angiofibroma of the face
Introduction
Introduction It is common between 3 and 10 years old, sometimes even later, and becomes more extensive during puberty, and remains unchanged thereafter. Often tough, scattered yellow telangiectasia papules, 1 to 10 mm in diameter, extending from the nasolabial fold to the lower cheek and the neck, or between the ears, the number is large and obvious, and in rare cases can form large Cauliflower lumps. Most patients are limited to the sides of the nose or lower jaw and are therefore easily overlooked.
Cause
Cause
The widespread organocytosis depends on the primary defects of connective tissue, and there is excessive collagen in the skin lesion area, and there is no special change in the patch area of the carp skin. The so-called sebaceous gland adenoma can have hyperplastic blood vessels, sebaceous glands or immature hair follicles. Periungual fibroids have only vascular fibrous tissue. Abnormal pigment cells with low tyrosinase activity in the leafy white patch area.
Characteristic sclerosing nodules of gliosis appear in the cerebral cortex, basal nodules, and ventricular wall, but are rarely seen in the cerebellum, cerebral ventricle, or spinal cord. Glioma is often seen and often occurs in the striatum thalamic area. About 80% of autopsy cases can be seen in embryonic kidney tumors, often multiple, located under the cortex and benign. The so-called congenital heart rhabdomyosarcoma is an abnormal embryonic myocardium and prematurely differentiates into atypical Purkinje cells. The lungs may be interstitial fibrosis or fibrosarcoma with cystic changes.

When the disease is present, the diagnosis is not difficult. It can be differentiated from acne vulgaris according to the telangiectasia, blackheads and pustules of this disease. The disease should also be differentiated from the tough skin color papules of cystic adenoid epithelioma.
Diagnosis
Differential diagnosis
Facial angiofibroma needs to be differentiated from the diseases above.
1. Fibrous papulosis: is an angiofibromatous change that was previously thought to be melanin.
2. Hair epithelioma: Hair epithelioma is also known as cystic adenoid epithelioma, multiple benign cystic epithelioma and multiple papular epithelioma. This tumor line originates from a benign tumor of the hair. Multiple hair style cases are related to heredity, mostly autosomal dominant inheritance, but single-hair styles have no family history. Habitually, cystic adenoid epithelioma refers to multiple hair lesions, while hair epithelial tumors can refer to single and multiple lesions. It is generally believed that such tumors originate from pluripotent basal cells and have a tendency to differentiate into hair.
3. Polymorphic fibroids: a benign tumor of fibrous tissue that occurs in the skin and has pleomorphic and atypia in the nucleus of the tumor. Common in the skin of the limbs, also seen in the trunk and head and face.
4. Hairy fibroids: The hair follicles are dilated or normal, filled with horny matter, and there are immature collagens arranged in concentric circles around the hair follicles.
5. Acne: commonly known as acne, acne, acne, ancient Chinese called sore, wine thorn. It is a common disease in dermatology and is frequently afflicted. According to scholars, 95% of men in adolescence and 85% of women have different degrees of acne. So everyone calls it "acne" is very appropriate. Acne (acne) is a chronic skin disease that occurs in the sebaceous glands of the hair follicles. It is often found in the head and face, the neck, the back of the chest, and other parts of the sebaceous glands.
When the disease is present, the diagnosis is not difficult. It can be differentiated from acne vulgaris according to the telangiectasia, blackheads and pustules of this disease. The disease should also be differentiated from the tough skin color papules of cystic adenoid epithelioma.
