Dissecting cellulitis of the scalp presents as multiple firm, dome-shaped papules, which may coalesce to form plaques and nodules.69 Abscesses and sinus tracts may also be observed. The vertex and occipital area are most commonly affected. The disease is predominantly detected in men of African descent between 20 and 40 years of age. It may occur in association with acne conglobata, hidradenitis suppurativa (follicular occlusion triad), and pilonidal cysts (follicular occlusion tetrad).69,70
Pilonidal cysts
Published in Alisa McQueen, S. Margaret Paik, Pediatric Emergency Medicine: Illustrated Clinical Cases, 2018
Surgery. Pilonidal cysts are caused by an inflammatory process in the gluteal region. They are most common in 15- to 20-year-old males with a deep natal or intergluteal cleft. Other risk factors include obesity, sedentary occupation (>6 hours a day sitting down), poor hygiene with <3 baths per week, and extensive body hair. These clefts can get infected due to trapping of perspiration and moisture in the deep pockets. An infected pilonidal cyst needs to be treated. They can cause systemic symptoms such as fever, chills, and pain. A sinus tract can also develop, and when present there can be intermittent discharge of pus or blood. Chronic pilonidal cysts can have multiple sinus tracts. During workup, physicians need to consider possible anal fistula development and perianal Crohn’s disease. Management of these cysts involves antibiotics, pain control, surgery, and wound care. Antimicrobials should cover gram positive, gram negative, and anaerobic bacteria due to skin flora and close proximity to the anus. Hygiene is also very important in the treatment of these cysts. Baths need to be avoided while the wound heals and the use of handheld showerheads is recommended to be able to direct water to the site. Wounds must be cleaned after stooling and hair needs to be removed from wounds. Patients also need to be careful to avoid activities with excessive friction to the buttock such as cycling and driving/sitting for long periods.
Pilonidal Disease

William Mayo originally described a pilonidal cyst and associated abscess in the medical literature (1), but the disease was more popularized as “jeep’s disease” when the occurrence in World War II caused nearly 80,000 admissions and an average hospital stay of 55 days following surgical intervention (2,3).
Isotretinoin in the treatment of hidradenitis suppurativa: a retrospective study

Our data showed a 35.9% response rate to isotretinoin based on patients’ outcome assessment. A history of pilonidal cyst may be associated with a better treatment response. Larger prospective studies are needed to further investigate the effect of isotretinoin on HS, as well as the optimal dose and duration of treatment, particularly in patients with follicular occlusion tendencies.
