  • Abstract
  • Look Inside

Immunofluorescent study, using formalin-fixed, paraffin-embedded tissues and highly specific anti-bodies, revealed that immunoglobulin chains (γ,κ and λ) were simultaneously present in single tumor cells of a primary malignant lymphoma of the brain. Such cells were estimated to be 10 to 30% of the total cell population. Cytologic analysis of the individual immunoglobulin-positive and negative cells by means of additional hematoxylin-eosin stain to the same section suggested that these immunoglobulin chains were not of exogenous origin but were synthesized at the site and that the tumor, therefore, belonged to B cell system.
