Castleman's disease of the lacrimal gland.

Castleman's disease, also known as angiofollicular lymphoid hyperplasia, is a lymphoproliferative disorder that is generally benign. The lesions most commonly originate in the lymph nodes of the mediastinum. The second documented case of Castleman's disease of the lacrimal gland is reported in an 84-year-old woman who presented with an 8-year history of a left upper lid mass. This was excised via a lateral orbitotomy, and a diagnosis of Castleman's disease was made histologically. Relevant images of the clinical findings and histology are shown.
