Infected Punctum–Associated Cyst Mimicking Erysipelas

Abstract

Epidermoid cysts (congenital and acquired) are not the unusual benign lesions. But to our knowledge, this is the first report in the English literature that describes an uncommon presentation of the infected acquired epidermoid cyst (ie, punctum–associated cyst or atheroma) manifesting as unilateral facial erysipelas in a 74-yearold Caucasian female. Terminology and the “submarine sign” ultrasound appearance are also analyzed.
