Abstract

Cutaneous lymphoid hyperplasia (CLH, pseudolymphoma) refers to a heterogeneous group of benign reactive T- and/or B-cell lymphoproliferative diseases of the skin, that resemble cutaneous lymphoma both clinically and histologically. Despite the unknown causes of CLH development, various stimuli can induce CLH, such as medications, infections, insect bites, photosensitivity and foreign agents. To date, there has been no reported case of CLH development after an allergy skin test of antibiotics. Thus, we report a patient who developed CLH following an allergy skin test of antibiotics. He was a 21-year-old man who presented with 1.5x1.5 cm sized erythematous plaque with yellowish crusts on his right forearm that showed features of a CLH, based on histopathologic assessment.
