[Pseudo-aneurysm of mitro-aortic continuity: a rare complication after aortic valve replacement].

Pseudo-aneurysm of the fibrous continuity zone between the aortic and mitral valves, the so-called "mitral-aortic intervalvular fibrosa" is a rare complication of acute infective endocarditis, rarely after an aortic valve replacement. We report the case of a large pseudo-aneurysm occurred in a 70-year-old man, who had a history of surgical aortic valve replacement 3 years before. There were no biological or clinical evidence for infective acute endocarditis.

[Spontaneous remission of congenital leukemia cutis].

Background: Aleukaemic leukaemia--without blasts in the blood or the bone marrow--with isolated cutaneous manifestations has been very rarely reported since only seven patients have been described to date. The prognosis is variable, and the indications for an aggressive treatment such as polychemotherapy are currently unclear. We report a case of spontaneously remitting aleukaemic leukaemia in a newborn child and compare it with other cases in the literature.
