Figure 4: (a) Shows effaced architecture of lymph node. (b) shows numerous epithelioid cell granulomas with langhans giant cells and interspersed lymphocytes replacing the entire lymph node, no evidence of caseous necrosis. (c) (TBLB) shows pseudostratified columnar epithelium with lymphoplasmacytic infiltration. (d) shows numerous compact non caseating granulomas composed of epithelioid cells and langhans giant cells, with no peripheral cuffing of lymphocytes
