Background:
Sarcoidosis is a multi-system, idiopathic, inflammatory disorder that affects the lungs in over 90% of patients. The incidence of bone lesions in sarcoidosis is only 1-13%.
Case Report:
This study describes a 60-year-old woman with a previous history of thyroid cancer, and a more recent diagnosis of lung cancer with suspicious metastatic lesions, which were confirmed to be sarcoidosis.
Conclusion:
This case suggests that pulmonary neoplasms and pulmonary sarcoidosis can coexist and be easily confused. When lung cancer is accompanied by symmetric hilar lymph node enlargement and multiple lung nodules, sarcoidosis should be considered in addition to metastasis, and a biopsy should be performed for confirmation.
