la equimosis

Equimosis is a Spanish medical term that refers to a type of bruise or discoloration of the skin usually caused by bleeding underneath due to trauma.

Meaning:

• Equimosis is a localized collection of blood outside the blood vessels (extravasation) in the skin or mucous membranes that causes a purple, blue, or black mark, often called a bruise.
• It results from the rupture of small blood vessels (capillaries) beneath the skin due to injury, causing blood to leak and pool.

Parts:

• Prefix "equi-" relates to "upon" or "outward."
• The full word comes from the Greek "ecchymosis," with "ek" meaning "out" and "chymos" meaning "juice," denoting blood leaking out.

Synonyms:

• Moretón (common term for bruise in Spanish)
• Contusión (contusion, bruise)
• Hemorragia subcutánea (subcutaneous hemorrhage)

Related Terms:

• Hematoma: A larger collection of blood outside vessels but often more raised/swollen.
• Petechia: Smaller pinpoint hemorrhages.

Antonyms:

As equimosis is a specific medical condition, it doesn't have a direct antonym, but possible conceptual opposites could be:

• Healthy skin without discoloration or bleeding
• Absence of trauma

Summary:

Equimosis is a medical term for bruising or blood pooling under the skin due to broken blood vessels, showing a patch of discolored skin generally due to trauma. It’s synonymous with bruise and contusion in everyday language.
