Unnecessary laparotomy for abdominal pain and fever due to clofazimine

Dear Salvatore
I wonder if the patient was taking clofazimine.  If so, the red coloration might be due to clofazimine.  Clofazimine can cause abdominal pain, sometimes mimicking an acute abdomen.  The pain is thought to be due to an inflammatory reaction to crystals of the drug deposited in the small bowel mucosa and mesenteric lymph nodes.  For this reason the high starting dose (300 mg) of clofazimine that is used to control ENL (Type 2) reactions, should be reduced after 2 or 3 weeks.  References go back a long way, but here are some recent ones.

I made the same mistake in 1979
