[Polydactyly in a foal--a case report].

Polydactylism, an excess deformity in a foal is described. The hereditary pathology and etiopathogenesis are discussed. A method of surgical correction of the deformed extremity is introduced. Indication and prognosis of the surgical correction of polydactylism and aspects concerning the breeding management are discussed.

Hallux duplication, postaxial polydactyly, absence of the corpus callosum, severe mental retardation, and additional anomalies in two unrelated patients: a new syndrome.

Two unrelated patients, a 4-year-old boy and a 2 1/2-year-old girl, presented with a similar pattern of abnormalities. Both had severe mental retardation, macrocephaly, absence of the corpus callosum, unusual facial appearance, duplication of hallucal phalanges, postaxial hexadactyly of finger phalanges, and 2/3-syndactyly of toes. The boy also had postaxial hexadactyly of toe phalanges, inguinal hernias and umbilical hernia, and growth retardation. We suspect a common cause of this apparently "new" syndrome, most likely a gene mutation.

Congenital hypothalamic hamartoblastoma, hypopituitarism, imperforate anus, and postaxial polydactyly--a new syndrome? Part II: Neuropathological considerations.

Unusual and virtually identical hypothalamic tumors were recently studied in three unrelated neonates with a similar complex malformation syndrome. Previous reports of either the hypothalamic tumors or the syndrome as a whole have not been found. Each tumor was apparent on the inferior surface of the cerebrum and extended from the optic chiasma to the interpeduncular fossa. The tumor replaced the hypothalamus and other nuclei which originate in the embryonic hypothalamic plate; it was principally composed of cells resembling primitive, undifferentiated germinal cells. The term "hamartoblastoma" is used to designate these tumors in order to emphasize the malformational and neoplastic aspects. In addition, short olfactory tracts suggest a relation to the arrhinencephaly field defect.

Mirror polydactyly: pathogenesis based on a morphogen gradient theory.

We report on an infant with 7 toes of the left foot in a mirror configuration in association with ipsilateral duplication of the calcaneus and fibula, tibial aplasia, femoral hypoplasia, and a teratomatous sacrococcygeal tumour. The possible pathogenetic mechanisms leading to this limb abnormality are discussed with special emphasis on a field morphogen gradient hypothesis.
