Multiple lymphomatous polyposis of the gastrointestinal tract
摘要:
A detailed histopathologic and immunohistochemical study has been carried out on 3 rare cases of multiple lymphomatous polyposis (MLP) of the gastrointestinal tract. The case was recognized as mucosa-associated lymphoid tissue (MALT) lymphoma, that originated from the marginal zone cell (MZC), which disseminated to form MLP. It was because the lymphoepithelial lesion (LEL) was distinctively exhibited and the medium-size cell with nucleus showing marked cleavation, positive dot for LN1 of paranuclear in tumor cells was found immunohistochemically. The other two cases were identified as mantle zone lymphomas (MCL) of multicentric origin, since the main component cells within the vague nodules were small and round nucleus with slight cleavation, negative for LN1 and positive for LN2, and no LEL was found.
