Lichen simplex chronicus on the scalp, also known as trichoteiromania, can be difficult to manage, as the therapeutic options are limited to topical or intralesional glucocorticoids. We describe a patient with trichoteiromania, presenting three lichenified pruriginous plaques on different regions of the scalp, associated with fracture and loss of hair shafts. Prior treatment with potent topical glucocorticoids was ineffective. However, treatment with oral N-acetylcysteine (NAC) 1,200 mg/day resulted in complete hair regrowth within 16 weeks. NAC is a safe drug with a good tolerance profile that could be a therapeutic option for patients with trichoteiromania. The potential of NAC has not been completely elucidated, thus more studies will be necessary to confirm its efficacy in the long term for some psychodermatological conditions.

“…In this case, trichoscopy showed features of FFA associated with a feature previously described in LSC – broom hair fibers [3, 8]. As was the case in another report, the absence of other trichoscopic features of TTM and the presence of lichenification distinguishes LSC from TTM.…”

“…Broom hairs are short hairs with a proximal breakage into two or three shafts and others with additional breakage at the distal tips into two or three shafts. These have also been reported in trichotillomania (TTM) [4], and, according to Quaresma et al [3], the absence of other trichoscopic features of TTM and the presence of lichenification distinguishes these two disorders.…”

“…Lichen simplex chronicus (LSC) is a recalcitrant skin disease characterized by lichenified patches, commonly located in the neck, ankles, scalp, and anogenital region [1-3]. It occurs as a result of constant scratching or rubbing of the skin and has been reported in the setting of other disorders such as atopic dermatitis, anxiety, or pruritus related to systemic disease [1, 2].…”
