The combination of alopecia and pustules is most consistent with tinea barbae.
#4. What is the diagnosis?
The electrocardiogram shows two QRS complexes with different axes. The patient has a cardiac allograft in addition to his native heart.
#5. What is the diagnosis?
The finding of bilateral multiple cavitary lesions with air fluid levels is most consistent with multiple pulmonary bacterial abscesses.
#6. This patient presented with loss of vision. What is the diagnosis?
Diffuse retinal whitening, constriction of the arteriole and venule with segmentation and a cherry red spot in the macula are most consistent with central retinal artery occlusion.

#9. This 84-cm tall 40-year-old man underwent whole-body dual-energy x-ray absorptiometry. What is the diagnosis?
The image demonstrates scoliosis, a radial orthopedic rod, and fragmentation of the epiphyseal growth plates consistent with osteogenesis imperfecta.
