   “In the one sub-class, we have the Leukaemic Lymphoma, the Typhous Lymphoma, the Hyperplastic Lymphoma (ex. the simple hypertrophied tonsil), Lympho-sarcoma, Scrofulous Glands; and in the other sub-class, Tubercle of man, and Perlsucht or Parresyge, or Morbus Gallicus, the pearl distemper of ruminating animals.”

   “Common immunohistochemical markers of this lymphoma include CD2, CD56, CD3, and T-cell receptors. 7 Typically, the histology of these lymphomas are characterized by monomorphic inflammatory cellular infiltrates, which may be diffuse or show angiocentricity and angiodestruction as well as tissue destruction. 7 Lymphoid markers from the nasal mucosal biopsy from this patient were negative for CD56 and EBER.”
