BACKGROUND: 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.
CASE PRESENTATION: 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.
CONCLUSIONS: 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.Free PDF Download
