Type 1 Pulmonary Hypertension and Silicosis in a Bluestone Cutter: A Case Report on Raising Awareness

This case report describes a patient who developed pneumoconiosis in the form of silicosis and group 1 pulmonary hypertension (PH) due to his unprotected work as a bluestone cutter. Bluestone is a type of sandstone used in outdoor construction commonly in the North-east region of the US. In the literature and to our knowledge, blue stone mining has not been viewed as a risk factor for pneumoconiosis. This case report aims to increase awareness about this occupational hazard. Additionally, it is known that chronic silicosis with massive pulmonary fibrosis can lead to hypoxemia and group 3 pulmonary hypertension. This case, however, demonstrates a possibility of silica dust exposure leading to group 1 pulmonary arterial hypertension.
