This is a close-up picture of chickenpox. Early chickenpox lesions consist of small red papules which quickly fill with a yellowish or straw colored fluid to form small blisters (vesicles), as seen in this photograph. Later, these vesicles will rupture forming shallow erosions that crust over and then ultimately heal.
