“…From the time when there were no findings at all, we were able to follow up the course of the disease over a period of 4 years. The change in size of EML appeared to be variable from a report where the tumour size did not change over 16 years 34 to another case that caused significant stenosis of the left mainstem bronchus 10 . As for our case, the tumour size increased during subsequent annual follow ups that indicated a need for aggressive treatment measure.…”

“…We herein report a case of EML that was diagnosed through a chest computed tomography (CT) during an annual health checkup which was successfully treated with radiotherapy. To the best of our knowledge, only 48 cases of EML have been reported in the literature 1–38 . To date, a comprehensive review of this rare condition is not available.…”

A 60‐year‐old man was noted to have an elevated lesion in the right mainstem bronchus on chest computed tomography (CT) during his annual medical checkup 3 years previously. The lesion had gradually increased in size. FDG‐PET showed no accumulation. Bronchoscopy revealed 5 nodular smooth surface protrusions on the ventral surface of the right mainstem bronchus, with the largest lesion that measured 5 mm in diameter. Biopsy showed diffuse infiltration of small lymphocytes, positive for CD20 and subsequently diagnosed with mucosa‐associated lymphoid tissue (MALT) lymphoma. The lesions disappeared on chest CT after radiotherapy, and no recurrence has been observed after 5 years. We reviewed 48 cases of endobronchial MALT lymphoma in the literature and provided a comprehensive review of the literature to date including our case.

ObjectiveTo investigate CT and 18F-flurodeoxyglucose (18F-FDG) positron-emission tomography/CT findings of primary endobronchial marginal zone B-cell lymphoma of the bronchus-associated lymphoid tissue (BALT).Materials and MethodsFrom June 2006 through April 2012, seven patients (six female, one male; age range, 21-61 years; mean age, 49 years) were examined who were pathologically diagnosed with the primary endobronchial marginal zone B-cell lymphoma of BALT. We evaluated the locations and characteristics of the lesions on CT and 18F-FDG-PET/CT scans. The lesions were classified into the following three patterns: 1) solitary intraluminal nodule; 2) several tiny nodular protrusions; and 3) diffuse wall thickening.ResultsA solitary intraluminal nodule was observed in four patients (57.1%), several tiny nodular protrusion in two patients (28.6%), and diffuse wall thickening in one patient (14.3%). The lesions were categorized into 3 major locations: confined to the trachea (n = 3), confined to the lobar bronchus (n = 2), and diffuse involvement of the trachea and both main bronchi (n = 2). All lesions demonstrated homogeneous iso-attenuation as compared with muscle on pre- and post-enhancement scans. Secondary findings in the lungs (n = 3; 42.9%) included postobstructive lobar atelectasis (n = 1), air trapping (n = 1), and pneumonia (n = 1). On 18F-FDG-PET/CT (n = 5), 4 lesions showed homogeneous uptake with maximum standardized uptake values (mSUV), ranging 2.3-5.7 (mean mSUV: 3.3). One lesion showed little FDG uptake.ConclusionPrimary endobronchial marginal zone B-cell lymphoma of the BALT manifests as three distinct patterns on CT, with the solitary intraluminal nodule presenting as the main pattern. Most lesions demonstrate homogeneous but weak FDG uptake on 18F-FDG-PET/CT.

“…A previous study reported that endobronchial MALT lymphoma was seen in only 1 (1.3%) of 75 cases of nongastrointestinal MALT lymphoma [5]. Including the present case, 28 cases [[6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22]] in a PubMed search and 7 cases in Japanese journals of primary endobrochial MALT lymphoma have been reported.…”

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of pulmonary origin is a relatively rare disease. In particular, reports of MALT lymphoma occurring and localized in the trachea or bronchus have been limited. Pulmonary MALT lymphoma has been reported to demonstrate spontaneous regression, whereas there is only one reported case of spontaneous regression of primary endobronchial MALT lymphoma. We herein report the case of a 70-year-old man with primary endobronchial MALT lymphoma who showed spontaneous regression with an interest of endobronchial findings.
