Two cases of congenital dyserythropoietic anaemia type I associated with unusual skeletal abnormalities of the limbs.

This report describes the cases of two young female patients with congenital dyserythropoietic anaemia (CDA) type I who presented similar hand and foot skeletal abnormalities: lack of distal phalanges and nails, and syndactyly. Up to now, some morphological malformations have been described in association with CDA type I but there is no report of skeletal defects. These two cases are suggestive of a possible association between this hereditary anaemia and specific skeletal abnormalities of the distal extremities.
