papillary syringocystoma
Introduction
Introduction of nipple sweat cyst adenoma The differentiation of this tumor is still controversial. It is currently dominated by the differentiation of apocrine glands, and some are differentiated from small sweat glands. basic knowledge Sickness ratio: 0.1% Susceptible people: no special people Mode of infection: non-infectious Complications: sebaceous glands
Cause
The cause of nipple sweat cyst adenoma
(1) Causes of the disease
The cause is still unknown.
(two) pathogenesis
The pathogenesis is still unclear.
Prevention
Raw nipple sweat cyst adenoma prevention
Usually pay attention to participate in physical exercise, change your own low mood, maintain strong energy, thereby improving the body's immune function and disease resistance; pay attention to diet, drinking water hygiene, prevent cancer from entering the mouth; do not eat moldy, corrupt, burnt food And smoked, grilled, marinated, soaked food, or not drinking for a long time to store water, no smoking, no alcohol, scientific diet, eat more fresh vegetables, fruits and nutritious foods, develop good health habit. At the same time, attention should be paid to protecting the environment, avoiding and reducing pollution to the atmosphere, diet and drinking water, preventing physical, chemical and parasitic, viral and other carcinogenic factors from invading the human body and effectively preventing cancer.
Complication
Complications of nipple sweat cyst adenoma Complications sebaceous glands
Often associated with sebaceous glands.
Symptom
Symptoms of nipple sweat cyst adenoma common symptoms scarred nodules
Common in the head and neck, especially in the head, especially at birth or in early childhood, the lesions are single plaques and nodules, the development period is enlarged, and it becomes papilloma-like, about 2 to 3 cm in size. The surface is often moist, exudate and crusting, often associated with sebaceous glands.
Examine
Examination of nipple sweat cyst adenoma
Histopathology: The epidermis has different degrees of papillary-like proliferation, which expands downward from the epidermis into one or several cystic depressions. The upper part of the depression and some cases of cystic depression are mostly lined with keratinocytes similar to the surface epidermis. The lower part of the depression has a number of papillary protrusions extending into the cavity, and the lower part of the papillae and depression is lined with a glandular epithelium often composed of two rows of cells, which have an oval nucleus and It is composed of high columnar cells of light eosinophilic cytoplasm. Some cells are active and decapitated, and cell debris is seen in the cyst. The outer cells are composed of small cuboid cells with a round nucleus and a small amount of cytoplasm. Among the interstitial, especially the nipple protrusion, there are often a large number of dense cells infiltrated by plasma cells, which is highly diagnostic, and immunohistochemical staining for carcinoembryonic antigen is positive.
Diagnosis
Diagnosis and differentiation of nipple sweat cyst adenoma
According to the clinical manifestations, the characteristics of skin lesions, histopathology, immunohistochemical staining, and carcinoembryonic antigen-positive characteristics can be diagnosed.
