Characterized by the growth of granulomas, which are abnormal accumulations of inflammatory immune system cells called macrophages. Granulomas can appear in various parts of the body but are typically found in the lungs and lymph nodes.

Common Symptoms

Coexisting Diseases and Conditions

Hyperlipidemia, thyroid diseases, diabetes, bronchiectasis, neoplasm, osteoporosis, anemia, coronary heart disease, asthma, gastric/duodenal ulcers, allergy, sleep apnea, hypertension, chronic renal diseases, and COPD.

Risk Factors and Prevalence
