[Recurrent lower gastro-intestinal bleeding in a 38-year-old patient].
METHODS
A 38-year-old patient with a history of recurrent gastrointestinal bleeding for more than 15 years was transferred for the treatment of a new onset of hematochezia and anemia. His general condition was clearly reduced.


RESULTS
Laboratory results showed a distinct microcytic hypochromic anemia; ferrum, ferritin, albumin, and protein were also diminished. Colonoscopy and transrectal ultrasound uncovered large hemangiomatous structures in the rectum. Digital substraction angiography of the bilateral internal iliac artery, superior and inferior mesenteric arteries including its branches showed a perirectal polypoid tumour with a discrete angiomatous structural shadow in the capillary phase. MRI of the pelvis revealed angiomatous blood vessels in the whole pararectal space and to a minor extension in the gluteal muscles.


METHODS
The diagnosis of cavernous hemangioma of the rectum was made and a distal mesorectal resection of the rectum including a coloanal anastomosis and double-running ileostomy was performed. 3 months later the ileostomy was reversed. There was no further bleeding and the rectal continence was normal.


CONCLUSIONS
In case of unclear recurrent lower gastrointestinal bleeding, with onset in the early childhood and impressive rectal varices, one has to think about the rare diagnosis of cavernous hemangioma.
