Figure 2. Progressive upper limb edema following a viper bite.

Extended view of the affected upper limb showing diffuse edema involving the hand, wrist, and forearm, with proximal extension to the upper arm and shoulder. The bite site on the second digit shows discoloration and early necrotic changes, with marked soft-tissue swelling throughout the limb. These findings developed within approximately one hour after arrival at the emergency department, consistent with rapidly progressive local venom-related tissue injury.
