(dis'mă-chūr'i-tē),
Syndrome of an infant born with relative absence of subcutaneous fat, wrinkling of the skin, prominent finger and toe nails, and meconium staining of the infant's skin and of the placental membranes; often associated with postmaturity or placental insufficiency.

dysmaturity

[dis′machoo͡r′itē]
Etymology: Gk, dys + L, maturare, to make ripe
1 the failure of an organism to develop, ripen, or otherwise achieve maturity in structure or function.
2 the condition of a fetus or newborn who is abnormally small or large for its age of gestation. Kinds of dysmaturity are small for gestational age and large for gestational age. Compare postmature infant, premature. dysmature, adj.

dysmaturity

A nonspecific term used for various conditions.
(1) Disordered development—e.g., of a foetus; maldevelopment appears preferable.
(2) Postmaturity; postmaturity syndrome.
(3) The condition of being small or immature for gestational age, said of foetuses that are the product of a pregnancy involving placental dysfunction; immature and small for gestational age are both terms that are better understood.
(4) Failure of an organism to develop or achieve structural or functional maturity; immaturity appears preferable.
(5) Placental dysfunction.

Given the confusing overlap of varying definitions, it is best unused in the working medical parlance.

congenital hypothyroid dysmaturity syndrome
of foals occurs predominantly in the prairie provinces of Canada and the Pacific Northwest and is manifest by prolonged gestation, dysmaturity and limb deformity due to delayed ossification of the carpal bones. Histologically, but not grossly, there is thyroid hyperplasia. In Canada, the syndrome has been associated with high nitrate concentrations in feed, but in the western United States epidemiological data suggest it occurs in late-foaling mares and results from ingestion of goitrogenic winter annual mustard species in the latter three months of gestation.
