ABSTRACT
A 66-year-old woman presented with abdominal pain and weight loss. Ultrasonography and computed tomography demonstrated a cystic lesion of the pancreas. After surgical resection, the patient's symptoms disappeared. Microscopic examination of the cyst lining showed mature, keratinizing squamous epithelium, surrounded by lymphoid tissue. Only three cases of this type of lesion, called "lymphoepithelial cyst", have been described previously. Histogenesis of this particular type of cyst is not well know, but can be histologically differentiated from other pancreatic cysts.

Clinical and pathological findings in a forty-eight-year-old woman with malignant mesenchymatous hamartoma of the liver (embryonic sarcoma) are reported. Special emphasis is put on the monomorphic leiomyosarcomatous aspect of the peritoneal metastases, and on the presence of pseudo-tumorous foci abounding in plasmocytes and centered by recent phlebitis.

Two newborn infants who suffered severe intra-uterine anoxia a few weeks before birth are described. Both died shortly after being born spontaneously and slightly prematurely. In one case the mother had attempted suicide by inhaling butane. The infant's kidneys were hypoplastic and resembled those seen in renal dysplasia, and the brain showed a severe encephalomalacia which would probably have developed into hydranencephaly. The other case was a twin who survived the intra-uterine death of her co-twin: she had hypoplastic kidneys similar to those in the first case, and a hypoplastic spleen. (The brain was not examined.) It is thought that intra-uterine anoxia may produce lesions in fetal organs which appear at birth as congenital developmental malformations. This mechanism is thought to account in particular for some cases of renal dysplasia and for hydranencephaly.

We found at postmortem examination the association of bilateral renal agenesis and of apparently complete Di George syndrome in an infant whose mother was diabetic. Vertebral abnormalities and hallux duplication were present as well. There is a correlation between maternal diabetes and the bilateral renal agenesis-caudal dysplasia complex on one hand, and maternal diabetes and cardiac malformations on the other hand. Moreover, it has been suggested that the absence of thymus and parathyroids in Di George syndrome is causally linked to the cardiac malformation. Therefore we suggest that the association in our case is not coincidental; both sets of malformations may be due to the maternal diabetes.
