Miliary sarcoidosis is a rare form of sarcoidosis characterized by numerous miliary-like micronodules dispersed throughout the lungs. It has been documented in less than 1% of all sarcoidosis cases. We first described a rare case of miliary sarcoidosis and then conducted a literature review on the subject.A 51-year-old male complained about a progressive loss of appetite, significant weight loss, occasional night sweats, and fatigue. After a thorough clinical exploration, a differential diagnosis of miliary lung disease was suspected - miliary tuberculosis, fungal infection, metastatic pulmonary carcinoma, or sarcoidosis. High-resolution chest computed tomography revealed bilateral diffuse micronodules with mediastinal lymphadenopathy. Histopathological analysis of transbronchial bioptic tissue identified non-caseating epithelioid granulomas, while no malignant cells were found. Lung tuberculosis and fungal infections were excluded. The levels of angiotensin-converting enzyme in the blood, as well as serum's and 24-hour urine calcium levels, were elevated. After a multidisciplinary discussion, the diagnosis of miliary pulmonary sarcoidosis was established. The patient was treated with prednisone for a total of 9 months, with full clinical and radiological recovery. Using PubMed, we also conducted a review of the literature on this topic and discovered only a few case reports of patients with miliary sarcoidosis, with just one systematic review accessible. The key findings of studies investigating patients diagnosed with miliary sarcoidosis are tabularly displayed.Miliary sarcoidosis is an uncommon type of pulmonary sarcoidosis that can mimic several entities that manifest as miliary nodules. Most patients require treatment since it can have a significant impact on lung function. |
