A case report of unusual cavity presentation of pulmonary extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue.

RATIONALE

The common CT scan findings of pulmonary MZBL of MALT type include airspace consolidation, nodules and ground-glass opacity. But, to our knowledge, the present case is the first report of a cavity presentation of pulmonary MZBL of MALT type.

PATIENT CONCERNS

The patient gives his consent and authorizes the photographs featuring his likeness to be published.

DIAGNOSES

This patient was diagnosed as pulmonary MZBL of MALT type by pathology, immunohistochemistry, and gene rearrangement.

INTERVENTIONS

The patient was treated with CHOP (cyclophosphamide, adriamycin, vincristine and prednisone) chemotherapy for twice and antibiotics.

OUTCOMES

He is being followed up for one year, with slight progress in pulmonary MZBL of MALT.

LESSONS

This case highlights the need to be suspicious of MZBL of MALT type, when a radiographic image shows cavity lesion. We should consider whether the diagnosis is correct, when the patient's treatment is not effective.
