Abstract
- Subepidermal calcified nodule, a subset of calcinosis cutis, is usually presented as single small, raised, hard nodule. Histologically calcium deposition can be detected by von Kossa or periodic acid-Schiff stain. We report a 3-year-old boy who had erythematous hyperkeratotic plaques and papules on both inner thighs without any previous history of trauma, genetic or systemic illness. A biopsy specimen of plaque of the thigh showed the transepidermal elimination of basophilic granules which were dispersed in the upper dermis and von Kossa stain revealed scattered calcific deposition.
