A 16-year-old female student presented with absence seizures for 2 years of age and no significant past or family history of epilepsy or allergic disorder. The computerized tomography (CT) head and magnetic resonance imaging (MRI) of the brain were found to be normal; electroencephalography (EEG) was abnormal with diffuse cerebral dysfunction. She had been treated with clobazam 10 mg/day OD, for 1.5 years, but was still experiencing seizures about one to two in a day; therefore, LTG was added, starting with 25 mg a day, with weekly escalation, up to a dose of 100 mg/day. After 2 weeks of adding LTG, she developed fever, headaches, chills, and rash all over the body; the patient presented to the dermatology outpatient department (OPD) after 1 week of onset of the symptoms.\nOn examination, maculopapular lesions involving the genitals associated with itching were seen, which then spread to the trunk and then extremities in the next 3 days []. They became tender, and the erythematous, partially blanchable lesions took on a dusky hue over the trunk, upper limb, lower limb, and progressed to involve the face and lips (crusted plaques). No involvement of the oral cavity was noted nor were there any vesicular lesions. On the basis of history and clinical examination, a diagnosis of TEN was made and LTG was discontinued immediately and admitted under the dermatology department. LTG was stopped, and she was started on levetiracetam 500 mg twice a day, continued on clobazam 10 mg/day, intravenous steroids, fluids, and antibiotics. With medications and supportive care, the patient improved without any further complications.
A 16-year-old boy, known case of juvenile myoclonic epilepsy, presented to the neurology OPD with generalized maculopapular rash [], fever, and facial puffiness. He was on LTG 250 mg TDS, clobazam 10 mg OD, and valproate 200 mg (morning) 400 mg (evening) for 1 year. Subsequently, he developed erythematous rashes over the face, neck, trunk, arms, and legs followed by painful ulcers in the oral cavity and encrustations on the lips. History revealed that no such lesions occurred earlier. His neurological examinations, CT head and MRI, were found to be within normal limits. EEG was abnormal and suggestive of generalized epilepsy. Physical examination showed multiple round erythematous plaques on the face, neck, trunk, and extremities, some of which were tender. On oral examination, there was limited mouth opening and erythematous crusted areas on both the lips due to inflammation and ulceration. Based on the history and clinical presentation, a diagnosis of SJS was made. As the Pre-assumption was LTG, the drug was withdrawn immediately and the dose of clobazam was increased. The patient was admitted to dermatology ward and treated with cyclosporine and methylprednisolone and intravenous fluids. His condition improved during the next 2 weeks; he eventually recovered and continued follow-up on an outpatient basis.
