Milia-like Idiopathic Calcinosis Cutis Occurring in a Toddler Born as a Premature Baby

Abstract

Milia-like idiopathic calcinosis cutis (MICC) is characterized by smooth, firm, whitish papules resembling milia. Histologically, it appears as a well-defined, round, basophilic nodule within the upper dermis. Although the etiology and treatment remain unclear, it may resolve spontaneously. Some cases have been associated with Down syndrome, and the mean age of MICC patients was 9.9 years old. Herein, we report a rare case of MICC that was not associated with Down syndrome. Noticeably, the patient, a toddler, was born as a premature baby and had an ischemic injury on the right foot at birth. However, the lesions appeared on both feet, including the non-injured left foot. Otherwise he was healthy. After a 21-month follow-up period, the lesions had almost disappeared without any treatment.

  Fig. 1 (A) Multiple, firm, 1~4 mm sized, whitish papules on the right sole, left heel (arrows), and (B) right 5th toe. Morphologic changes on the right 4th and 5th toes may be caused by ischemic injury at birth.

  Fig. 2 (A) Several focal amorphous basophilic materials in the upper dermis and focal transepidermal elimination of the basophilic materials (H&E, ×40). (B) Von Kossa staining shows reaction of the basophilic materials, which were identified as calcium (Von Kossa stain, ×40).
