How is morphology of pemphigus?

➢ Pemphigus vulgaris involves both mucosa and skin ➢ Especially : scalp, face, axillae, groin, trunk, and points of pressure. ➢ The lesions are superficial flaccid vesicles and bullae that rupture easily, leaving deep and often extensive erosions covered with a serum crust . ➢ Pemphigus foliaceus, a rare, milder form of pemphigus, results in bullae that are mainly confined to the skin, with only infrequent involvement of mucous membranes. ➢ The blisters in this disorder are superficial, such that more limited zones of erythema and crusting of ruptured blisters are seen.
