A case report of orbital Castleman’s disease

Castleman's disease is a group of atypical lymphoproliferative disorders. Extranodal involvement is rare. We report a case of a 39-year male who had left painless proptosis for three months. Examination revealed a firm mass in the left inferior orbit, displacing the globe superiorly. MRI showed an irregular mass causing enlargement of the left recti muscles. Systemic workup was unremarkable. The mass was excised via inferior orbitotomy. Histopathology showed hyaline vascular variant of Castleman's disease. Postoperatively, proptosis resolved and no recurrence was noted. This highlights the importance of including CD while evaluating irregular orbital lesions for early detection and management.
