#structural anomaly
- Agastria — A rare pathological term or archaic medical word designating the complete, congenital, or surgical absence of the stomach (agastria); by extension, a functional or structural state in which gastric secretion and stomach-level digestion are completely halted. Clinically, the term reflects a severe anatomical anomaly requiring major therapeutic and nutritional restructurings of the digestive tract.
- Alagille-related — The feminine singular form of the neological adjective 'alagic'; relating to, originating from, or structurally associated with Alagille syndrome, a rare systemic genetic disorder characterized by the hypoplasia of interlobular bile ducts, cardiovascular malformations, skeletal anomalies (butterfly vertebrae), and distinct facial features. In clinical terminology, it describes a pathological manifestation, an organic impairment, or a specific cellular anomaly diagnosed within this hereditary syndromic complex governed by mutations in the JAG1 or NOTCH2 genes.
- Alloplasia — An abnormal, atypical, or structurally deviated development of a tissue or organ, characterized by an erroneous arrangement or cellular configuration that differs from the regular anatomophysiological norms of the species. This histological pathological phenomenon describes a state where cells, though mature, are organized in an aberrant architecture, altering the mechanical or functional properties of the affected anatomical region.
- Allotopy — An abnormal, atypical, or aberrant displacement, localization, or positioning of an element in a zone other than its natural one. In medicine (pathology/anatomy), it represents the congenital or acquired presence of an organ or tissue in an unusual place (ectopia, structural heterotopia); in linguistics and poetics, it defines a deviation from a text's normal semantic network (isotopy) by introducing a term foreign to the context to distort meaning or create a shocking metaphor.
- Amphicotyl — An anatomical formation or plant embryonic axis presenting a hybrid structure or a complete fusion of cotyledons, forming a tubular body around the central plumule; as an adjective, it describes a seed, embryo, or seedling affected by this type of structural layout, characterized by the coalescence of primary embryonic organs.
- Amphicotylism — A morphogenetic phenomenon or plant embryonic anomaly characterized by the total or partial structural fusion of the two cotyledons, resulting in a tubular or funnel-shaped structure that surrounds the central plumule. This anatomical modification, accidentally encountered in some dicotyledonous plants, is studied within plant teratology and seed ontogeny.
- Anachronism — A structural chronological error consisting of attributing an event, object, idea, or custom to a different historical era than the one in which it actually existed. In a broader socio-cultural sense, it designates an outdated mentality, institution, tradition, or norm of behavior that lags behind the general development level of current society, representing an obsolete and misplaced presence in the modern context.
- Andromastia — An extremely rare anatomical or medical condition characterized by the abnormal development or hypertrophy of mammary glands in male individuals, sometimes used as a historical or correlated terminological variant for gynecomastia, or to describe a mammary structure with sharp masculine somatic traits.
- Anophthalmic — Having no eyes; completely lacking the eyeball or visual organs. In zoology, it describes cave-dwelling, abyssal, or underground animal species (such as certain insects, fish, or crustaceans) that, following evolutionary adaptation to total darkness, have structurally lost their eyes. In medicine, it refers to an individual affected by anophthalmia, a rare congenital developmental anomaly of the orbit.
- Abnormality — The state, quality, or structural property of being abnormal; a clear deviation from the norm, from established rules, or from a physiological, anatomical, or psychological state considered healthy and typical. In a clinical context, the term designates the presence of a genetic anomaly, congenital malformation, or behavioral disorder that requires further investigation or treatment.
