Light microscopic examination of recurrent tumor. Low-power magnification (×50) show that recurrent tumor cells formed follicular colonization in the germinal centers throughout the tumor (A). High-power magnification (×630) show centrocyte-like cells and plasmacytoid differentiation in the recurrent MALT lymphoma. Plasmacytoid differentiation was more prevalent in the recurrent tumor than in the primary tumor (B).
