From: Presence of a mouse mammary tumour virus-like in feline lymphomas: a preliminary study
Patterns of the nodal and cutaneous feline lymphomas collected. A, B T-cell nodal lymphoma: A Nodal architecture of lymph node effaced by an expanding, diffuse proliferation of intermediate-sized lymphocytes (H-E stain, Ob. 20×); B Neoplastic lymphoid cells positively stained by anti-CD3 antibody (IHC, Ob. 40×). Insert: Cytoplasmatic staining of CD3-positive lymphocites (IHC). C, D Cutaneous T-cell lymphoma: C Dense, monomorphic, diffuse infiltration of CD3+  lymphocytes in the derma of the skin. Lymphocytes are found within the epithelium (IHC, Ob. 20×); D Strong immunostaining with anti-CD3 antibody (IHC, Ob. 40×). Insert: Cytoplasmatic staining of CD3-positive lymphocytes (IHC)
