AbstractPilomatrixomas, also known as epithelioma calcificans, are benign tumors of hair follicle matrix cells that are often mistaken for other lesions, especially cutaneous abscesses. We report an illustrative case in which a teenage girl developed a red, swollen earlobe that required multiple care visits and interventions until definitive diagnosis and treatment were provided. Although the lesion was initially treated as an abscess, it continued to progress in size and discomfort. The correct diagnosis was established after imaging and complete excision with pathologic examination. Ultimately, our patient was subjected to avoidable procedures that carried the risk of potentially negative cosmetic sequelae before the proper intervention. Although abscesses are common, it is important for clinicians to avoid incision and drainage of lesions, unless the diagnosis is certain.Copyright © 2019 Wolters Kluwer Health, Inc.
