The anetodermic ("bullous") subtype is a rare variant of pilomatricoma which we diagnosed in 2 girls who were 9 and 10 years old. The tumors presented as 3 x 2 and 1.5 x 1.5 cm red dome-shaped nodules with a slightly wrinkled surface on the upper back and on the pretibial region, respectively. Both were superficially soft, but then firm as one palpated deeper. Histology showed an edematous, well-vascularized dermis resembling granulation tissue overlying a deep otherwise typical pilomatricoma. Clinical and histological characteristics of the anetodermic subtype are discussed on the basis of previously published cases.
