Unicentric castleman’s disease in the posterior pleural cavity

Abstract

Introduction: Unicentric Castleman’s disease is a rare lymphoproliferative disorder. Patients are usually asymptomatic, anddisease is found incidentally on imaging studies. Although a benign condition, unicentric Castleman’s disease does increase therisk of other malignancies, and therefore, complete surgical resection is recommended. Here we report the case of a 48-year-oldsmoker who presented with an incidental lung mass.

Case presentation: A 48-year-old man presented to the hospital with a persistent cough in the setting of a 48-pack-year smokinghistory. A contrast-enhanced CT of the chest revealed a single pulmonary mass in the posterior chest cavity concerning formalignancy.

Conclusions: Unicentric Castleman’s disease can be a rare cause of a lung mass. Unlike primary lung malignancy, however,unicentric Castleman’s disease has an excellent prognosis.
