Patient case (clinical description): A 20-year-old man comes to the clinic for his routine checkup. The patient wears glasses for myopia and takes no medications.  Vital signs are normal.  On physical examination, the patient is tall with long upper extremities and fingers.  The face appears narrow with down-slanted palpebral fissures, flattened malar bones, and a small jaw.  The lungs are clear on auscultation.  The abdomen is soft with no organomegaly. The patient is diagnosed with Marfan syndrome, and he is cooperative with his medical appointments. He is working as driver.

Patient's own account: I'm a 20-year-old guy, working as a driver and I went to the clinic for my routine checkup. I have myopia, so I wear glasses and I don't take any other medications. My vitals were normal. I also did a physical exam, and I was told that I have long legs, arms, and fingers. They also told me that my face is quite narrow, with down-slanted eyes and a small jaw. My lungs were fine and my tummy too. I have been diagnosed with Marfan syndrome and I haven't been skipping any medical appointments since.
