A cavernous haemangioma of the colon as the cause of rectal bleeding in childhood.

- A 13-year-old girl presented with rectal bleeding, abdominal pain and a palpable mass in the lower right abdomen. The history mentioned a chronic anaemia since she was 2 years old. Further examination did not give any indications for inflammation as etiological factor and showed a thickening of (apparently) the small intestine. A laparotomy was performed, since the age and presentation made a malignant lymphoma a probable diagnosis. The combination of chronic anaemia and rectal bleeding also suggested a benign vascular malformation. A large cavernous haemangioma of the transverse colon was found. This was resected and the patient fully recovered. Although a haemangioma of the colon is rare, it is important to keep this possibility in mind in the case of rectal bleeding in childhood, especially when other causes of rectal bleeding are excluded. Usually haemangiomas show spontaneous regression, but this is rare in intestinal haemangiomas. Surgical resection is the therapy of choice in the case of a solitary haemangioma.
