[Pulmonary MALT lymphoma and paraneoplastic syndromes].

BACKGROUND

Primary pulmonary lymphoma is a rare disease; diagnosis is often delayed because of atypical clinical presentation and slow progression.

METHODS

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.

CONCLUSIONS

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.
