Beta-lactam antibiotic-induced pseudoporphyria.
A case of beta-lactam antibiotic-induced pseudoporphyria is presented. A 24-year-old African American woman with systemic lupus erythematosus and end-stage renal disease on hemodialysis developed tense bullae on her forehead and cheeks after exposure to ampicillin-sulbactam and cefepime. Histologically, the lesions were similar to porphyria cutanea tarda, but without the associated porphyrin abnormalities. The lesions resolved spontaneously on cessation of the antibiotics.
