#structural pathology

• Amastia — A rare congenital anomaly characterized by the complete unilateral or bilateral absence of breast tissue, areola, and nipple. Clinically, this embryonic development malformation results from the failure of the mammary ridge to proliferate during early gestation.
• Amastia — An alternative spelling variant or adapted graphical form in medical literature for 'amastie' (amastia); a rare congenital anomaly characterized by the complete unilateral or bilateral absence of breast tissue, areola, and nipple.
• Amaurotic (feminine) — The feminine singular form of the adjective 'amaurotic'; pertaining to amaurosis or characterized by total or partial loss of vision without apparent external structural lesions of the eye. In clinical semiology, it qualifies ophthalmological manifestations such as the amaurotic pupil.
• Androgalactosemia — An extremely rare hereditary metabolic condition manifested exclusively in male patients, characterized by the organism's structural inability to correctly metabolize galactose due to a specific enzyme deficiency linked to the X chromosome or influenced by androgen hormones, leading to toxic compounds accumulation.
• Androgenetic — Determined or jointly influenced by the action of androgen hormones and hereditary (genetic) factors. In a dermatological and structural context, the term most frequently describes androgenetic alopecia (male or female pattern baldness), a condition characterized by the progressive hair follicle miniaturization under the influence of dihydrotestosterone in genetically predisposed individuals.
• Andrology — A branch of medicine dealing with the study of the anatomy, physiology, and pathology of the male reproductive and urogenital systems, alongside the investigation of hormonal imbalances and sexual dysfunctions specific to men. Structurally, this clinical specialty represents the equivalent of gynecology for women, being crucial in the diagnosis and treatment of male infertility.
• Anemia — The definite articulated form of the feminine noun 'anemie', designating a hematological condition characterized by a decrease in the number of erythrocytes (red blood cells) or the hemoglobin concentration below normal values. This pathological process disrupts structural oxygen transport.
• Inducement of anemia — The action of causing anemia or the process of becoming anemic; a pathophysiological process whereby the organism or a tissue undergoes a decrease in red blood cells or hemoglobin concentration. This phenomenon structurally alters oxygen transport to cells, leading to clinical weakness.
• Anemia — A pathological condition characterized by a decrease in the number of erythrocytes (red blood cells) or the concentration of hemoglobin in the blood below the normal age- and sex-adjusted values. This pathophysiological process disrupts the structural transport of oxygen to tissues, manifesting clinically as pallor, chronic fatigue, muscle weakness, and dizziness.
• Inducement of anemia — The action of causing anemia or the process of becoming anemic; a progressive pathophysiological process whereby the organism or a tissue undergoes a decrease in red blood cells or hemoglobin concentration. This phenomenon structurally alters oxygen transport to cells.
• Aptyalism — A perfect clinical synonym for aptyalia; a pathological condition marked by a severe deficit or total absence of saliva secretion in the oral cavity, leading to difficulties in swallowing, speech, and the rapid degradation of gingival health.
