This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Sarcoidosis, Subject name: Pathology
All of the following statements are false regarding sarcoidosis, except: 
Select and explain. 
A. Schaumann bodies and asteroid bodies are not seen, B. BAL (broncho-alveolar lavage) fluid shows CD8/CD4 T cell ratio of 4:1, C. Hilar and mediastinal lymph nodes are spared, D. Can be associated with unilateral or bilateral iritis or iridocyclitis
D: Can be associated with unilateral or bilateral iritis or iridocyclitis
Answer: D: Can be associated with unilateral or bilateral iritis or iridocyclitis 
Explanation: Sarcoidosis The lungs are involved is seen in 90% cases. Clinical manifestations include lymph node enlargement, eye involvement (sicca syndrome , iritis, or iridocyclitis), skin lesions (e.g., erythema nodosum), and visceral (liver, skin, marrow) involvement. Lymph nodes are involved in almost all cases, paicularly the hilar and mediastinal nodes. Intra-alveolar and interstitial accumulation of CD4+ T cells, resulting in CD4/CD8 T-cell ratios ranging from 5:1 to 15:1. Schaumann bodies and asteroid bodies are seen on microscopic examination. These are not pathognomonic of sarcoidosis because these may be seen in other granulomatous diseases (e.g., tuberculosis).
