piloblastoma
Introduction
Introduction to hairy cell tumor Trichoblastoma is a benign tumor of hair follicle blast cells and is rare in clinic. A single 1~2cm nodule appears in the dermis of the head and facial skin, and is surgically removed. A single 1 to 2 cm nodule appears in the dermis of the head and facial skin. Can be peeled off when removed, no symptoms. Found in adults, the incidence of men and women is equal. basic knowledge The proportion of illness: 0.0003% Susceptible people: no special people Mode of infection: non-infectious Complications: skin cancer
Cause
Cause of hairy cell tumor
(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. The pathological features are basal-like cell proliferation, and the tumor cells are cord-like, flaky or evacuated into clusters. The most common type of cable is 2 to 3 layers of cells, which are in agreement with each other and are isolated by the intercellular substance. The glassy membrane surrounds the cell cord.
Prevention
Hairy cell tumor prevention
The etiology of hairy cell tumor is still unclear. Understanding the risk factors of tumors and formulating corresponding prevention and treatment strategies can reduce the risk of tumors. There are two basic clues to prevent tumors. Even if tumors have begun to form in the body, they can help the body to improve resistance. The current focus of cancer prevention and treatment work should focus on and improve those factors that are closely related to our lives, such as Quit smoking, eat properly, exercise regularly, and lose weight. Anyone who follows these simple and reasonable lifestyles can reduce their chances of developing cancer.
Complication
Embryonic blastoma complications Complications skin cancer
Generally complicated by skin cancer.
Symptom
Hairy cell tumor symptoms Common symptoms Nodular subcutaneous nodules
A single 1~2cm nodule appears in the dermis of the head and facial skin. It can be peeled off when resected, without symptoms. It is found in adults, and the incidence is equal in men and women.
Examine
Examination of hairy cell tumor
Histopathology: basal-like cell hyperplasia, tumor cells are cord-like, flaky or scattered into clusters, the most common cord-like, 2 to 3 layers of cells, mutually coincident, and isolated by the interstitial cells, visible glass The membrane wraps around the cell cord, and the hair differentiates distinctly, or the immature cell clusters sprout from the cell cluster, and the interstitial bulge forms the original hairy nipple or hair bulb-like, which becomes a more mature hyperplasia, similar to the hairy root structure.
Diagnosis
Diagnosis and identification of hairy cell tumor
diagnosis
According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
Identification
1. Non-melanoma skin cancer (NMSC)
It is the most common malignant tumor in humans, and basal cell carcinoma is the most common. The number of male patients with basal cell carcinoma is slightly more than that of females. The older the patients, the higher the incidence. The incidence of Caucasian Caucasians is significantly higher than that of yellow racers.
Second, hair epithelioma
Hair Epithelial Tumor This tumor line originates from a benign tumor of the hair. It is generally believed that this disease may originate from pluripotent basal cells and is a benign tumor that differentiates into hair structure. The degree of differentiation is higher than that of basal cell epithelial tumors.
