title: A human tubular array plasma cell.
abstract: A human plasma cell is described which is distinct with both the light and electron microscope. With indirect immunofluorescence its cytoplasm is immunoglobulin-associated and the ultrastructure is characterized by tubular arrays of endoplasmic reticulum similar to those described in a number of diseases. Hypotheses regarding these tubular structures are reviewed.
