Case 1

34 y/o male on chemo for relapsed AML following a bone marrow transplant is transported to your office. 

He has dark spots on neck, cheek, clavicle.  You suspect zoster, but on reviewing the chart see that he has been being treated with IV acyclovir for the last 5 days, before the rash started.

 

Where do you need to look next? 

His mouth.  His mouth shows mucormycosis fungus growing in his sinus cavity.

 

What do you need to do next?

  • Start IV solumedrol
  • Start IV Vanco and Zosyn
  • Get an ENT Consult

  • Hold the Chemotherapy

Answer: Get an ENT Consult

Which anti-body is likely to be positive?

  • Anti-ssDNA
  • Anti-SCL70
