Major bulk of skin manifestations were chronic including skin scars 66% (n=33), xerosis 60% (n=30), hyperpigmentation 58% (n=29), oral mucosal changes 94% (n=47) and facial skin changes 60% (n=30). Acute along with chronic skin changes were observed in 30% (n = 15) mainly including injection marks 30% (n = 15), vascular changes 12% (n=6) and infections 8% (n=4).
