Autoimmune oophoritis associated with polycystic ovaries.

Autoimmune oophoritis is a rare cause of premature ovarian failure. Previous histological descriptions are sparse, with even fewer reports of cystic ovaries associated with this condition. Two cases of autoimmune oophoritis presenting as cystic ovaries with menstrual abnormalities are described, with immunocytochemical analysis of the inflammatory cell infiltrate. Serum autoantibodies to ovary and adrenal were present in both cases. Although rare, recognition of the condition by histopathologists is important because of the strong association with other 'organ-specific' autoimmune diseases, especially idiopathic Addison's disease. A review of the 17 reported cases indicates five where cystic changes were present in the ovary.
