Pneumoconiosis is a systemic disease involving pulmonary interstitial fibrosis caused by long-term inhalation and retention of dust, generally as a result of occupational exposure. It has become one of the most serious occupational diseases, ranking as the highest with respect to incidence in China [1]. According to data from the Ministry of Health, nearly 700,000 cases of pneumoconiosis were r...

BACKGROUND Adenocarcinoma with lepidic growth pattern presents as a ground glass nodule (GGN) on high resolution computed tomography (CT), whereas peripheral pulmonary squamous cell carcinoma (SCC) usually presents as a solid nodule. We herein report a rare case of pulmonary SCC extending along the alveolar lumen representing as a GGN on a CT scan in a patient with pneumoconiosis. CASE PRESEN...

Pneumoconiosis is a notifiable industrial disease where a patient develops the disease, their doctor must notify their employer in writing with the patient's consent. The employer then is duty-bound to inform the local Health and Safety Executive (HSE). Pneumoconiosis is also a prescribed industrial disease. Financial compensation may be available where an individual is able to show they worked...

A fuller's earth worker developed signs of pneumoconiosis. Pathological examination of the lung tissues showed interstitial collections of dust laden macrophages associated with mild fibrosis. Mineralogical analysis showed a high content of montmorillonite. This study shows that a pneumoconiosis can result from prolonged heavy exposure to calcium montmorillonite (fuller's earth) in the absence ...

Limestone dust is generally regarded as being relatively harmless. In this paper I wish to record eight cases of pneumoconiosis in limestone workers, in all of which limestone played the sole or principal aetiological part. My attention was first drawn to the condition in November, 1950, when I saw the chest radiograph of a patient whose occupation was limestone crushing. The appearances were m...

Coalminers' pneumoconiosis may be complicated by the development of progressive massive fibrosis (PMF) or by rheumatoid pneumoconiosis (Caplan's syndrome).'2 The arthritis in Caplan's syndrome may precede, coincide with, or follow the development of pulmonary radiological shadows. These conditions are common in miners and may be seen in workmen exposed to dusts other than coal.' The Fujian Shao...

Chronic exposure to high concentrations of fumes during aluminum arc welding causes a severe pneumoconiosis characterized by diffuse pulmonary accumulation of aluminum metal and a corresponding reduction in lung function. Aluminum fume-induced pneumoconiosis is a rarely reported entity, of which the true incidence is unknown. We report the clinical, radiographic, microscopic, and microanalytic ...
