El carcinoma neuroendocrino de cérvix es un tumor raro y agresivo que se asocia con un mal pronóstico, incluso en estadios precoces. La dificultad en el diagnóstico diferencial puede explicar que este tipo de tumores esté in frarregistrado. El caso que presentamos fue tratado inicialmente como un sarcoma del estroma, confirmando en el estudio definitivo que se trataba de un carcinoma de células pequeñas (AU)

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.

Signet ring cell adenocarcinoma of the bladder is rare. Only 16 cases are recorded in the literature, although two meet the requirements for being considered of urachal origin. We present the third case of signet cell adenocarcinoma of urachal origin.

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.

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.
