Background:
A study of five cases of linear IgA dermatosis (LABD) in a referral hospital in South India is presented.
Methods:
A dermatologic examination, skin biopsy, and direct immunofluorescence were carried out on all patients. Patients were then followed up.
Results:
All five cases showed linear IgA deposits at the dermo-epidermal junction. One case in addition showed IgG and C3 deposits. All cases responded to treatment with dapsone. The treatment duration varied from 14 to 16 months and the fifth patient is still on treatment after 37 months.
Conclusions:
Linear IgA bullous dermatosis is a self-limiting bullous disorder. To the best of our knowledge this is the first report of LABD from India.
