AN AUTOPSY CASE

A diagnosis of the heritable disorder Sipples syndrome was made in a Japanese male aged 28 years. The coexistence of bilateral pheochromocytomas, bilateral medullary thyroid carcinomas and secondary hyperplasia of parathyroid was confirmed at the time of autopsy. Pancreatic islets were hyperplastic with marked proliferation of A and D cells. Transition of the ductal cell to the islet, i.e. ‘nesidioblatosis’ was observed. There was no proliferation of B cells, but a retention of B cell granules, a manifestation of suppressed secretion of insulin attributed to the overproduction of catecholamines was evident. In the stomach, numerous petechial hemorrhages and proliferation of gastrin cells were found. The pathogenesis of changes in the pancreatic islets and stomach is discussed from the viewpoint of hormonal disorders induced by pheochromocytoma and medullary thyroid carcinoma such as are found in Sipples syndrome.

Clinical Evaluation of Brushing Cytology and Biopsy of the Pancreatic Duct in Patients with Mucin Producing Tumor of the Pancreas

Abstract: A cytological study of pure pancreatic juice obtained endoscopically after brushing the lesion of the pancreatic duct urns performed in 10 patients with mucin producing tumors of the pancreas. In 6 of these 10 patients, biopsies from the lesion in the pancreatic duct were also carried out endoscopically.
