Abstract
OBJECTIVE:
To report the clinico-histopathologic features, management and outcome of Rosai-Dorfman disease of the orbit.
DESIGN:
Non-comparative case series.
RESULTS:
Rosai-Dorfman disease of the orbit constituted 0.09% of all ocular specimens received at our Institute, presenting with a firm rubbery mass causing proptosis; bilateral in 4 (57%) cases. The median age at presentation was 13 years (range 5-65); median duration of symptoms was 6 (range 3-15) years. Lymphadenopathy was noted in 4 (57%); extranodal involvement in 3 (43%). After biopsy, 3 cases were treated with systemic corticosteroids, 2 cases developed local recurrence that responded to systemic corticosteroid therapy. Polymorphous population of lymphocytes, plasma cells, and characteristic S-100-positive histiocytes showing emperipolesis were pathognomonic histologic features.
CONCLUSION:
Rosai-Dorfman disease of the orbit, although rare, should be considered in young individuals with chronic proptosis with rubbery masses. Excision and corticosteroid therapy provide a favorable outcome.
