Figure 3: Clinical images in sarcoidosis. Bilateral lacrimal gland enlargement seen in a patient with sarcoidosis, right eye (A) and left eye (B) . (C) Multiple erythematous plaques with superficial epidermal atrophy on exposed areas and sparing of nasolabial folds. The differentials include rosacea and lupus erythematosus. (D) Swollen left knee joint (thick arrow), synovial thickening of right knee joint (thin arrow). Synovial biopsy revealed non-caseating granulomas compatible with sarcoidosis. (E) Erythematous, tender nodules over extensor aspect of both legs suggestive of erythema nodosum, a non-specific cutaneous lesion in sarcoidosis, (F) Erythematous barely elevated plaque with well-defined margins developed on a scar over forehead (arrow). Skin biopsy revealed non-caseating granulomas. This condition is known as scar sarcoidosis and may be mistaken for keloids.
