Histologic findings in OAML. (A) Diffuse infiltration of the conjunctiva by a dense small lymphocytic cell population (hematoxylin and eosin, original magnification ×100). (B) Monocytoid cells arranged in sheets in an orbital mass with plasma cell and a Russell body (; hematoxylin and eosin, original magnification ×1000). (C) Lymphoepithelial lesion in lacrimal gland (hematoxylin and eosin, original magnification ×500). (D) Centrocyte-like cells, plasma cells, and Dutcher body () beneath conjunctival epithelium (hematoxylin and eosin, original magnification ×1000). Images of immunohistochemical staining were acquired using a Nikon Eclipse E400 microscope (Nikon) and a Nikon DS-Li digital camera. Digitized images were processed using Adobe Photoshop 7 image processing and manipulation software (Adobe Systems).
