Addisonian pigmentation is characterised by diffuse pigmentation of skin and mucosae with accentuation over the sun exposed, flexural and periungual areas. We report “Addisonian pigmentation” in a 4–year–old boy secondary to non–classical adrenal hyperplasia and possibly ectopic ACTH secretion. This case underscores the significance of hormonal evaluation in cases of diffuse hyperpigmentation in childhood.
