title: Mucolipidosis type II with evidence of a novel storage site.
abstract: 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.
