A Study of a Patient with a Subepidermal Calcified Nodule on the Sole / 대한피부과학회지

ABSTRACT

Subepidermal calcified nodule is a rare form of calcinosis cutis, which is not associated with any dermatologic or systemic diseases, and usually presents as a solitary hard nodule on the face or neck of children. A 25-month-old boy had a small pea-sized, tender nodule on his left sole that had been present for several months. There was no history of previous trauma or systemic illness. The clinical diagnosis as a viral wart was initially made and treated with cryotherapy. Because the lesion was not clear and a yellow-white firm papule was seen after cryotherapy, punch excision was done. Histologic examination showed cystic structure with calcium deposition in the upper dermis. Herein, we present the findings of a patient with a rare, solitary subepidermal calcified nodule on the sole.
