In a case of infantile mucolipidosis type II (I-cell disease), storage was identified at autopsy in serous-type secretory cells in exocrine pancreas, in the tracheal and sublingual salivary glands and in the chief (zymogenic) cells of the gastric oxyntic glands, suggesting a systemic involvement of this type of secretory cells. The content of specific secretory granules was inversely proportional to the intensity of the storage process. The mucus-producing cells were not affected. The serous glandular system is a novel storage site in I-cell disease. Review of archival material in three further cases confirmed the findings.

D007223 Infant A child between 1 and 23 months of age. Infants
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D009081 Mucolipidoses A group of inherited metabolic diseases characterized by the accumulation of excessive amounts of acid mucopolysaccharides, sphingolipids, and/or glycolipids in visceral and mesenchymal cells. Abnormal amounts of sphingolipids or glycolipids are present in neural tissue. INTELLECTUAL DISABILITY and skeletal changes, most notably dysostosis multiplex, occur frequently.

D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
