Alder's anomaly  an autosomal dominant condition in which leukocytes of the myelocytic series, and sometimes all leukocytes, contain coarse azurophilic granules.

Chédiak-Higashi anomaly  see under syndrome.

congenital anomaly  a developmental anomaly present at birth.

developmental anomaly 

1. a structural abnormality of any type.

2. a defect resulting from imperfect embryonic development.

Ebstein's anomaly  a malformation of the tricuspid valve, usually associated with an atrial septal defect.

Ebstein's anomaly, showing displacement of the septal and posterior leaflets of the tricuspid valve into the right ventricle and accompanied by a patent foramen ovale.

May-Hegglin anomaly  an autosomal dominant disorder of blood cell morphology, characterized by RNA-containing cytoplasmic inclusions (similar to Döhle bodies) in granulocytes, by large, poorly granulated platelets, and by thrombocytopenia.

Pelger's nuclear anomaly  Pelger-Huët nuclear a. (1).

Pelger-Huët nuclear anomaly 

1. a hereditary or acquired defect in which the nuclei of neutrophils and eosinophils appear rodlike, spherical, or dumbbell-shaped; the nuclear structure is coarse and lumpy.

2. an acquired condition with similar features, occurring in certain anemias and leukemias.

Etymology: Wilhelm Ebstein, German physician, 1836-1912; Gk, anomalia, irregularity

a congenital heart defect in which the tricuspid valve is displaced downward into the right ventricle. The abnormality is often associated with right-to-left atrial shunting and Wolff-Parkinson-White syndrome.
