Abstract
We present a rare case of primary low-grade B-cell lymphoma of the thy mus. The tumor showed the typical features of a MALT (mucosa-associate d lymphoid tissue) lymphoma with epithelium-lined thymic cyst. Histolo gically, there were sheets of centrocyte-like (CCL) cells intermingled with small lymphocytes and plasma cells. CCL cells invaded the epithe lium of the cyst and residual Hassall's corpuscles, forming characteri stic lymphoepithelial lesions. Immunohistochemically, the tumor cells revealed positive immunoreaction for CD20 and monotypic cytoplasmic re striction of kappa light chain.
