Figure 1. A small, pink, firm papule with a rough scaly surface and peripheral erythema located on the right superior helix of a 7-month-old boy. Figure 2. Hemotoxylineosin stain revealed a defect of the epidermis with underlying fibrin deposits (original magnification,×20). Figure 3. Subjacent to the ulcer, there was chondroid tissue, granulation tissue with prominent vascularity, and an extensive amount of amorphous calcified material throughout the dermis extending to the base of the specimen (hemotoxylineosin stain; original magnification, ×100).
