Eccrine sweat cyst

Brief introduction of small sweat gland cyst The small sweat gland cyst (eccrinehidrocystomas) may cause temporary or permanent stagnation of the ductal malformation of the small sweat gland, and the enzyme histochemistry shows the presence of small sweat gland enzymes, phosphorylase and succinate dehydrogenase. basic knowledge Sickness ratio: 0.05% Susceptible people: multiple women Mode of infection: non-infectious Complications: pruritus

Causes of small sweat gland cyst

(1) Causes of the disease

The etiology of this disease is not clear, and may have certain correlation with environmental factors, genetic factors, dietary factors, and mood and nutrition during pregnancy.

(two) pathogenesis

The pathogenesis is still unclear. Histopathological examination: This tumor is located in the dermis and appears as a single cystic cavity. There are often two layers of small cuboid epithelial cells on the wall of the capsule. However, in some areas, only a single layer of squamous epithelial cells is seen, the nucleus of which is parallel to the wall of the capsule. Occasionally, the papillary protrusions that protrude into the cyst were seen. The serial section showed that the small sweat duct was introduced from below the cyst, but it was not connected to the epidermis.

Prevention of small sweat gland cyst

The etiology of this disease is not clear, and may have certain correlation with environmental factors, genetic factors, dietary factors, and mood and nutrition during pregnancy. Therefore, it is impossible to directly prevent the disease against the cause. Early detection, early diagnosis, and early treatment are important for indirect prevention of this disease, and can also reduce the incidence of infection complications. For patients with existing infections, antibiotics should be used as soon as possible.

Complications of small sweat gland cysts Complications pruritus

The disease is mainly caused by blockage of sweat glands and symptoms of surrounding tissue compression. After the sweat gland is blocked, it will cause the secretion of sweat to be affected. If it is secreted in the summer, it can cause itching. Secondly, due to the formation of the sac, the perspiration disorder, the bacterial infection in the sac can be combined, and if necessary, cystic incision drainage treatment and systemic anti-infective treatment are needed.

Small sweat gland cyst symptoms common symptoms cyst pimples

The skin lesion is located on the face, which is a translucent papule of 1~3mm size. It is light blue, and usually has a single hair, but it also has multiple lesions. When it is hot, the skin lesions increase and become obvious, and the winter is reduced or reduced. It is more common in women. .

Diagnosis and differentiation of small sweat gland cyst

diagnosis

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

Differential diagnosis

The disease should be differentiated from sweat adenoma, a benign skin appendage tumor, which is closely related to sweaty tumor. Some scholars use acromiotomy to name sweat adenoma and sweaty tumor. It is currently believed that sweat adenomas are derived from both apocrine sweat glands and small sweat glands. The symptoms are similar, but the pathological examination can be completely distinguished. Secondly, cysts of the sweat glands are also required, which are identified by pathology and clinical features.
