solitary pilschwanoma
Introduction
Introduction to single hair follicle Solitary trich's tumor (solitarytrichilemmoma) was first reported by Headington and Prench in 1962. It is a single small papule that occurs in the face, especially the nose and cheeks. It has a diameter of 3 to 8 mm and has no characteristic clinical morphology. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific people Mode of infection: non-infectious Complications: sepsis
Cause
The cause of solitary hairstem
External root sheath tumor: a more common sickle tumor. May be related to the role of human papillomavirus. Multiple external root sheath stenosis, a hereditary skin disease, suggests that some benign and malignant tumors may occur in the viscera.
As well as the theory of Chinese medicine, it is believed that it is caused by wind, heat and poisonous evil on the skin: or angering liver fire, liver and blood dryness, gluten is not honorable, and the skin is not moist.
Prevention
Single hair sheath tumor prevention
Always keep the skin and mucous membrane clean and intact, avoid trauma, avoid squeezing or picking up sores with needles, actively treat and control chronic diseases, rational use of immunosuppressants and antibiotics, burn wards should be strictly disinfected, etc. Prevention occurs. If there is a single small papule in the nose and cheeks, you should see a dermatologist in time.
Complication
Single chorionic choroidal complications Complications sepsis
Single hair follicle tumor may be complicated by bacterial infection. Some symptoms may appear redness and swelling after bacterial infection. Most patients have no symptoms, but a few patients may have mild itching. If there is secondary infection, there may be Pain and other symptoms.
Clinically, some patients may also have irritability, cold limbs and purpura, rapid pulse rate, rapid breathing, and decreased blood pressure. Especially in the elderly, children, those with chronic diseases or immunocompromised, those who are not treated promptly and have complications, can develop sepsis or sepsis.
Symptom
Symptoms of single-shot chorionoma Common symptoms Pap
Single facial papules on the face, especially the nose and cheeks, 3 to 8 mm in diameter, no characteristic clinical morphology, most of the damage can be misdiagnosed as basal cell carcinoma or sputum, histopathology is one or several leaflets from The surface epidermis extends into the dermis, and some of the leaflets are in the same direction as the hair follicles containing hair in the center, and are surgically removed or electrocauterized.
Examine
Examination of single hairsynthesis
Histopathology: One or several leaflets protrude from the surface epidermis into the dermis. Some of the leaflets are in the same direction as the hair follicles containing hair in the center. The number of tumor cells in different sizes is transparent due to glycogen, and the common columnar columnar cells around the tumor leaflets And a distinctly thickened basement membrane band similar to the glass-like layer surrounding the lower part of the normal hair follicle.
Diagnosis
Diagnosis and diagnosis of single hairslipoma
diagnosis
According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.
Differential diagnosis
It should be differentiated from multiple external root sheath tumors, also known as Cowden's disease. This disease is autosomal dominant, mostly occurs in adults aged 20 to 40 years, with multiple facial nodules, oral mucosal fibroma and distal limbs. Dot-like keratinization triad.
Diagnosis by clinical manifestations and histopathological examination, facial lesions should be noted in pathological differentiation with inverted follicular keratosis, facial lesions and common sputum identification.
