Calf red cyanosis

Brief introduction of calf red rickets Erythrosis (erythrocyanosis crurum), also known as erythrocyanosis crurum, is characterized by young women with a purple-red and mild swelling of the calf skin. This disease is more common in cold regions, so it is considered to be a vascular abnormal reaction caused by long-term cold. Often occurs in thicker parts of the subcutaneous fat layer. Some scholars believe that it is related to tuberculosis, endocrine dysfunction, and congenital vascular dysfunction. basic knowledge Sickness ratio: 0.002%-0.004% Susceptible people: young women are good Mode of infection: non-infectious Complications: frostbite, hard erythema

Causes of calf red rickets

Cause:

This disease is more common in cold regions, so it is considered to be a long-term cold caused by abnormal blood vessels, often occurs in the thick part of the subcutaneous fat layer, and some scholars believe that it is related to tuberculosis, endocrine dysfunction, congenital vascular dysfunction.

Calf red rickets prevention

More common in young women, it occurs in the lower third of the calf and the thigh, especially in the calf, the skin of the affected area is dark red or deep purple red edema, rare unilateral disease, local skin temperature is low Can also be expressed as follicular erythema, follicular keratinization or diffuse desquamation, a few nodules can be broken to form small ulcers, some cases can also have a history of night leg, can also be associated with frostbite, hard erythema-like nodules Damage, conscious symptoms are mild, occasionally itching and discomfort, the course of the disease is uncertain, there are several years of natural improvement, there are also slow development of skin hypertrophy and fibrosis, and the winter is intensified.

Examination of calf red rickets

Histopathology: There are only a few acute inflammatory cells or a few lymphocytes infiltrated in the dermis; severe vasodilatation in the dermis, swelling of vascular endothelial cells, edema in the dermis, and a small amount of red blood cell overflow, occasionally caused by thrombosis Infarction.

Diagnosis and identification of calf red rickets

According to the symmetrical purple-red color of the lower limb skin, the skin temperature is low, and the cold season is aggravated. Young women are ill and the diagnosis is not difficult.

The disease needs to be differentiated from the extremity cyanosis, the latter part of the disease is the hands and feet and the performance is continuous cyanosis, easy to identify. Acromegaly is usually seen in cold winters. As the temperature decreases, the capillary network of the skin mucosa shrinks, resulting in slow blood circulation, blood stasis, decreased oxygenation and decreased hemoglobin, which can lead to cyanosis.
