The chart of Lund and Browder for percent body surface area (BSA) in a given body region can be used to describe the extent of skin disorder.
Parameters:
(1) age in years
(2) body region
(3) severity of skin involvement (none, mild, moderate, severe)

extent of involvement by a degree of skin disease in a region =
= (percent of body surface area in a region) * (percent of region showing that level of severity) / 100
The sum of the areas for each region should add up to 100%.
Purpose: To estimate the extent of a patient's body surface area (BSA) involved by a skin disorder at various degrees of severity.
Specialty: Dermatology
Objective: severity, prognosis, stage
ICD-10: L00-L99, T29-T32,
