PAEZ, RN; ANDREOLI, ML; GUARDATI, MV  y  IRIBAS, JL. FOLLICULITIS DECALVANS AND DISSECTING FOLLICULITIS.REPORT OF FOUR CLINICS CASES. Rev. argent. dermatol. [online]. 2019, vol.100, n.1, pp.26-42. ISSN 1851-300X.

The cicatricialalopeciasinclude a heterogeneous group of disorders that lead to permanent hair loss. Primary alopecias are distinguished, in which the hair follicle is the specific target of the destructive process, and secondary alopecias, that are the result of a non-specific destruction. Within the first group are the so-called neutrophilic type alopecias, consisting of the folliculitis decalvans and dissecting folliculitis or perifolliculitis capitis abscedens et suffodiens.

Four clinical cases are presented below, three of them being diagnosed with folliculitis decalvans and one with dissecting folliculitis, in male patients, aged between 21-39 years, having a delay in clinical-pathological diagnosis between 8 and 36 months. Among these, two obtained a good response to treatment with isotretinoin orally, while the other pair did not return to the consultation, so their evolution is unknown.This report motivates the need for an early diagnosis in order to offer patients a satisfactory therapeutic response, which does not occur in later stages.
