A large, highly ossified craniopharyngioma was diagnosed and surgically treated in a 2-year-old girl. About 20 teeth were macroscopically identified in the operative specimen, some of them totally developed, complete with crown and root. Pathological study established the diagnosis of craniopharyngioma with formation of teeth. Only five cases have been reported previously, and only one patient survived the operation. The patient is alive 3 years after surgical treatment. Radiotherapy was not used.

A morphometric study of the distal esophageal mucosa (within 5 cm above the gastroesophageal junction) has been carried out in a group of 11 cirrhotic patients undergoing esophageal transection with SPTU gun for variceal bleeding. The relative thickness of the papillae (62.2 +/- 3.9%) and basal zone (11.8 +/- 1.9%) were within normal limits. Polymorphonuclear infiltrates were not found either in the lamina propria or in the epithelium. The absence of histopathologic changes in the esophageal mucosa from patients with liver cirrhosis and bleeding esophageal varices confirms the hypothesis that gastroesophageal reflux does not play a pathogenic role in the development of variceal bleeding.

Five cases of malignant fibrous histiocytoma located in the retroperitoneum are reported. Paraneoplastic syndrome, abdominal mass, tendency to local recurrence, laborious therapy and poor prognosis are the clinical characteristics of this tumor. Accuracy of actual diagnosis is evaluated and pathological features are analyzed.
