  • Title: Laryngeal lymphoma derived from mucosa-associated lymphoid tissue.
    Author: Horny HP, Ferlito A, Carbone A.
    Journal: Ann Otol Rhinol Laryngol; 1996 Jul; 105(7):577-83. PubMed ID: 8678438.
    Abstract:
    Extranodal lymphomas account for as many as 40% of non-Hodgkin's lymphomas, and most arise in the gastrointestinal tract, but other mucosal organs may be involved, especially the upper aerodigestive tract. Low-grade B-cell lymphomas arising in the gastrointestinal tract and other mucosae have been found to recapitulate the structure and cytologic features of mucosa-associated lymphoid tissue (MALT). Histologically low-grade MALT lymphomas are characterized by centrocyte-like B-cells with a phenotype similar to that of so-called marginal zone B-cells. Tumors evolving from MALT are generally rare among lymphomas of the upper aerodigestive tract, but a few cases of laryngeal lymphomas derived from MALT have been reported. Primary MALT lymphoma of the larynx should always be considered in tumors with histopathologic features of low-grade B-cell lymphoma, or so-called pseudolymphoma.
