Multifocal and recurrent cutaneous pseudolymphoma associated with lamotrigine and review of the literature

Cutaneous pseudolymphoma (CPL) is a benign lymphoproliferative condition that clinically mimics malignant cutaneous lymphoma. CPL often presents as a solitary violaceous–erythematous papule, nodule, or plaque. Rare multifocal or disseminated cases have been reported.1 While most cases of CPL are idiopathic, known triggers include photosensitivity, HIV, Varicella zoster virus, Borrelia burgdorferi, tattoos, minor trauma, insect bites, and medications.1 Some of the medication classes known to cause drug-induced CPL are anticonvulsants, tumor necrosis factor-alpha inhibitors, antibiotics, and antihypertensives.
