Acne vulgaris is one of the many cutaneous diseases which has commonly been noted to flare up in Naval and Marine Corps personnel on duty in the tropics. This has been true aboard ship and at well established bases as well as under field conditions. The constant heat and increased humidity resulting in flushing and congestion of the skin and increased perspiration apparently favor its development. Changes in diet, neglect or inability to keep skin and clothing clean, emotional disturbances and many other factors are also doubtless important in individual cases.
Most important of all, however, in the causation of acne vulgaris is the inherent character of an individual's skin, especially as concerns the pilosebaceous apparatus. This is illustrated by the present case.
