| Popis: | A case of primary conjunctival lymphoma is reported herein. A 47-year-old woman presented with an indolent salmon-coloured tumour of the lower epibulbar conjunctiva. Histologically, we found a lymphoid infiltrate in the epithelium and subepithelium consisting of two components. One component was characterized by centrocytic-like cells and the other by lymphocytic, plasmacytoid and plasma cells. An immunohistological study demonstrated a light chain restricted immunoglobulin expression of the tumour cells as well as some residual polytypic follicles exhibiting reticular dendritic cells. Tumour cell proliferation was associated with a T cell reactive population. A comprehensive investigation (in particular an orbital scan) did not demonstrate any other localization of this lymphoma. Such a lesion raised the question of a possible MALT origin, by analog with MALT-lymphomas of the gastrointestinal tract described by Isaacson and colleagues. |
