PLATE NO. VII Burning of scrotum and penis by mustard gas.

History of case. From the same incident as that described under Plate No. VI. Inflammation commenced at the close of the first day after exposure. Drawing made on the eleventh day when the red erythema had almost faded from the inner aspects of the thighs. The scrotum is oedematous and the raw surfaces have become the seat of a mild secondary eczematisation. The injuries were soon and completely healed.

The perineum is peculiarly liable to be inflamed after exposure to the vapour of mustard gas, and the penis and scrotum become oedematous as well as reddened. Balanitis and pain with micturition may be troublesome. When the skin is excoriated, secondary infections of the raw surface are very likely to develop unless adequate precautions are taken to prevent sepsis. But with careful cleansing of the skin and clothes of a casualty after exposure to the vapour, inflammation of the perineum can be reduced to a comparatively trifling incidence.
