Cardiac hemangioma of the left atrial appendag: a case report and discussion.

Cardiac hemangioma is an extremely rare, benign vascular tumor of the heart. In contrast to myxoma, hemangioma rarely involves left atrial tissue in adults and little information about the tumor is available. We encountered a 65-year-old woman with a left atrial hemangioma arising in the appendage and growing like an extracardiac mass. The tumor was removed from the left atrium with all the left appendage under cardiopulmonary bypass. Histopathological examination revealed that it was a cavernous-type hemangioma. Among the five described cases, this case was the only one in which the tumor arose from the appendage and grew into the pericardial cavity with resultant paroxystic atrial fibrillation.

Yersinia enterocolitica intestinal infection with ileum perforation: report of a clinical observation.

Yersinia enterocolitica infection is responsible in human beings for ileocolitis appearing with abdominal pain, diarrhoea and fever. This kind of disease usually heals spontaneously with no remarkable complication. Intestinal perforation is a rare complication of the disease. To date only eleven cases of surgical complications arising from abscess and intestinal perforation due to Yersinia enterocolitica have been reported in literature. In our clinical case the patient, who had previously undergone appendicectomy, required urgent surgery for pelvi-peritonitis due to intestinal perforation on necrotic-ulcerative ileitis with adenomesenteritis from Yersinia enterocolitica. The surgical treatment combined with intestinal resection and targeted antibiotic therapy have proved to be effective.
