The trichorhinophalangeal syndrome with repeated dislocation of the patella.

The trichorhinophalangeal syndrome associated with laxity of the skin and joints has been mistaken for Ehlers-Danlos syndrome (Jones 1988). We report a case of the trichorhinophalangeal syndrome which we mistook for the Larsen syndrome. Literature and published photographs of the Larsen syndrome are reviewed to highlight the similarities between these two entities. These observations may be of value in the genetic mapping of the Larsen syndrome, which perhaps is a contiguous gene syndrome.
