ABSTRACT

A 45-year-old man presented with chronic cough and dyspnea in August 200X-2 after putting white line paint materials, mainly consisting of calcium carbonate, into a drawing assisting unit many times, without use of a face mask. He then used this unit to draw lines on the ground for setting up a car park. He had been followed up in another hospital, but when his dyspnea worsened in January 200X, he was referred to our hospital. A chest computed tomography revealed peripherally dominant ground-glass density in both upper lungs. We performed thoracoscopic lung biopsy of the left lung, and the biopsy specimens showed diffuse calcium deposits and many foreign giant cells in the alveoli. Inductively coupled plasma emission spectroscopy (ICPS-8100, SHIMADZU) analyzed chemical elements of white line materials and specimens of his lung, which had almost the same elements. We diagnosed his lung injury as being caused by inhalation of the white line powder.
