Sarcoidosis presenting pulmonary subsolid nodules that mimic lung adenocarcinoma in a patient with history of uveitis and arrhythmia: a case report
Sarcoidosis is an idiopathic systemic granulomatous disorder that can involve any organ, although the lung is the most commonly affected site; moreover, it may affect multiple organs simultaneously or serially over a long time span. Diagnosing sarcoidosis can be a challenge in cases presenting an isolated extra-thoracic lesion at the early stage of disease. Pulmonary nodular lesion, a rare radiologic finding, may also lead to delayed diagnosis of sarcoidosis. We reported a case of atypical pulmonary nodular sarcoidosis that was suspected as lung adenocarcinoma, which was diagnosed about 20 years after initial isolated extra-thoracic manifestation occurred.
