Miliary shadows on chest imaging have wide differential diagnoses. The most common etiology is infectious, such as miliary tuberculosis (TB) and histoplasmosis, but miliary shadows can be the presentation of sarcoidosis, pneumoconiosis, and secondary metastasis to the lungs from primary cancers of the thyroid, kidney, and trophoblasts as well as sarcomas. Here we present the case of a 35-year-old Indian male who presented with a 2-month history of dry cough and shortness of breath. Chest imaging showed diffuse bilateral miliary nodules. The initial impression was that of miliary pulmonary TB. Subsequent bronchoscopy with a transbronchial biopsy confirmed the diagnosis of pulmonary mucinous adenocarcinoma with brain metastasis, which is a rare and unusual presentation of primary lung cancer. The tumor was positive for ALK5A4 and PD-L1, and the patient was started on tyrosine kinase inhibitor immunotherapy, with a favorable response.

Sarcoidosis is a chronic multisystemic inflammatory disease of unknown aetiology. Virtually any organ or system can be involved, resulting in a wide range of clinical presentation. Pleural sarcoidosis is rare. Pleural effusion can only be attributed to pleural sarcoidosis in the presence of pleural non-caseating epithelioid granulomas and after excluding other granulomatous diseases. Anthracosis is a pneumoconiosis associated with thoracic adenopathies and bronchial disease, and it is usually asymptomatic. The authors present a case of a middle-aged man hospitalized due to cough, right-sided pleuritic chest pain and trepopnoea.

Background: Chronic beryllium disease (CBD) is a granulomatous disease that resembles sarcoidosis but is caused by beryllium. Clinical manifestations similar to those observed in CBD have occasionally been reported in exposure to dusts of other metals. However, reports describing the clinical, radiographic, and pathological findings in conditions other than beryllium-induced granulomatous lung diseases, and detailed information on mineralogical analyses of metal dusts, are limited. Case presentation: A 51-year-old Japanese man with rapidly progressing nodular shadows on chest radiography, and a 10-year occupation history of underground construction without beryllium exposure, was referred to our hospital. High-resolution computed tomography showed well-defined multiple centrilobular and perilobular nodules, and thickening of the intralobular septa in the middle and lower zones of both lungs. No extrathoracic manifestations were observed. Pathologically, the lung specimens showed 5-12 mm nodules with dust deposition and several non-necrotizing granulomas along the lymphatic routes. X-ray analytical electron microscopy of the same specimens revealed aluminum, iron, titanium, and silica deposition in the lung tissues. The patient stopped smoking and changed his occupation to avoid further dust exposure; the chest radiography shadows decreased 5 years later. Conclusion: The radiological appearances of CBD and sarcoidosis are similar, although mediastinal or hilar lymphadenopathy is less common in CBD and is usually seen in the presence of parenchymal opacities. Extrathoracic manifestations are also rare. Despite limited evidence, these findings are similar to those observed in pneumoconiosis with a sarcoid-like reaction due to exposure to dust other than of beryllium. Aluminum is frequently detected in patients with pneumoconiosis with a sarcoid-like reaction and is listed as an inorganic agent in the etiology of sarcoidosis. It was also detected in our patient and may have contributed to the etiology. Additionally, our case suggests that cessation of dust exposure may contribute to improvement under the aforementioned conditions.
