Angiokeratoma corporis diffusum in GM1 gangliosidosis, type 1.
A patient with severe deficiency of beta-galactosidase, who developed skin lesions of angiokeratoma corporis diffusum between the 3rd and 10th month of life, is described. The activity of other lysosomal enzymes, including alpha-neuraminidase, was normal. The first signs of the disease were noticed during the first month of life. By 3 months coarseness of the face and psychomotor retardation were present. In addition to angiokeratoma, he had large mongolian spots and several scattered slate-blue spots of pigmentation over his body. With the exception of the skin lesions, the other clinical signs and the course of the psychomotor deterioration were within the clinical picture of GM1 gangliosidosis, Type 1. Angiokeratoma, a manifestation of several lysosomal disorders, may appear in GM1 gangliosidosis during the first year of life.
