A Case of a Subepidermal Calcified Nodule on the Sole without Trauma

다국어 초록 (Multilingual Abstract)

Subepidermal calcified nodule is an uncommon form of calcinosis cutis, which most commonly occurs in children. It usually presents as an asymptomatic, solitary verrucous nodule on the head and neck region, but occasionally as multiple lesions. Serum calcium and phosphorus levels are usually normal. Histopathology shows well-formed homogeneous eosinophilic material and granules in the upper dermis.
Material in the dermis stained with von Kossa was positive.
We report on an unusual case of a subepidermal calcified nodule occurring on the sole. A 21-month-old male presented with an oval-shaped, whitish, hard nodule measuring 5×5 mm on the left sole, without any previous history of trauma. (Ann Dermatol 23(S1) S116∼S118, 2011)
