Toxic epidermal necrolysis: case reportA 33-year-old woman who had received carbamazepine for

postnatal depression developed toxic epidermal necrolysis(TEN) which responded to treatment with IV immunoglobulin(IVIG).

Two days after starting treatment with oral carbamazepine[dosage not stated] and venlafaxine the woman developedconjunctivitis followed, 9 days later, by urogenital ulceration. Afurther 2 days later, widespread targetoid lesions appeared onher face, trunk and proximal limbs, with blisters developinginitially on her trunk.

Carbamazepine and venlafaxine were discontinued and thewoman was admitted to hospital. Over the following few daysher rash became more severe with widespread erosions. Askin biopsy showed a subepidermal blister and there was amild, mainly lymphohistiocytic, inflammatory infiltrate in thedermis and full thickness necrosis of keratinocytes, consistentwith a diagnosis of TEN. She received topical betamethasonevalerate ointment and IV benzylpenicillin and flucloxacillin, buther condition deteriorated with extensive skin involvementand, 4 days after admission, she was transferred to the burnsunit. Examination revealed widespread blistering anddesquamation over her face, neck, trunk, proximal limbs andmucosal surfaces, affecting 70% of her body surface area. Shealso had periorbital oedema and 4–5mm central cornealerosions in both eyes.

Human IVIG was started and continued for 4 consecutivedays and the woman also received topical clobetasol, silversulfadiazine, skin soaks, oily cream and gauze dressings, abeclomethasone gargle and amphotericin lozenges, anddexamethasone eye drops. She showed significantimprovement 2 days after starting IVIG, with cessation ofepidermal detachment, the development of areas of re-epithelialisation and resolution of chemosis. Two days aftercompleting IVIG therapy, all her desquamated areas had re-epithelialised and, 7 days after admission to the burns unit, shewas transferred back to the ward.
