Multimodal imaging of sarcoid choroidal granulomas
BACKGROUND Enhanced-depth imaging optical coherence tomography (EDI-OCT) provides high-resolution imaging of the choroid. Herein, we report multimodal imaging, including EDI-OCT, of a case of sarcoid choroidal granulomas. FINDINGS A 63-year-old female with biopsy-supported sarcoidosis presented with unilateral multifocal choroidal granulomas. Enhanced-depth imaging optical coherence tomograph...
متن کامل"Residual bodies" in sarcoid and sarcoid-like granulomas.
A MORPHOLOGICAL AND HISTOCHEMICAL STUDY WAS MADE OF EPITHELIOID CELL GRANULOMAS: (a) classical sarcoid type, namely, sarcoidosis, Kveim tests, tuberculosis, farmer's lung, and Crohn's syndrome; (b) sarcoid-like granulomas, often distinguishable from (a) by the presence of extracellular mucin or bile, namely, ulcerative colitis, diverticulitis, cholecystitis, cholangitis, carcinoma of the rectum...

متن کاملSarcoid-like lung granulomas in a hemodialysis patient treated with a dipeptidyl peptidase-4 inhibitor
It has been reported that the inhibition of dipeptidyl peptidase-4 (DPP-4)/CD26 on T-cells by DPP-4 enzymatic inhibitors suppresses lymphocyte proliferation and reduces the production of various cytokines, including tumor necrosis factor (TNF)-α. A 72-year-old female with diabetic nephropathy on hemodialysis developed multiple lung nodules following the administration of vildagliptin. A biopsy ...
متن کاملThe fine structure of sarcoid and tuberculous granulomas.
The granulomas of sarcoidosis and non-caseating tuberculosis show similar cell-types: two forms of epithelioid cells, A and B, giant cells, lymphocytes and 'activated' mononuclear cells. The morphology of epithelioid cells suggests that they are primarily biosynthetic rather than phagocytic. The relationship of these various cells to each other is discussed and the following sequence of granulo...
