Black neck disease may be acanthosis nigricans, which is mainly characterized by skin pigmentation with velvety thickening.
The cause of acanthosis nigricans is not clear at this stage, but may be related to endocrine disorders, obesity, heredity and sun exposure. Depending on its clinical nature, it is divided into benign and malignant acanthosis nigricans, of which benign acanthosis nigricans generally does not affect the body, while malignant acanthosis nigricans is generally related to malignant tumors in the body.
For endocrine disorders, the symptoms of acanthosis nigricans can be improved through symptomatic treatment, such as hypoglycemic treatment for diabetes mellitus. For obesity-related acanthosis nigricans, the symptoms of acanthosis nigricans will gradually improve after weight control. For acanthosis nigricans caused by malignant tumors, surgical treatment is needed as soon as possible.
Due to the different causes of the disease, the treatment plan is different, and the specific situation requires a doctor’s consultation.
