skin purple streaks
Introduction
Introduction Purple skin of the skin refers to the skin with purple-red, silky, and different skin textures, often distributed in the lateral side of the hip, the inner and outer thighs, the underarms, the armpits and the lower abdomen, mostly associated with hypercortisolemia. Characteristic change. Clinically, it is caused by excessive secretion of glucocorticoids in the adrenal cortex caused by various causes. Clinically, the purple skin is one of the typical manifestations of Cushing's syndrome. Common diseases include secondary hypertension, adrenal hyperfunction, paralytic dementia, and so on.
Cause
Cause
Clinically, various causes of the adrenal cortex secrete excessive glucocorticoids. Clinically, the purple skin is one of the typical manifestations of Cushing's syndrome. Common diseases include secondary hypertension, adrenal hyperfunction, paralytic dementia, and so on.
Long-term use of glucocorticoids in the treatment of certain diseases can lead to clinical manifestations of cortisol, as well as adrenal cortical tumors, pituitary tumors, excessive secretion of corticotropin releasing factor (CRF) in the hypothalamus, and so on.

The skin has a purple-red streak due to obesity, thin skin, hyperproteolysis, and skin elastic fiber breakage. Distributed in the lateral side of the hip, the inner and outer thighs, underarms, armpits and lower abdomen, clinical and central obesity, more bloody face, buffalo back, hairy, hemorrhoids and other symptoms.
1, X-ray chest X-ray: Excluding lung cancer and lung metastases.
2, intravenous pyelography: understand the situation of both kidneys. Larger adrenal tumors can move the affected kidney down.
3, retroperitoneal angiography: Because adrenal adenoma is generally not too large, and obese patients with large block of adipose tissue can often lead to misdiagnosis, is now rarely used.
4, B-ultrasound: convenient and effective. The correct rate of localization diagnosis of adrenal cortical tumors can reach more than 90%.
5, CT: most of the adrenal adenomas with a diameter of 0.5 ~ 1cm or more can be correctly positioned.
Diagnosis
Differential diagnosis
Clinically often identified with pigmentation.
Pigmentation: It is the change of pigmentation of human skin with different colors, different ranges and different shades due to various reasons. In terms of human skin, there are two types of pigments: one is a pigment produced by the body itself, such as melanin produced by melanocytes present in the skin. Due to the different shades of melanin, different shades are displayed: black or brown in the epidermis, grayish blue in the shallow layer of the dermis, and cyan in the deep layer of the dermis. Endogenous pigments include lipoproteins and biliary pigments. The other type is exogenous foreign pigments, such as carotene), drugs (such as arsenic can cause skin yellowing, etc.) and heavy metals (such as arsenic, strontium, silver, etc.) and foreign bodies Coloring, such as tattoos, silt, iron slag, cinder, etc. in the skin's stagnation.
