Echinocytes in families with Duchenne muscular dystrophy.

abstract：:Two cases are reported of patients with deletions of chromosome 5q. Both have familial adenomatous polyposis (FAP) and mild mental retardation. In both, macroscopic polyposis was confined to the proximal colon in adult life (in their thirties) although microscopic adenomatosis was shown in the more distal colon with o...
