title: [Actinomycosis of the caecum simulating carcinoma in a patient with a long-term intrauterine device].
abstract: BACKGROUND
  Actinomycosis of the caecum is a rare, but most frequently an abdominally localized disease. It often simulates inflammatory malignancy, rarely a periappendicular abscess or Chron's disease and is only exceptionally the cause of intestinal obstruction or bleeding.
  
  
  METHODS
  The authors present a 35-year-old woman with an intrauterine device which remained inserted for over three years, causing the development of pain, fever, vaginal secretion and bleeding that continued even after the device was removed. Ultrasonography showed a tumorous mass of irregular form located close to the uterus, which after a few months developed into a colliquation filled with pus requiring incision. Bacteriological examination failed to show actinomycosis. Due to the tumorous lesions involving the terminal ileum, appendix, caecum, ascending colon and omentum, a right hemicolectomy was performed. Based on histolopathological findings of the resected sample the diagnosis of actinomycosis was made. Therefore, after surgery the patient began treatment with antibiotics resulting in full recovery.
  
  
  CONCLUSIONS
  Although rare, actinomycosis of the caecum should be taken into consideration in the differential diagnosis of tumorous lesions of the caecoascending part of the colon, particularly if the tumour is associated with inflammation.
