Pemphigus vulgaris constituted the single largest group of 43 cases, followed by pemphigus foliaceus (25 cases) and pemphigus vegetans (2 cases). Majority of the cases were seen in the age group of 21-60 years, with a slight male predominance. The youngest patient was 14 years while the eldest was aged 75 years. Mucosal involvement was seen in 31 cases of pemphigus vulgaris, as opposed to only 5 cases of pemphigus foliaceus. Flaccid bullae were present in 100% cases. Pruritus was complained of in 14 cases, though it was more common in pemphigus vegetans and vulgaris.
