Petrified auricle with ectopic ossification and trans- epidermal elimination of bone sequester: A case story and review of the literature

Abstract

Petrified auricle is a clinical condition in which parts of one or both auricles become rigid and stony hard due to calcification or ossification of cartilage. Auricular ossification is a rare clinical entity. Transepidermal elimination is an intricate epidermal and dermal tissue response to foreign material. Here we report a case of a 62-year-old Greenland man, who developed unilateral ectopic ossification of upper pole helix cartilage of the auricle in combination with trans epidermal elimination of a small bone sequester, causing inflammation and painful ulceration.
