Perifollicular fibroma

Introduction to fibroids around the hair follicle The fibroids around the hair follicle (perifollicular fibromas) are often stained and dominantly inherited, and the disease is a hamartomatous hyperplasia of the hair connective tissue. It is characterized by fibrous hair follicle tumor, trichome tumor and soft cocoon in the face, neck and chest, and is associated with renal cell carcinoma, colon cancer, pulmonary cyst, medullary thyroid carcinoma and connective tissue spasm. It is an autosomal dominant genetic disease. basic knowledge The proportion of illness: 0.0005% Susceptible people: no special people Mode of transmission: mother-to-child transmission Complications: colon polyps fibrillar tumors

Causes of fibroids around the hair follicle

Causes:

The fibroids around the hair follicle are markedly inherited by the common stain, and the disease is a hamartomatous hyperplasia of the hair connective tissue. Fibroids around the hair follicle are characterized by concentricity of collagen fibers around normal hair follicles.

Pathogenesis:

The pathogenesis is still unclear.

Prevention of fibroids around the hair follicle

Early detection and early diagnosis and early treatment. A reasonable diet can take more high-fiber and fresh vegetables and fruits, balanced nutrition, including essential nutrients such as protein, sugar, fat, vitamins, trace elements and dietary fiber, with a combination of vegetarian and vegetarian foods. The complementary role of nutrients in food is also helpful in preventing this disease.

Complications around fibroids Complications, colon polyps, hair follicle tumors

Fibroids around the hair follicle may cause colon polyps, fibrous hair follicle tumors.

Symptoms of fibroids around the hair follicle Common symptoms Colon polyps papules

Lesions are single or multiple papules that occur in the face and trunk, and can be associated with colon polyps, fibroblasts, trichomes, and soft cocoons. This concomitant is considered to be Birt-Hogg-Dube syndrome. Case.

Examination of fibroids around the hair follicle

Histopathological examination of the lesions revealed the formation of cellular fibrous tissue in the dermis, concentrically arranged, forming an "onion skin"-like connective tissue sheath around the normal hair follicle. There are artificial fissures between the fibroids and the surrounding tissue.

Diagnosis and diagnosis of fibroids around the hair follicle

According to the clinical features of this disease, it should be differentiated from atrophic keratosis. Atrophic keratosis is a group of hereditary deficiency diseases, mainly characterized by keratinization followed by atrophy. It includes three types: facial atrophic keratosis, worm-like skin atrophy, and alopecia keratosis. It is also possible to overlap between types 3.
