Trigeminal trophic syndrome (TTS) is a rare condition that results from a prior injury to the sensory distribution of the trigeminal nerve. Patients typically respond to the altered sensation with self-mutilation, most often of the nasal ala. We describe 3 patients with TTS who presented with self-induced ulcerations primarily involving the scalp. Two patients developed delusions of parasitosis (DOP) based on the resulting symptoms of TTS, which is a unique association. Trigeminal trophic syndrome may occur at extranasal sites and in any branch of the trigeminal nerve. The condition should be considered when ulcers are encountered in this nerve distribution. Symptoms such as formication may mimic DOP. Trigeminal trophic syndrome may be differentiated from DOP by the restriction of symptoms and ulcerations to the distribution of the trigeminal nerve.
三叉神经营养综合征（TTS）是一种罕见的疾病，由三叉神经感觉分布区先前的损伤引起。患者通常会因感觉改变而进行自我伤害行为，最常见的是鼻翼自残。我们描述了3例以主要累及头皮的自我诱发溃疡为表现的TTS患者。两名患者基于TTS产生的症状出现了寄生虫妄想症（DOP），这是一种独特的关联。三叉神经营养综合征可能发生在鼻外部位以及三叉神经的任何分支。当在该神经分布区域遇到溃疡时，应考虑此病。蚁走感等症状可能会模仿DOP。三叉神经营养综合征可通过症状和溃疡局限于三叉神经分布区与DOP相鉴别。
