Castleman Disease : An Unexpected Cause of a Solitary Pleural Mass

الملخص EN

Castleman disease (CD) is a rare benign lymphoproliferative disorder, the etiology of which is unclear.

Clinically it may manifest as localized disease (unicentric) or disseminated disease (multicentric).

CD occurs in the thorax in 70% of cases, abdomen and pelvis in 15%, and in the neck in 10–15% of cases.

We present a case of a pleural mass located posteriorly in a paraspinal location, which was discovered incidentally in a 50-year-old man and was subsequently resected followed by an unexpected diagnosis of Castleman disease on histological examination.

In this report, we review the clinical and histological findings in a rare presentation of Castleman disease and discuss the findings in this case as part of an overall review of the typical radiological findings seen in Castleman disease.
