What is mastocytic enterocolitis?

Mastocytic enterocolitis is a term describing the condition of chronic, intractable diarrhea in individuals with normal colon or duodenum biopsy results, but with an increased number of mast cells in the colonic mucosa (the innermost layer of the colon).[1] The increase in mast cells is not associated with systemic or cutaneous mastocytosis.[2] It is unclear whether the accumulation of mast cells is a response to, or cause of, the mucosal inflammation that causes the symptoms of the condition.[1] Most individuals with this condition respond well to drugs affecting mast cell function.[2]

What are the signs and symptoms of mastocytic enterocolitis?

According to the medical literature, signs and symptoms of mastocytic enterocolitis primarily include chronic, intractable diarrhea and abdominal pain. Other symptoms that have occasionally been reported include constipation, nausea, and/or vomiting.[2]

Although other signs and symptoms appear to have been reported by individuals on various online forums and support Web sites, we were unable to locate additional information about symptoms of the condition in the available medical literature. At this time, literature about mastocytic enterocolitis is scarce.
