Treatment of folliculitis decalvans with tacrolimus ointment.

Folliculitis decalvans is an embarrassing and challenging disease with no established treatment guidelines. In this paper, we described four patients with this disease treated successfully with Tacrolimus ointment. All of them showed significant control of the condition, stopping inflammatory lesions and progression of the disease, although weak transitory outbreaks of inflammatory lesions were observed in some cases. Alopecia and tufted hairs remained unchanged. The discontinuation of the therapy produced rapid relapses in all cases. Close monitoring of these patients is recommended due to the potential risk of malignant transformation of the disease.
