Cardiac myxoma are a diagnostic dilemma, simulating a variety of cardiac and non cardiac diseases. Echocardiography is a powerful technique for diagnosing primary tumors of the heart.

[Solitary ulcer syndrome: anatomo-clinical aspects].

The clinical, radiological, endoscopic and histological aspects of a case of Isolated Ulcer Syndrome (IUS) of the rectum are examined.

The case presented serves to highlight the possibility of confusing this ulcer with other inflammatory colorectal conditions if only the clinical, radiological and endoscopic pictures are taken into consideration.
