Abstract

To the Editor.—  Subepidermal calcified nodule (SCN) was first defined by Winer1 in 1952 and named by Woods and Kellaway2 in 1963. It presents as solitary3 or multiple2,4 nodules, most often occurring on the head or extremities. An SCN is more common in children and may be congenital1 or acquired.2-4 The oldest patient described was 56 years of age. Clinically, the lesions present as hard, verrucous, domeshaped papules or nodules that may appear white or yellowish white, and occasionally resemble milia. Histologically, there is extensive deposition of calcium in the dermis as granules, nests, or large masses.3We present an unusual case of SCN in an octogenarian that presented as a large verrucous tumor on the knee.

Report of a Case.—  An 87-year-old woman was seen in consultation for an asymptomatic flesh-colored nodule on the left knee during hospitalization to evaluate cognitive deficits
