[A case of gastric hemangiopericytoma].

The authors report a case of gastric hemangiopericytoma. This tumor, histogenetically derived from pericytes, has been detected in any tissue or structure. According to the review of the literature, the hemangiopericytoma of the stomach occurred very uncommonly, being published only 29 cases. Diagnosis is based on histological and immunohistochemical techniques. Surgery is the main therapy but the impredictable biological behaviour require different strategies.

[Prospective research on fetal cholelithiasis: incidence, predisposing conditions, echographic diagnosis, and clinical features].

The Authors report a prospective study on fetal cholelithiasis, analyzing its differences with the more widely known cholelithiasis of paediatric age. The study shows that the number of cases diagnosed by ultrasonography is higher than expected (0.39%, 3 cases on 764 pregnancies). The Authors could find no correlation between fetal cholelithiasis and any maternal, obstetrical and fetal factor. They have focused attention on sonographic imaging showing clinical-instrumental correlation between echogenic material, clinical features and their evolution. The study confirms that the most common evolution results in spontaneous resolution of fetal endocholecystic pathological images. Finally, wide review of the international literature is reported on the rare, but possible clinical manifestations and their complications.
