A The mass consisted of two main components: multiple papillary growths and cystic spaces with bright eosinophilic cells within lymphoid tissues (left) and extensively fibrotic tissue with multiple vaguely formed lymphoid follicles (right). (H&E, original magnification Ă—20). B The first component consisted of multiple papillary cystic spaces lined by oncocytic epithelium with diffuse lymphocytic infiltrate with lymphoid follicle in the stroma. (H&E, original magnification Ă—40) (Inset: the cystic lining is bilayer of luminal columnar cells and abluminal cuboidal cells; both cells have granular eosinophilic cytoplasm. (H&E, original magnification Ă—200). C The second component of the mass showed diffuse sclerotic fibrosis with scattered lymphoid follicles exhibiting folliculolysis, and inflammatory infiltrate. (H&E, original magnification Ă—40). D A prominent eosinophilic infiltrate was present within the sclerotic stroma and between the lymphoid follicles, which were admixed with lymphocytes and histiocytes. (H&E, original magnification Ă—100). E The lymphoid follicles showed follicular hyperplasia with mantle zone preservation with proteinaceous deposits and perivascular fibrosis. (H&E, original magnification Ă—200)
