Cellulitis : Dissecting Cellulitis
Pediatric CellulitisThe pain in a pediatric cellulitis in an extremity is generally the presenting symptom. It is extreme and frequently out of ..... Dissecting cellulitis manifests with perifollicular pustules, nodules, abscesses and sinuses that emerges into scarring alopecia. It predominantly takes place in African American men between 20-40 years of age, but can sometimes affect other races and women too. Associated musculoskeletal findings are sometimes reported. When it happens with acne conglobata, hidradenitis suppurativa, and pilonidal cysts, the syndrome is referred to as the follicular occlusion triad or tetrad. Its course is chronic and relapsing, and treatment is very frequently difficult. Medical therapies comprise of isotretinoin, antibiotics, and prednisone. Destructive therapies comprise of X-ray therapy, surgical excision, and skin grafting. Laser epilation of hair follicles is a new therapy for dissecting cellulitis.
Dissecting cellulitis predominantly take place in African American men 20-40 years of age. It can rarely take place in males of other races and in women or girls. Familial cases have been reported. This condition has been reported in the Australian, French, British, Italian, and American literature. Dissecting cellulitis generally starts on the scalp vertex or occiput as a folliculitis. It spreads into patches of perifollicular pustules, nodules, abscesses and sinuses. Nodules might be firm or fluctuant and pus and serous fluid can be expressed. The course is generally chronic and relapsing. Different lesions can be present simultaneously and healing takes place with scarring alopecia that may be patchy or confluent. Often, keloidal scars lead into areas of inflammation.
Dissecting cellulitis can take place with acne conglobata, hidradenitis suppurativa, and pilonidal cysts, a syndrome referred to as the follicular occlusion triad or tetrad. It has been reported to take place with pyoderma vegetans, marginal keratitis, and pityriasis rubra pilaris. The pathophysiology is thought to engage follicular blockage in all these conditions. As material comprises in the follicle, the follicle dilates and then ruptures. Keratin and bacteria from the ruptured follicles can lead into a neutrophilic and granulomatous response. It likely represents a primary inflammatory procedure with secondary bacterial infection. Dissecting cellulitis must be distinguished from various other scalp conditions. The tendency of dissecting cellulitis to cause serious alopecia, fluctuant nodules, and sinus tracts helps to distinguish it from acne keloidalis nuchae. It varies from Pseudopelade of Brocq by its lack of atrophy and footprints in the snow alopecia morphology.
Streptococcal CellulitisStreptococcal cellulitis is most commonly caused by the streptococcus bacteria and the name itself is derived from the name of the .....
