Toxic epidermal necrolysis secondary to angioimmunoblastic T-cell lymphoma.

A 67-year-old man presented with a history of lymphadenopathy, fevers and separate skin eruptions of erythrodermic spongiotic dermatitis initially and subsequent toxic epidermal necrolysis. Initial lymph node biopsies showed non-specific granulomatous changes, and skin biopsies and bone marrow aspirate were not diagnostic. His toxic epidermal necrolysis responded well to 3 days of intravenous immunoglobulin. The patient was discharged from hospital and reviewed regularly as an outpatient. Due to persisting lymphadenopathy, further lymph node biopsy led to the diagnosis of angioimmunoblastic T-cell lymphoma, a rare form of peripheral T-cell lymphoma with a poor prognosis. At the time of diagnosis his condition deteriorated rapidly and he died soon after.
