Gangliosidosis is a rare type of lipidosis, or lipid storage disorder, in which the lipids affected are the gangliosides. Lipid storage disorders are hereditary disorders in which harmful amounts of lipids, or fats, accumulate in body tissues and cells. Gangliosides are lipids located on the surface of cells.
A ganglion is also a collection of nerve cell bodies located outside the central nervous system. This article refers only to fluid-like swellings that form on top of joints, tendons in the wrists, hands and feet (ganglion cysts). Women are more likely than men to develop ganglion cysts. The risk of ganglion cysts is also greater for those who stress the wrist and hand with regular repetitive movement, who have osteoarthritis, and who have injured joints or tendons in the hands or feet. The exact causes of ganglion cysts remain unknown.
