lichen scrofula
Introduction
Introduction to spastic moss Lichenscrofulosorum is also known as tuberculosis cutislichenoides, or disseminated follicular skin tuberculosis or glandular moss. It is characterized by scattered lichen-like follicular papules that occur in the child's torso. basic knowledge The proportion of illness: 0.0058% Susceptible people: no special people Mode of infection: respiratory transmission Complications: tuberculosis
Cause
Cause of spastic moss
(1) Causes of the disease
Patients often have lymph node, bone, joint tuberculosis or other history of skin tuberculosis, and some occur after measles or other infectious diseases, tubercle bacilli can not be found in the rash, tuberculin test is positive, it is considered to be a type of tuberculosis In recent years, Brunner et al. have introduced cases of lichen-like or small papular sarcoidosis with clinical manifestations of spastic moss. Schuhmachers reported that 2 patients can be considered as generalized papular ring granulomas.
(two) pathogenesis
The pathogenesis is still not clear, tuberculosis can not be found in the rash, tuberculin test is positive.
Prevention
Spastic moss prevention
Precautionary principle: It is mainly to mobilize the masses, vigorously publicize the prevention and treatment knowledge of tuberculosis, conduct regular health checkups, early diagnosis, early treatment, eliminate infection sources, eliminate infection routes, carry out BCG vaccination, and enhance the body's resistance.
Complication
Spastic mossy complications Complications, tuberculosis
Tuberculosis spreads and causes tuberculosis in other parts of the body, such as tuberculosis (often with low fever, night sweats, history of wasting), peritoneal tuberculosis, lymph node tuberculosis, bone tuberculosis, kidney tuberculosis, etc., and further improvement of chest X-ray, B-ultrasound, and CT, MRI and other tests are comprehensively analyzed and determined to determine whether there are tuberculosis complications in the above-mentioned areas.
Symptom
Spastic mossy symptoms common symptoms scaly papules limbs mossy changes
The primary damage is reddish, reddish brown or yellowish brown and the hair follicles are the same as the miliary large papules, covered with fine scales, clusters of integrated pieces, scattered distribution, mostly in the chest, back, abdomen, waist and limbs, more common in the chest side Patients are often accompanied by other active tuberculosis, such as bone, lymph nodes, skin or visceral tuberculosis, especially in children, chronic, can be self-healing, easy to relapse, mild symptoms, high dilution of tuberculin (1:1000000) The test can be positive.
Examine
Examination of spastic moss
The tuberculin test can be positive.
Histopathology: Infiltration is mostly around the hair follicle. There are lymphocytes, epithelioid cells and Langhansian giant cells in the infiltration. The infiltration horizon is very clear.
Diagnosis
Diagnosis and identification of spastic moss
diagnosis
According to the clinical manifestations: the primary damage is reddish, reddish brown or yellowish brown and the hair follicles are the same as the miliary large papules, covered with small scales, clusters of integrated pieces, scattered distribution, mostly in the chest, back, abdomen, waist and limbs, to the chest The side is more common, patients are often accompanied by other active tuberculosis, such as bone, lymph nodes, skin or visceral tuberculosis, especially in children, chronic, can be self-healing, easy to relapse, mild symptoms, high dilution of tuberculin (1:1000000) The test can be positive, histopathology: infiltration around the hair follicle, infiltration of lymphocytes, epithelioid cells and Langhans giant cells, the infiltration horizon is very clear, can be diagnosed.
Differential diagnosis
1. Hair Moss: It occurs mostly on the extremities of the extremities, and is not arranged in clusters. The rash is consistent with the hair follicle mouth, and is embedded with horn plugs, which are covered with keratinous scales, and the mane is visible after removal.
2. Vitamin A deficiency: keratotic hair follicle papules embedded with horn plugs, hard nature, shaped like suede, dry skin, sparse hair follicles, nails are easily invaded, more common in the extremities of the extremities, often accompanied by Other vitamin A deficiency symptoms.
