A Case of Bullous Transient Acantholytic Dermatosis

We report a case of a bullous variant of transient acantholytic dermatosis in a 59-year-old female. Each bullous lesion lasted several weeks and healed without scarring. The lesions were migratory and recurrent without a cleared period. Histopathologic examination revealed an intraepidermal vesicle low in the epidermis. The lesions cleared after 2 months of isotretinoin therapy.
