We report on a 22-year-old assistant cook, presenting with seizures evoked by immersing his right hand into hot water of 40-46 degrees C. His seizure pattern consisted of either simple partial seizures of a tingling sensation arising in the right hand and marching to the right shoulder or a similar attack evolving to a complex partial seizure. Video-EEG monitoring recorded habitual seizures originating from the left centro-temporo-parietal region, compatible with lesions seen on brain magnetic resonance imaging. He responded well to antiepileptic drug treatment and wearing gloves while working in the kitchen. In this patient, hot water of 40-46 degrees C could maximally stimulate skin warm thermoreceptors in the right hand whereby afferent impulses subsequently activated the epileptogenic focus, adjacent to or in the sensory cortex, and elicited seizures.
