Jung CY, Kwon KY - Tuberc Respir Dis (Seoul) (2012)

Bottom Line: A 60-year-old woman was referred to our hospital with a pulmonary nodule.The protrusions into the left main bronchus were found by accident while performing bronchoscopy during lung cancer evaluation.The bronchial lesions were diagnosed as extranodal MZL.

ABSTRACT
Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type (extranodal MZL) is a distinct subgroup of non-Hodgkin's lymphoma. Pulmonary extranodal MZL is a rare entity and accounts for less than 0.5% of primary pulmonary malignancies. Only a few cases of simultaneous occurrence of lung cancer and pulmonary extranodal MZL have been reported. A 60-year-old woman was referred to our hospital with a pulmonary nodule. She was diagnosed with lung adenocarcinoma by percutaneous needle biopsy. The protrusions into the left main bronchus were found by accident while performing bronchoscopy during lung cancer evaluation. The bronchial lesions were diagnosed as extranodal MZL. Although the patient underwent surgical resection for the lung adenocarcinoma, the pulmonary extranodal MZL was left untreated; it was monitored during follow-up visits. To our knowledge, this is the first report of synchronous lung adenocarcinoma and primary extranodal MZL of the main bronchus.

Figure 2: Fluorine 18-labeled fluorodeoxyglucose-positron emission tomography-computed tomographic scan shows a hypermetabolic nodule in the right upper lobe (SUVmax, 11.2).

Mentions: A chest radiograph showed a nodule in the right upper lung (Figure 1A). A chest computed tomographic (CT) scan showed a peripherally located 2.4×1.8 cm sized solid nodule in the anterior segment of the right upper lobe (Figure 1B). Fluorine 18-labeled fluorodeoxyglucose (FDG)-positron emission tomography-CT scan revealed abnormal FDG uptake in the right upper lobe lung nodule and in the right hilar lymph node (Figure 2). She underwent CT image-guided percutaneous core needle biopsy of the nodule in the right upper lobe. Additionally, a flexible bronchoscopic examination was performed to identify the endobronchial lesion. At bronchoscopy, a few small variable-sized protrusions were observed in the proximal left main bronchus and a biopsy was performed (Figure 3).
