suboccipital induration folliculitis
Introduction
Introduction to suboccipital induration folliculitis Suboccipital indwelling folliculitis (suboccipitalindurative folliculitis) is a chronic induration and scar dermatitis that occurs in the suboccipital and middle parts of the occipital bone. It is caused by Staphylococcus aureus and the like. It is mainly caused by inflammation around the hair follicle and connective tissue. Papillary dermatitis, occipital papillary dermatitis, keloid folliculitis, keloid acne or item sore. After the initial pillow or in the item, there are many red hair follicle papules of miliary size, the papules gradually increase, the deep purulent fusion, the connective tissue hyperplasia, and the formation of papillary scars. It may have itching or pain. This disease often persists and requires comprehensive treatment of systemic and local. basic knowledge The proportion of illness: 0.004%-0.007% Susceptible people: no specific population Mode of infection: non-infectious Complications: impetigo
Cause
Causes of suboccipital induration folliculitis
(1) Causes of the disease
The exact cause of the disease is unknown, but most people believe that infections from Staphylococcus aureus and streptococcus, coupled with the frictional stimulation of the collar, make folliculitis difficult to cure, inflammation continues to develop deep and around the hair follicle, and the body's special response State (scarring tendency), causing local connective tissue hyperplasia, forming scars.
(two) pathogenesis
Mainly foreign body small body granuloma changes, from folliculitis to inflammation around the hair follicle, hypertrophic connective tissue bundle and plasma cell infiltration instead of the damaged normal structure.
Prevention
Suboccipital induration folliculitis prevention
Enhance the body's resistance, pay attention to personal hygiene, keep the skin clean, avoid trauma, scratch and other bad habits.
Complication
Complications of suboccipital induration folliculitis Complications, impetigo
Generally no complications.
Symptom
Inferior occipital inflammatory folliculitis symptoms Common symptoms Hypertrophic scar Skin itching Hair shedding Papular abscess Nodule pustule
This disease involves the young and middle-aged neck of the hairline up and down, accidentally involving other parts of the scalp, the initial damage is located in the middle of the item or under the occipital bone, the miliary size of the red hair follicle papules, gradually expanding along the hairline of the posterior occipital region. Fusion, forming irregular strips or groups of different sizes of nodules, the surface is tense and shiny, uneven, hard to touch, occasionally a small amount of pus overflow, the hair follicles are blocked by sebaceous glands or The blackhead is blocked, where the hair is sparse, and a few hairs can be seen from a pore into a bundle. Small pustules can also appear. The development of the lesion can form an abscess and a sinus filled with pus, like the lobulation of the scalp. Cellulitis, and finally the formation of uneven hypertrophic scars, more common under the occipital bone, the course of the disease is slow, often for several months or years.
Examine
Examination of suboccipital induration folliculitis
Bacterial culture and drug susceptibility test have guiding significance for clinical drug use.
Diagnosis
Diagnosis and diagnosis of suboccipital induration folliculitis
Diagnosis based on medical history and clinical manifestations is generally not difficult.
Identification with lupus vulgaris, the latter has lupus nodules and ulcers, slides are "apple sauce color", soft texture, probe penetration phenomenon, histopathological examination of dermal superficial tuberculous nodules, lymphocytes, epithelium The infiltration of the like cells and macrophages is dominant.
