Schamberg's Disease

Anyone ever heard of this?
Ralph developed this rash (looks like ring worm) went to Demertologist, had a biopsy and this is what they found.
Every thing I am reading says it is nothing to worry about. They told me it could take as long as a year to disapear.
Oh well,
Ralph just wants to keep me on my toes!.
Even the Nephro was taken back.
Another day in the like of the Colongione’s
Life is Great!

Huh, never heard of this before, but it looks harmless. You’ve probably already seen this, but here’s what the Mayo Clinic says: http://www.mayoclinic.com/health/schambergs-disease/AN01104.
