Tropical acne

Occupational and environmental acne is a variety of acne venenata, resulting from various chemical exposures and from a variety of environmental, physical and mechanical factors, usually encountered in the workplace but occasionally seen in non-occupational settings. The eruption may be mild, involving localized exposure or covered areas of the body, or severe, explosive and disseminated with the involvement of almost every follicular orifice. Additionally, chloracne almost always represents a cutaneous sign of systemic exposure to highly toxic chemicals. Occupational and environmental acne is separated into oil acne, coal-tar acne, acne cosmetica, acne aestivalis, acne mechanica, tropical acne and chloracne. This listing is not exhaustive but serves as a useful paradigm and includes the most common causes. 

Tropical acne may result from exposure to excessively hot or humid environments and, when such exposure is required in the performance of the patient s job, may be considered to be a form of occupational acne. Tropical acne has been observed most commonly in soldiers stationed in tropical climates, but variants may result from chronic exposure to other hot and/or humid environments as can be found in foundries (Mathias 1994).
