Abstract:
Subepidermal calcified nodule is a rather uncommon, but peculiar subtype of calcinosis cutis. It presents as a single asymptomatic, hard, yellowish white nodule which commonly occurs on the face of children. Histopathologic examination reveals the multifocal various-sized papillary dermal collection of dark blue amorphous globular deposits confirmed by von Kossa stain for calcium. We report a 42-year-old man who had small white hyperkeratotic papule on finger tip for more than 20 years. He could recall neither preceding trauma nor systemic illness. Excisional biopsy, with the clinical impression of verruca or corn, showed typical histopathologic features of the subepidermal calcified nodule.
