He presented in May of 2009 for another opinion. He has had a few cysts of the axillae and chin. The patient has observed that his scalp is worse after wearing a helmet for football.

Diagnosis: Dissecting Cellulitis of the Scalp in the setting of Follicular Triad Syndrome. An older name for the scalp process is the hard to remember "Perifolliculitis Capitis Abscedens et Suffodiens

Treatment: To date, only doxycycline 100 mg b.i.d. and frequent excisions by a plastic surgeon. I injected some active lesions with triamcinalone acetonide 10 mg/cc and am considering following the rifampicin and isotretinoin protocol reported in the reference below.

Reason Presented: For therapeutic suggestions

Dissecting cellulitis of the scalp, or perifolliculitis capitis abscedens et suffodiens, is an uncommon chronic suppurative disease of the scalp manifested by follicular and perifollicular inflammatory nodules that suppurate and undermine, forming intercommunicating sinuses, and leading to scarring alopecia. Treatment generally fails to obtain a permanently successful result; thus, many therapeutic options have been proposed. We report 4 cases of dissecting cellulitis of the scalp successfully treated with oral rifampicin and oral isotretinoin. To our knowledge, this is the first report of oral rifampicin used concomitantly with oral isotretinoin in this disease entity. We also present a brief review of the literature on the topic.

    The optimum treatment of this case is to start a combination of systemic steroids 25 mg daily for 1 month and isotretinoin 40 mg per day for 1 year

    In my openion,this a varient of sever cystic acne similar to apocrine acne.I see few cases a year and treat them as acne mainly by using oral sulaphamaxisol( seprin)oral pednisolone 5mg/day,topical dalacin c 1% solution and oral isotretinoinThere is no need for excision at all.Intralesional steroid injection might be tried.

  3. I've had some success with prolonged courses of rifampicin / clindamycin (300 mg bd for each drug x 6 months).

  4. Just a thought-- I was recently working alongside a visiting dermatologist from Brazil and she reported some success using finasteride to treat recalcitrant hidradenitis suppurativa-- I looked into this and there are indeed some reports in the literature supporting this. Could finasteride possibly play a role in pt's with dissecting cellulitis of the scalp?

    We did recenly a study where we found that spironolactone was much more effective than finasteride in treatment of acne.Accordingly we recommend to use spironolactone in mangement of acne,apocrine acne,and dissecting cellulitis.

  6. in my opinion treatment should be

    doxycycline 100 mg twice daily + rifampicin 300 mg twice daily + prednisolone in a low dose + oral isotretinoin
    intralesional triamcinolone could also be tried in active or resistant lesions.
