[Malignant hemangiopericytoma with breast metastasis].

The authors report on a rare case of malignant hemangiopericytoma. A 56-year old female patient had developed a painless node on her left gluteal region 20 years ago. Years later, the resistance became tender and was subsequently surgically removed. On histology, the lesion was identified as malignant hemangiopericytoma. After a symptom-free period of 8 years distant pulmonary metastases arose, which were removed by surgery again. Shortly afterwards the patient manifested with further metastasis involving the lung again, as well as the abdomen, the skin and the breast, leading to the patient's death 2 years later. The authors review the literature, clinical course, diagnostic possibilities, prognosis and therapeutic options of malignant hemangiopericytomas. Special attention is drawn to the unexceptionally long clinical course at this particular malignancy, as well as to the late occurrence of metastases and their unusual breast localisation.

Placental villous edema: a possible cause of antenatal hypoxia.

This study was undertaken to determine the relationship between the placental villous edema and the characteristic sequelae of antenatal hypoxia, i.e. the need for resuscitation at birth and low pH values in umbilical arterial blood. Placental villous edema was recognized by finding of open spaces within the cytoplasm of intervillous cells and in the interstitium of the villi. The percentage of edematous villi was significantly higher in the group of newborns requiring resuscitation. The severity of the edema had a positive correlation with the need for resuscitation at birth and with the arterial blood pH values in the umbilical cord. Placenta praevia and maternal toxicosis were associated with high percentage of edematous villi. It is suggested that edema fluid interposed a barrier to gas exchange between mother and fetus. The capillaries were blocked by compression leading to reduction in blood flow through the villi. These abnormalities, if widespread, may reduce gas exchange. It is suggested that hypoxia could partly be prevented by preventing the development of placental villous edema.

Intrauterine growth of infants with chorioamnionitis.

The relationship between chorioamnionitis and fetal growth was examined by analysing the data of 299 infants with chorioamnionitis and the data of 296 infants with normal placentas. Six parameters were used for estimation of fetal growth: birth weight, length, head circumference, ponderal index, the ratio of length to head circumference and gestational age. Chorioamnionitis was identified, when at least 10 neutrophils per microscopic high-power field were present in the plate of placenta. There was no significant difference between the two groups at full term infants. The comparison could not be made under 37 weeks of gestation. It was concluded that chorioamnionitis probably did not impair particularly the fetal growth.
