T o TIlE EDFrOR: We have recently read an interesting paper by Dorfman ~l.lld Warnke in Human Patholo9 [5:519-550, 1974] reporting the occurrence of proteinaceous precipitate in a few cases of lynq~hadenopathy simulating malignant lymphonaa. T h e authors, in agreement with Rosas-Uribe and coworkers [Cancer, 31:534-5-t2, 1973], emphasize the unknown origin of this material and believe that it has some functional as well as tOl)ographical relationship to plasma cells. In a study on proteinaceous material in I)'nq)homas we obtained some dam with regard to this subject that ma}' therefore be of interest. We found 25 instances of proteinaceous pre-

Semithin sections show a close relationship between plasma cells and proteinaceous material, and electron microscopic investigations confirm the presence of plasma cells in close proximity to dense microgranular material filling the intercellular spaces (Figs. 1, 2). T h e osmiophilic material shows an amorphous background in which scattered collagenlike fibrils are present. Sometimes the collagen-like fibrils are aggregated to form large bundles, which on the sections appear to be parallel to the plasma meml)rane of the plasma cells. Most of the cellular surface is coated with this electron dense ntaterial (the "proteinaceous material" of light microscopy). T h e plasnm cells have a.characteristically abundant rough endoplasmic reticuhnn in their cytoplasm, with flattened cisternae in
