Introduction
Dravet syndrome, also called severe myoclonic epilepsy in infancy. This disorder usually manifests in the first year as febrile or afebrile clonic and tonic–clonic, generalized, and unilateral seizures, often prolonged, in an apparently normal infant. Later, multiple seizure types, mainly myoclonic, atypical absences, and focal seizures appear, as well as a slowing of developmental and cognitive skills, and the appearance of behavioral disorders. Up to 80% of patients are tested positive for SCNA1 mutation.1 Dravet syndrome is usually accompanied by many comorbidities including psychiatric issues, urinary tract and bowel issues, sleep disorders and others.2 Here, we describe an adolescent with Dravet syndrome who was diagnosed with B-cell type acute lymphoblastic leukemia (ALL) and suggest a possible correlation between these two disorders.
