Angioimmunoblastic T-cell lymphoma with exuberant plasmacytosis and spontaneous tumor lysis syndrome.

We present a 67-year-old man with complaints of confusion, chills, night sweats, and several days of poor oral intake. He had severe plasmacytosis on lab work, which initially raised concern for plasma cell leukemia. However, further workup led to the diagnosis of angioimmunoblastic T-cell lymphoma. His initial hospital course was complicated by spontaneous tumor lysis syndrome. Early recognition and prompt interventions are pivotal to improve survival outcomes in such patients.
