Malignant eccrine helical adenoma
Introduction
Brief introduction of malignant small sweat gland spiral adenoma Malignantccrinespiradenoma is a rare disease, often caused by long-term malignant transformation of small sweat gland adenoma, local lymph node metastasis and fatal. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious complication:
Cause
The cause of malignant apocrine gland adenoma
The disease is rare, often caused by long-term malignant transformation of small sweat gland adenoma, high degree of malignancy, recurrence rate of about 30%, metastasis rate of 30% to 40%, mortality of 20%, local lymph node and lung metastasis, also Transfer to other internal organs.
Prevention
Malignant small sweat gland spiral adenoma prevention
There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.
Complication
Complications of malignant small sweat gland spiral adenoma Complication
First, distant metastasis: the most common metastatic sites of adenocarcinoma are brain, bone, liver and adrenal gland.
Second, cough: forty years old, no cause, intractable irritating cough, often an early warning of adenocarcinoma, especially the central type is more important.
Third, hemoptysis: an early signal of central lung cancer, because the blood vessels of the tracheal mucosa are abundant, but the bloodshot is very small.
Symptom

Clinical symptoms, skin lesions are not obvious.
According to clinical manifestations, skin lesions are not obvious, and can be diagnosed by histopathological features.
Examine
Examination of malignant small sweat gland adenoma
Histopathology: Two special structures, the typical benign small sweat gland adenomas and carcinomas, and the transition zone of the two can be seen. The cancer can be undifferentiated or have gland formation in some areas.
Diagnosis
Diagnosis and diagnosis of malignant small sweat gland adenoma
The appearance of adenocarcinoma in the morning and evening depends mainly on the location of the tumor. Adenocarcinoma often has intractable, irritating cough, bloody spots or a small amount of bloodshot, chest tingling or chest tightness and other symptoms. If the tumor is large, oppression may occur. Symptoms, ipsilateral diaphragmatic paralysis (oppression of the phrenic nerve), pleural qi dysfunction (invasion of the pleura), edema of the head, venous engorgement (compression of the superior vena cava), limb numbness, no sweat on the face, edema, drooping of the eyelids (branch plexus compression) ).
