[Diffuse hyperkeratotic papules of the lower abdomen and genital region in a 38-year old male patient]. / Diffuse hyperkeratotische Papeln am unteren Abdomen und im Genitalbereich bei einem 38­jährigen Patienten.

A patient with diffuse angiokeratomas of the lower abdomen and genital region was diagnosed with Fabry disease on the basis of genetic testing. Fabry disease is an X-linked lysosomal storage disease that can affect several organ systems including the heart or kidneys, resulting in reduced median survival. Pathogenetically, Fabry disease leads to a deficiency of the lysosomal enzyme α­galactosidase A (α-GAL A). Treatment options include lifelong enzyme replacement therapy or chaperone therapy.
