Subepidermal calcified nodule - Skin
The typical clinical presentation is a solitary, verrucous papule or nodule on the head or neck in an otherwise healthy child. The majority of lesions are first noted by parents within the first two years of life, if not at birth. The largest case series found a 2:1 male predominance. Lesions are almost invariably painless. The pathogenesis is unknown. SCN is frequently misdiagnosed as far more common entities such as verruca vulgaris, molluscum contagiosum, or epidermal inclusion cysts.
