Pseudomyxoma peritonei associated with colloid carcinoma of the pancreas.
A case of pseudomyxoma peritonei associated with a mucin-rich, "colloid" adenocarcinoma of the pancreas is described. This previously unreported association was characterized by an extremely rapid clinical course, transerosal spread of the neoplastic process, and the consistent presence of intracytoplasmic lumina in all cells, an ultrastructural feature thought to characterize malignant lesions.
