Differential diagnosis: Repetitive behaviors, such as skin picking and hair pulling, should be differentiated from stereotypic movement disorders that may occur in the setting of certain neurodevelopment disorders and an autism spectrum disorder. Other psychocutaneous disorders should be excluded, including delusions of infestation and factitial dermatitis. If pruritus is present, primary causes such as systemic diseases or adverse effects from medications or illicit drugs should be ruled out. Dermatoses that may cause abnormal skin sensation and/or pruritus should be evaluated for including, but not limited to, eczema, psoriasis, and prurigo nodularis. If the face is affected, the trigeminal trophic syndrome should be considered in the correct clinical context.

Trigeminal trophic syndrome is a rare disease that has significant morbidity. Diagnosis of TTS may be difficult and is considered to be a diagnosis of exclusion (1). Lack of infectious, neoplastic, or vasculitic etiology on H&E, as well as a history of trigeminal nerve injury, and classic involvement of nasal ala help to make this diagnosis (4). Sparing of the nasal tip due to sensory innervation by the external branch of the anterior ethmoid nerve can also help distinguish TTS from other central facial ulcerations (1,2).

Trigeminal trophic syndrome (TTS) is a condition whereby persistent facial ulceration presents consequent to central or peripheral insult to the trigeminal nerve. Lesions are created by repetitive self-inflicted manipulation and trauma of dysaesthetic skin within the trigeminal dermatome.
