Pulmonary MALT lymphoma and paraneoplastic syndromes

Introduction. - Primary pulmonary lymphoma is a rare disease; diagnosis is often delayed because of atypical clinical presentation and stow progression. Observation. - A 42-year-old woman consulted because of haemoptysis. Chest CT-scan showed multiple nodular calcified masses. A lung biopsy led to the diagnosis of pulmonary amyloidosis with pulmonary MALT lymphoma (mucosa-associated lymphoid tissue). The patient developed two paraneoplastic syndromes: a hypertrophic osteoarthropathy and mucinosis. Conclusion. - Multiple nodular amyloidosis can be a mode of presentation for pulmonary lymphoma. Paraneoplastic syndromes must be systematically considered and can help in early diagnosis of the disease and its relapse. (C) 2016 SPLF. Published by Elsevier Masson SAS. All rights reserved.
