Adenoid cystic carcinoma of the skin

Introduction to adenoid cystic carcinoma of the skin Adenoid cystic carcinoma (the adenoid cystic carcinoma of theskin) occurs mainly in the salivary glands, followed by the lacrimal glands, the parotid glands and the mucous glands of the upper respiratory tract. A small number of patients also occur in the skin, mainly the head and chest. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious complication:

Causes of adenoid cystic carcinoma of the skin

(1) Causes of the disease

The cause is still unknown.

(two) pathogenesis

The pathogenesis is still unclear.

Skin adenoid cystic carcinoma prevention

Appropriate exercise, enhance physical fitness and improve your disease resistance. It is mainly aimed at preventing various factors that may lead to adenoid cystic carcinoma of the skin. It is currently believed that the loss of normal immune surveillance function, the tumorigenic effect of immunosuppressants, the activity of latent viruses and the long-term application of certain physical (such as radiation), chemical (such as anti-epileptic drugs, adrenocortical hormone) substances, It leads to the proliferation of lymphatic network. Therefore, pay attention to personal and environmental hygiene, avoid drug abuse, and pay attention to personal protection when working in a harmful environment.

Adenoid cystic carcinoma of the skin Complication

First, the lung metastasis of malignant tumors originating in other parts of the body is quite common in the lungs or lymphatics. According to statistics, 20 to 30% of cases of death from malignant tumors have lung metastases. The time of lung metastasis of malignant tumors varies from day to night. Most cases are metastasized within 3 years after the onset of primary cancer. It is also more than 10 years old, but there are also a few cases where lung metastases are found earlier than the primary tumor. .

Second, blindness causes vision loss, disappearance, etc.

Adenoid cystic carcinoma of the skin Common symptoms Pulmonary metastasis

It mainly occurs in the salivary glands, followed by the lacrimal glands, the mucous glands of the parotid gland and the upper respiratory tract, and a small number of patients occur in the skin, mainly the head and chest. The tumor grows slowly and is locally invasive, along the sarcolemma and nerves. Invasion of the bone, so it is difficult to completely remove, and even can cause lung metastasis.

Examination of adenoid cystic carcinoma of the skin

Histopathology: a single-shaped basal-like cell arranged in a tubular shape, long nested or cord-like, in a single-shaped basal-like cell nest, interspersed with a circular column of pale basophilic mucus matrix, another characteristic is the cell There is eosinophilic linear and small spherical basement membrane material deposition, the nucleus is tight, there are scattered chromosomes, the nucleoli are not obvious, the division is less, and the cell cytoplasm is less.

Diagnosis and differentiation of adenoid cystic carcinoma of the skin

According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
