A 60-YEAR-OLD man had a 1-week history of headache and right-sided motor weakness. On physical examination, firm, immobile nodules were noted over the frontal scalp, face, jaw, shoulders, hands, chest, and abdomen. Some of the nodules were associated with calcified scars (Figure 1). Neurologically, the patient had moderate right hemiparesis. He had no history of recent head trauma. A computed tomographic scan showed a subdural hematoma with massive brain shift and a high-density area in the forehead, as well as subcutaneous calcifications in the face (Figure 2). Radiography of the chest demonstrated widespread and multiple small spotted radio-opaque deposits. Results of laboratory examinations, including endocrine and metabolic tests, were within the normal ranges.
