Abstract
A miliary nodular pattern of the lungs is an unusual presentation of sarcoidosis. Diagnosis of this condition can be challenging and requires exclusion of other lung pathology. A 47-year-old African American male presented to his doctor with a complaint of unintentional weight loss, exertional dyspnea and cough. The patient had a history of chronic smoking as well as recent incarceration. A miliary nodular pattern was found on CT scan of the lungs in a random distribution (with prominent peri-lymphatic distribution). HIV was ruled out. Tuberculosis (TB) and fungal infections were ruled out by tissue specimens and cultures from bronchoalveolar washings. Non-caseating granulomas on tissue specimens, peripheral smear lymphopenia and an elevated angiotensin converting enzyme (ACE) level were the positive findings on pathology and labs. The patient responded to a tapering course of oral steroids. This case demonstrates one of the unusual clinical presentations of sarcoidosis. Sarcoidosis is an autoimmune condition with predilection for middle aged African American patients.
