggested as milia. The histological features show small nodular foci of calcium within the papillary dermis and transepidermal elimination of calcium deposits occasionally. We describe a 14-year-old female affected by Down syndrome, who had whitish papules on both the dorsal hands and feet and periorbital syringomas. Histopathological findings of the papule on the dorsal hand showed calcium deposits as amorphous, basophilic masses in the upper dermis and focal discharge of calcium by means of transepidermal elimination.
