amastia

Thân thiện

Definition

Noun: A rare congenital condition characterized by the complete absence of one or both mammary glands (breasts) and nipple-areola complexes from birth. It can also refer to the absence of breast tissue resulting from surgical intervention.

Usage

The term is used in medical contexts to describe a specific anatomical absence. - The patient was diagnosed with bilateral amastia, a condition present since birth. - Following the radical mastectomy, the patient experienced surgical amastia.

Advanced Usage

• Congenital Amastia: Often used to specify the condition when it is a developmental defect, sometimes associated with other syndromes like Poland Syndrome.
  • Congenital amastia is frequently noted in the medical literature as an isolated anomaly.
• Unilateral/Bilateral Amastia: Used to specify whether one or both breasts are absent.
  • Unilateral amastia can present significant psychological and reconstructive challenges.

Variants and Related Words

• Amazia (noun): A related but distinct condition involving the absence of mammary gland tissue while the nipple and areola are present.
• Mastectomy (noun): The surgical removal of a breast, which results in acquired amastia.

Synonyms

• Athelia (noun): Specifically refers to the absence of the nipple. Note: This is different from amastia, which involves the entire gland.
• Breast aplasia (noun): A synonymous medical term for the congenital absence of breast tissue.

Notes on Meaning

This term has a highly specific medical meaning. It does not refer to small breast size (micromastia) or the normal absence of developed breasts in children or males. Its usage is almost exclusively clinical.
