Glomiform and fibrillar cytoplasmic inclusions.

Glomiform inclusions, also called tubular arrays in endoplasmic reticulum, are found in the epithelial cells of glandular tissues of a patient with systemic lupus erythematosus, a patient with Reye's syndrome, and a dog. Their three dimensional structure is interpreted as a skein of contorted tubules of endoplasmic reticulum. Fibrillar inclusions found in the pancreatic acinar cells of two patients are believed to represent altered zymogen granules.
