Acrocyanosis

Introduction Hair bun is a manifestation of increased hemoglobin in the blood, which causes the skin and mucous membranes to change in blue-purple color. It can also be called purpura. Acromegaly, the onset of symptoms is cold limbs and cyanosis in the limbs. More common in young women. Such blemishes are often caused by peripheral circulation blood flow disorders. Its characteristics are manifested in the fact that cyanosis often occurs at the end and sagging of the limb. The skin in these areas is cold, but if you give a massage or warming, the skin will warm up and the bun will fade.

Cause

Skin changes occur in areas where the subcutaneous fat layer is thick and where it is exposed to the cold due to fashion. Endocrine dysfunction also plays a role.

Such blemishes are often caused by peripheral circulation blood flow disorders. Its characteristics are manifested in the fact that cyanosis often occurs at the end and sagging of the limb. The skin in these areas is cold, but if you give a massage or warming, the skin will warm up and the bun will fade. This feature can also be used as a point of identification for central cyanosis. This type of hair can be divided into:

1 bloody peripheral hair cyanosis: common in diseases causing systemic congestion, slow blood flow around, such as right heart failure, exudative pericarditis, pericardial tamponade, constrictive pericarditis, thrombophlebitis, superior vena cava obstruction Signs, varicose veins of the lower extremities, etc.

2 ischemic peripheral hair loss: common in diseases that cause a decrease in cardiac output and local blood flow disorders, such as severe shock, exposure to cold and thromboangiitis obliterans, Raynaud's disease, limb hair cyanosis Symptoms, cryoglobulinemia, etc.

Occasional in girls and young women wearing short skirts or obesity, frequent in cold regions and seasons. The lesions often involve both hands, showing the ends of the extremities. Continuous, uniform blemishes can occur throughout the hands and wrists and even the back, cold, and exposure to cold air can exacerbate symptoms, but warm environments often cannot reduce or disappear. With the swelling of the fingers, stiffness, and sweating of the palms. No ulcers or gangrene were formed.

It is not difficult to diagnose a typical extremity. Both hands and (or) both feet are cyanotic, local skin temperature is reduced and cool, but the patient does not feel pain, numbness, aggravation in cold environment, but it is relieved in warm environment but not completely disappeared. To identify primary or secondary. In principle, it should first be comprehensively examined, detailed medical history, comprehensive physical examination and various auxiliary examinations. If there is no possibility of secondary acromegaly, it may be considered as a primary extremity snoring.

Differential diagnosis

True hair blemishes must also be distinguished from pseudo-caries, which are caused by increased hemoglobin in the blood or abnormal hemoglobin. The latter is due to abnormal pigmentation of the skin membrane (such as silver stagnation, gold stagnation, Addison's disease, etc.) or foreign matter deposition caused by silver or gold deposition. Generally limited to the skin, not to the film. Although the pigmentation caused by Addison's disease can be seen in the whole body skin tax film, it is especially obvious at the place where the palm veins are easy to rub or the epilepsy. The discoloration caused by the foreign matter is still pressed back after the blood is squeezed out, which is different from the hairpin.

The lesions often involve both hands, showing the ends of the extremities. Continuous, uniform blemishes can occur throughout the hands and wrists and even the back, cold, and exposure to cold air can exacerbate symptoms, but warm environments often cannot reduce or disappear.
