“…Dominancy of CD20-positve cells and low Ki-67-labeling index should be correlated with, but not an absolute criterion of, MALT lymphoma. Overt ML may not show clonality in paraffinsection immunohistochemistry and it is not possible to show restriction of k-or l-immunoglobulin light-chain in all cases of MALT lymphoma even in FCM, due to the frequent presence of interspersed reactive B cells (13). Fortunately, in both of the present cases, significant light-chain predominance was observed by FCM.…”

“…However, at the very least, these CT and MRI findings suggest the possibility of MALT lymphoma. On the other hand, CT and MRI findings for thyroid lymphoma are entirely non-specific, appearing as ill-defined hypodense nodules, with low contrast enhancement (13). Actually, thyroid lymphoma is often identified from pathological findings in a gland resected for an apparently benign disease, and correct preoperative diagnosis is extremely difficult (14).…”

“…Computed tomography (CT) and magnetic resonance imaging (MRI) are complementary to US and provide comprehensive evaluation of the whole head and neck region, encompassing all lymphatic, extra-lymphatic and nodal sites. MALToma is isoattenuating to mildly hyperattenuating [22], with mild to moderate contrast enhancement on CT [23,24] (Figs. 7 and 8c).…”

Marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALToma) arises in extranodal sites in the head and neck. Chronic inflammatory, infectious or autoimmune conditions are implicated in its pathogenesis. Within the head and neck, MALToma is often multifocal and indolent and the imaging appearances may be mistaken for non-malignant disease in the head and neck. The aim of this article is to illustrate the varied radiological and clinical features of MALToma in the head and neck, an awareness of which is needed for timely and correct diagnosis to guide subsequent disease management.

“…Common associated findings are air bronchogram within these lesions, positive angiogram sign on contrast-enhanced CT, and perilesional areas of ground-glass attenuation. 6,7 However, imaging findings of cases involving multiple organs including the lung have not been described in detail. In our patient, multiple organs including the lung were involved at diagnosis, and the primary site was unknown.…”

W e report a case of mucosa-associated lymphoid tissue (MALT) lymphoma involving multiple organs including the lung. A 78-year-old woman presented with a left asymptomatic submandibular mass that had been present for 2 months. Her chest radiograph and computed tomographic (CT) scan revealed multiple micronodules and thickening of bronchovascular bundles, suggestive of lung diseases with lymphangitic spread. Lung histology showed extranodal marginal zone B-cell lymphoma of MALT type, and CT scans and bone marrow aspiration revealed the involvement of the submandibular gland, abdominal lymph nodes, and bone marrow. Treatment of rituximab alone led to a partial response of the tumors. Although MALT lymphomas tend to be localized, multiple-organ MALT lymphoma should be considered in the differential diagnosis of lung diseases with a lymphangitic pattern. DISCUSSIONMALT lymphomas are low-grade lymphomas. They derive from marginal zone B cells that surround the mantle zone and germinal center and are classified as extranodal marginal zone B-cell lymphoma of MALT type, a distinct subgroup of non-Hodgkin's lymphomas. 2 MALT lymphomas tend to remain localized, but involvement of multiple muco-
