Silicoproteinosis is a rare disease, which can cause the rapid onset of respiratory failure following massive exposure to silica dust.A 25-year-old patient presented with altered state and dyspnea. The diagnosis of military pulmonary tuberculosis was first considered and antituberculous treatment was started. The diagnosis was reconsidered due to a lack of improvement and the discovery of an 18-month history of exposure to silica. The patient had stopped work 6 months prior to hospitalization. High-resolution CT showed air space condensation associated to centrilobular nodules throughout the lungs and multiple mediastinal lymph nodes, suggesting sarcoidosis. Bronchoalveolar lavage (BAL) suggested the diagnosis of lipoproteinosis. Because of discordance between the bacteriological, radiological and the BAL results, a surgical lung biopsy was performed which led to the diagnoses of a secondary lipoproteinosis. The diagnosis of silicoproteinosis was then considered. Over a one-year follow up, the patient's respiratory failure has progressed markedly despite treatment with corticosteroids.Silicoproteinosis is a distinct pathological entity, the diagnosis of which depends on clinical and radiological features as well as BAL findings, which may avoid the need for more invasive investigations.

Erasmus' syndrome involves the association of systemic scleroderma (SS) and exposure to silica. Silicosis may precede the SS but the latter may be the presentation, in which case a history of exposure to silica should be sought as part of the diagnosis.A 46-year-old man with history of pulmonary tuberculosis presented with dyspnoea and dysphagea. Clinical examination revealed thickening of the facial skin with a pointed nose, erythema and telangiectasia, Raynaud's syndrome and sclerodactyly. A thoracic CT scan revealed bilateral, fibrotic, pseudo-tumoural masses. Antinuclear antibodies, anti-topoisomerase 1 and antihistone were positive.The clinical presentation of Erasmus' syndrome associating systemic scleroderma and pulmonary pseudo-tumours may pose a problem of differential diagnosis from lung cancer. This condition requires regular clinical and radiological monitoring, particularly as both scleroderma and silicosis increase the risk of lung cancer.

We report a case of fistula between a silicotic mediastinal lymph node and the esophagus with protrusion of a stiff and darkish concretion into the oesophageal lumen. The patient, a 68-year-old coal miner, presented with cough since a few months and the lesion was revealed by haematemesis. The general course was rapidly favourable. Association with tuberculosis was recognized only a few months later.

Broncholithiasis is usually a late complication of tuberculous lymphadenopathy. Clinical symptoms are not suggestive of the condition in most cases, except for lithoptysis which occurs in 5 to 34% of the patients. Owing to the currently low frequency of tuberculosis, broncholithiasis is a rare and sometimes surprising diagnosis, as in the case reported here. In this 65-year old silicotic man, broncholithiasis was manifested by blood-stained expectoration. Fibroscopy established the diagnosis by showing 2 broncholiths, about 1 cm wide, which were endoscopically extracted. The second peculiarity of this case is that broncholithiasis was associated with active tuberculosis.
