Abstract

OBJECTIVE: To examine clinical, etiologic, and histologic features of Stevens-Johnson syndrome and to identify possible correlates of clinical disease severity related to etiologic and histopathologic findings.

PATIENTS AND METHODS: This is a retrospective review of patients seen at Mayo Clinic between January 1, 2000, and December 31, 2007.

RESULTS: Of 27 patients (mean age, 28.1 years), 22 (81%) had involvement of 2 or more mucous membranes, and 19 (70%) had ocular involvement. Medications, most commonly antibiotics and anticonvulsants, were causative in 20 patients. Mycoplasma pneumoniae infection caused 6 of the 27 cases. Corticosteroids were the most common systemic therapy. No patients with mycoplasma-induced Stevens-Johnson syndrome had internal organ involvement or required treatment in the intensive care unit, in contrast to 4 patients each in the drug-induced group. Three patients had chronic ocular sequelae, and 1 died of complications. Biopsy specimens from 13 patients (48%) showed epidermal necrosis (8 patients), basal vacuolar change (10 patients), and subepidermal bullae (10 patients). Biopsy specimens from 11 patients displayed moderate or dense dermal infiltrate. Histologic features in drug-induced cases included individual necrotic keratinocytes, dense dermal infiltrate, red blood cell extravasation, pigment incontinence, parakeratosis, and substantial eosinophils or neutrophils.

CONCLUSION: Our clinical and etiologic findings corroborate those in previous reports. M pneumoniae—induced Stevens-Johnson syndrome manifested less severely than its drug-induced counterpart. The limited number of biopsies precludes unequivocal demonstration of histopathologic differences between drug-induced and M pneumoniae—induced Stevens-Johnson syndrome.
