The Ale-Calo syndrome in monozygotic twins associated with bilateral cryptorchidism--case report

Abstract

A case report of identical male twins with the clinical and radiological features of the rare Ale - Calo or M.E.M.R. (Multiple Exostoses - Mental Retardation) or Langer-Giedion's syndrome - is presented. The additional finding of bilateral cryptorchidism in our case is also very rare in twins, and has hitherto not been described in association with the Ale - Calo syndrome. Differential diagnosis is reviewed briefly.
