Subtypes of this disorder are dependent on the offending agent and include acne mechanica, chloracne (caused by, eg, Agent Orange, dioxins), oil acne, and coal tar acne.
Exposure to the offending agent results in follicular obstruction, with subsequent development of acneiform lesions. Comedones often predominate. Areas that are covered by clothing can also be affected, such as when oils or coal tar seep through clothing.
An individual's body mass index (BMI) and body fat mass are reported to be predisposing factors to acquiring the disorder.
