[Pseudocystic metastases of carcinoma of the uterine cervix mimicking polycystic liver disease]. / Métastases d'allure kystique d'un carcinome du col utérin simulant une polykystose hépatique.

Pseudocystic liver metastases are rare and mainly described in neuroendocrine or ovarian tumors. We report the case of a 46-year-old woman who presented with multiple hepatic metastases mimicking polycystic liver disease. Carcinoma of the uterine cervix had been diagnosed 9 years earlier, and initially treated by radiumtherapy and surgery. Although histological post mortem examination of the pseudocystic liver metastases was not characteristic, they were related to the uterine cervix carcinoma for the following reasons: no other primary tumor was discovered, especially carcinoid or ovarian tumors: immunostains were positive for epithelial cells and negative for the neuroendocrine panel: the cystic cerebellum metastasis had a typical histologic aspect. Uterine cervical carcinoma must thus be included in the list of tumors which may form cystic hepatic metastases.

[Pneumatosis cystoides of the colon: knowing how to recognize it. Apropos of 8 cases]. / Pneumatose kystique du côlon: savoir la reconnaître. A propos de huit observations.

Eight cases of pneumatosis cystoides intestinalis (PCI) affecting the descending colon at first misdiagnosed in seven of them, are reported. The mechanism of cyst formation remains unclear but certain specific endoscopic and X-ray findings should help in differentiating PCI from other intramural tumors, i.e. polyposis. Diagnostic investigations and management approaches are described. No treatment is necessary in most instances because of the benign nature of PCI.
