What is Acrocyanosis

Answers

Answer:

below is the meaning of it

Explanation:

Acrocyanosis is persistent blue or cyanotic discoloration, most commonly occurring in the hands, although it also occurs in the feet and distal parts of face.

Acrocyanosis is persistent blue or cyanotic discoloration, most commonly occurring in the hands, although it also occurs in the feet and distal parts of face.

What is Acrocynosis?

Due to decreased oxyhemoglobin, it is a functional peripheral vascular disease marked by bluish coloring of skin and mucous membranes. It could be caused by abnormalities in the central or local tissue oxygenation.

It is a painful episodic condition in which ulceration and trophic alterations are extremely uncommon outside of the necrotizing variety. It is defined as a persistent, excessively deep blue or cyanotic staining of the skin over the extremities (most frequently the hands and feet) caused by a reduction in oxyhemoglobin.

It can have mental, neurological, autoimmune, infectious, metabolic, or other primary or secondary causes. According to the current theory, blood rheology impairment is less likely than vasospastic response to play a major impact.

Therefore, Acrocyanosis is persistent blue or cyanotic discoloration, most commonly occurring in the hands, although it also occurs in the feet and distal parts of face.
