Unilateral adrenal Castleman's disease: A case report

Castleman disease (CD) is a heterogeneous hematological condition characterized by distinctive histopathological features. The etiology remains unclear, and clinical symptoms are generally nonspecific. CD can occur in any location containing lymphatic tissue, with the mediastinum being the most common site, while adrenal involvement is rare. Adrenal CD is typically incidentally discovered during physical examination, commonly affecting one side. Imaging studies often make it challenging to differentiate from common adrenal tumors, necessitating pathological confirmation. Surgical intervention is the preferred treatment, and the prognosis is generally favorable.

This paper presents a rare case of a left adrenal mass, which was diagnosed as Castleman disease following surgical resection.
