Age distribution of pemphigus vulgaris patients. Diagnosed patients of pemphigus vulgaris were grouped into four categories, according to their age: children and young (0–25 years), young adults (25–40 years), late adults (40–60 years) and elderly (>60 years) to establish the age at which the disease manifests.
