Along the same lines as Sue said, there is also an entity called 'carcinoid'. Carcinoid Syndrome or Carcinoid tumors are other interesting topics.

The last website has some interesting info on hypervitaminosis of Vitamin D, which is new info to me. All 3 abstracts concern males, who seldom get the diagnosis of Sjogren's. Billye would probably have the exact stats, but, I belive the incidence is one male to 5 females. Sometimes the gender bias is due to physicians not considering a disease due to old presumptions.
