Bullous diseases: a 7-year survey of experience with 77 patients.

A prospective study of 77 consecutive patients with bullous diseases was done to study the pattern and natural history. Pemphigus was the commonest with 45 patients (59%) followed by pemphigoid with 21 patients (27%). Pemphigoid was more common in Indians than in other ethnic groups and its age of onset was a decade later than pemphigus. Unusual immunofluorescent findings in both diseases are discussed. Six of the 7 patients with dermatitis herpetiformis had linear IgA in the dermo-epidermal junction and the classical papillary IgA deposits were absent. Ultrastructural findings of pemphigoid and dermatitis herpetiformis confirmed earlier reports. Chronic bullous dermatoses of childhood was seen in 4 patients, all of whom had total remission within one year of onset disease.
