The condition is nearly always either a symptom of some organic or systemic disease, or else due to the action of certain external irritants.

Symptomatic chloasma occurs with many conditions, among which may be mentioned Addison’s disease; exophthalmic goiter; chronic pulmonary tuberculosis; abdominal growths, tuberculous, cancerous or lymphomatous; hemochromatosis; arterio-sclerosis; heart disease, and chlorosis; and it may follow the prolonged ingestion of arsenic. But the most common form is that associated with pregnancy and utero-ovarian disorders (chloasma uterinum); this occurs usually between the ages of twenty-five and fifty years, and is rarely seen after the climacteric.
