ABSTRACT
Perifolliculitis capitis abscedens et suffodiens is a rare chronic recalcitrant follicular disorder which clinically presents itself as pulstules, nodules, intercommunicating abscess and sinuses that leave atrophic, hypertrophic or keloidal scars. Although the etiology of this of condition is unknown, its association with acne conglobata and hidradenitis suppurativa, collectively termed the follicular occlusion triad, suggest a cammon basic pathogenic mechanism of follicular retention. The therapeutic problem is reflected in the variety of therapies that have been tried with varying degrees of success. We report a case of a 34-year-old man who showed a patch of alopecia on the vertex of his scalp. Clinically, the scalp showed multiple soft fluctuant elevated nodules with nonscarring alopecic patches. We performed a treatment with isotretinoin(13-cis-retinoic acid) during 6 months. The patients clinical appearance was much improved and local recurrence and hair loss have not been observed to date.
