Large cysts in the orbital lobe of the lacrimal gland are rare and are associated with Sjögren syndrome and B-cell mucosa-associated lymphoid tissue lymphoma. The authors describe 4 new cases of large orbital lobe lacrimal gland cysts. The first 2 patients, both with Sjögren syndrome, had unilateral cysts associated with chronic inflammation. Mucosa-associated lymphoid tissue lymphoma was also identified in the cyst wall of the second case and could not be completely excluded in the first case. The third patient, with a history of rheumatoid arthritis, had bilateral cysts, again associated with mucosa-associated lymphoid tissue lymphoma. The fourth patient, with no history of systemic disease, had a unilateral cyst associated with reactive lymphoid hyperplasia. Finally, the authors report the long-term outcomes of 3 previously reported cases.
In patients with chronic autoimmune disease, cysts of the orbital lobe of the lacrimal gland may be associated with lymphoid hyperplasia or mucosa-associated lymphoid tissue lymphoma.
