Vagus nerve stimulation (VNS) is a surgical treatment available for patients affected by generalized refractory epilepsy. The authors report the case of a 15-year-old girl affected by CHD2-related myoclonic encephalopathy and BLM haploinsufficiency due to a deletion of 15q25.3q26.2 region, who suffered from secondary hemophagocytic lymphohistiocytosis (SHLH) after a VNS wound infection. SHLH has sporadically been described in epileptic patients. Based on indirect evidence that shows immune dysregulation in patients with CHD2 mutations and BLM mutations, we hypothesize that the genetic background of this patient may have played a critical role in the development of the syndrome.

Abstract
Vagus nerve stimulation (VNS) is a surgical treatment available for patients affected by generalized refractory epilepsy. The authors report the case of a 15-year-old girl affected by CHD2-related myoclonic encephalopathy and BLM haploinsufficiency due to a deletion of 15q25.3q26.2 region, who suffered from secondary hemophagocytic lymphohistiocytosis (SHLH) after a VNS wound infection. SHLH has sporadically been described in epileptic patients. Based on indirect evidence that shows immune dysregulation in patients with CHD2 mutations and BLM mutations, we hypothesize that the genetic background of this patient may have played a critical role in the development of the syndrome.
