Clinical Characteristics of Pseudolymphoma after Ear Piercing: A Report of Four Cases and Literature Review / 대한피부과학회지

ABSTRACT

Cutaneous pseudolymphoma, also referred to as cutaneous lymphoid hyperplasia or lymphocytoma cutis, is an uncommon lymphoproliferative condition. Most lesions are idiopathic in origin; however, triggers such as tattoos, acupuncture, or venipuncture are known to be associated with pseudolymphomas. Owing to the widespread popularity of cosmetic piercings, post-piercing pseudolymphomas are being reported in recent times. Anatomically, most lesions appear on the ears and present with a variety of morphological features, although diagnosis is based on distinctive clinical findings. In this case series, we report four cases of post-piercing pseudolymphoma on the earlobe together with a literature review. We emphasize close and careful monitoring to differentiate this rare condition from other lesions of the earlobe. In view of the diverse clinical presentations and treatment approaches available for pseudolymphomas, we highlight some preliminary clinical indicators to enable early diagnosis and prompt treatment of this condition.
