Kryptogenne wieloogniskowe wrzodziejące zwężające zapalenie jelit

A rare intestinal disease characterized by chronic or relapsing subileus or ileus resulting from multiple unexplained fibrous structures and multiple shallow (i. e. limited to the mucosa or submucosa) ulcerations of the small intestine (mainly the ileum), in the absence of signs of a systemic inflammatory reaction. Patients may present with chronic iron-deficiency anemia due to chronic intestinal blood loss, chronic recurrent abdominal pain, fatigue, edema, or growth retardation. Extraintestinal manifestations such as Sicca syndrome, polyarthralgia, or Raynaud's phenomenon may also be observed.
