RESUMO
Isolated caecal perforation following pancreatitis is a rare event. We report a case of severe non-necrotising pancreatitis complicated by caecal perforation that was managed successfully.

The clinical records, preoperative sialograms and histopathological slides of 33 patients who had been operated on for symptoms of obstructive salivary gland disease were reviewed. Twenty patients had had superficial parotidectomy and 13 excision of the submandibular gland. Among those who had required parotidectomy, preoperative sialograms tended to suggest more architectural damage than was actually noted on definitive histopathological examination. Patients whose symptoms had been present for longer had more severe sialographic and histopathological changes. In the submandibular group, there was a closer relation between sialographic and histopathological changes, and a positive correlation between a short history and the severity of histopathological grading. These differences may reflect the different aetiology and course of obstructive disease in the two types of gland.

A primary carcinoid tumor of the mesentery was associated with intestinal obstruction in a 74-year-old man. Increased levels of plasma pancreatic polypeptide were subsequently demonstrated. An autopsy performed four years later showed carcinoid metastatic dissemination and confirmed the primary mesenteric origin of the carcinoid tumor initially resected at surgery.

Seven cases of cystadenoma of the pancreas were examined in detail histologically and histochemically and two variants were identified: a microcyst type lined by glycogen-rich cuboidal epithelium which also secretes some neutral mucins; and macrocystic type lined exclusively by mucus-secreting columnar cells which secrete predominantly sulphated acidic mucins with some neutral mucins. Electron microscopy of two cases of the microcystic variant showed neoplastic cells with an ultrastructure comparable to that of centroacinar cells of the normal exocrine pancreas.
