| L Leg | 18% | ||
| R Leg | 18% | ||
| Genitals | 1% |
Skin Involvement Score:0.0
Skin involvement total score: (% BSA × weighting factor = 0–150 points)

Clinical Notes:
- •ABSIS assesses the intensity of autoimmune bullous skin disorders
- •Total score ranges from 0-206 points
- •Skin involvement: 0-150 points (BSA × weighting factor)
- •Oral involvement: 0-11 points (presence/absence of lesions)
- •Severity: 0-45 points (discomfort level × factor)
- •Weighting factors reflect lesion appearance: erosive/exudative (1.5), erosive/dry (1.0), reepithelialized (0.5)
- •Higher scores indicate more severe disease
