[Invagination caused by angiolipoma of the small intestine--a rare cause of occult gastrointestinal hemorrhage].

We present the case of a 71-year-old woman who was hospitalized because of a severe hip contusion. She had no symptoms or clinical signs of abdominal disease. Routine blood testing showed anemia, presumably owing to occult bleeding. Ultrasonographic abdominal screening revealed ileo-ileal intussusception with a central hyperechoic tumor suggestive of a lipoma as lead point. This diagnosis was confirmed at surgery, where a small bowel resection was performed. Histologic examination disclosed a benign angiolipoma of the ileum with a superficial shallow ulceration which obviously was the source of the occult blood loss. Diagnostic and therapeutic procedures and a literature review are discussed.

Angiosarcoma of the heart causing cardiac rupture: a rare cause of hemopericardium.

Cardiac rupture as a complication of primary cardiac tumors has rarely been reported in the literature. The diagnosis is difficult to establish preoperatively, but echocardiography may provide the best assessment of cardiac damage. We found a loculated pericardial effusion on two-dimensional echocardiography, a finding that has been documented in two of the previous four case reports. A case of right atrial rupture is reported with review of other cases from the literature.

Meiosis and sex chromosome aneuploidy: how meiotic errors cause aneuploidy; how aneuploidy causes meiotic errors.

As a group, sex chromosome aneuploidies - the 47,XXY, 47,XYY, 47,XXX and 45,X conditions - constitute the most common class of chromosome abnormality in human live-births. Considerable attention has been given to the somatic abnormalities associated with these conditions, but less is known about their meiotic phenotypes; that is, how does sex chromosome imbalance influence the meiotic process. This has become more important with the advent of assisted reproductive technologies, because individuals previously thought to be infertile can now become biological parents. Indeed, there are several recent reports of successful pregnancies involving 47,XXY fathers, and suggestions that cryopreservation of ovarian tissue might impart fertility to at least some Turner syndrome individuals. Thus, the possible consequences of sex chromosome aneuploidy on meiotic chromosome segregation need to be explored.
