Angiokeratomas

The most recognizable clinical feature of Fabry disease is angiokeratomas. These dark red or purple skin lesions (ranging in size from a pinpoint to several millimeters in diameter) do not blanch with pressure, and are usually distributed on the buttocks, groin, umbilicus, and upper thighs (bathing trunk distribution). Lesions generally appear in adolescence or young adulthood, and may become larger and more numerous with age. Angiokeratomas are almost universal in male hemizygotes; they occur in approximately 30% of heterozygous females.1-2
