Case Reports
Prolonged pustular eruption from hydroxychloroquine: an unusual case of acute generalized exanthematous pustulosis.
Acute generalized exanthematous pustulosis (AGEP) is a rare cutaneous eruption that often is a reaction to medications, most commonly antibiotics. Clinically, AGEP closely mimics pustular psoriasis and also is similar to subcorneal pustular dermatosis and IgA pemphigus. For clinicians, it is important to differentiate AGEP from pustular psoriasis. ⋯ We report a case of AGEP after HCQ administration that did not follow the usual course of resolution after medication cessation. The patient continued to experience cutaneous eruptions that waxed and waned for 81 days. Hydroxychloroquine has a particularly long half-life and is a known cause of AGEP; therefore, it is possible that HCQ-induced AGEP may not follow the typical rapid recovery time.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are considered to be among the most severe dermatologic emergencies with high risk for morbidity and mortality if managed poorly. These disease processes usually are the result of a reaction to antipsychotic or antibiotic medications, though the complete list of potential causative drugs is extensive. ⋯ Over the last several years, reports advocating the benefits of cyclosporine, corticosteroids, and intravenous immunoglobulin (IVIG) have shown variable responses in their treatment of SJS/TEN. In this article, cyclosporine and its potential as an emerging therapeutic option for SJS/TEN patients is discussed.
