Regression of subcorneal pustular dermatosis type of IgA pemphigus lesions with azithromycin.

We present our experience with a 56-year-old man who complained for generalized dermatopathy, manifested by skin lesions with diameter from 0.5 to 5 cm. The lesions did not respond to a 20-day systemic steroid regimen. The results of biopsies of three excised lesions, in combination with the clinical manifestations, led to the diagnosis of subcorneal pustular dermatosis type of IgA pemphigus. An unexpected improvement was noted after treatment with azithromycin (which was provided for management of concurrent non-specific urethritis) and local non-potent steroid plus keratolytic agent ointment.
