摘要

A 75-year-old male presented to the emergency department with severe chest pain. The patient had never smoked and had a long-standing skin disorder. Physical examination revealed multiple small skin-coloured papules on his face, chest and back.A CT angiogram was performed, which excluded aortic dissection and pulmonary embolus.However, incidental pulmonary findings were found (Figure 1).Based on these images, what is your differential diagnosis?What is your best diagnosis given the clinical history and physical exam findings?Given this diagnosis, what other organ might be abnormal?
