The clinical manifestations of non-Hodgkin's lymphomas (NHL) are unspecific and may vary with their location, growth rate or organs involved. Chylothorax consists of an accumulation of chyle in pleural space. Lymphoproliferative diseases represent the main non-traumatic aetiology. The authors report the case of an 81-year-old woman admitted with right pleural effusion and lower limbs oedema, initially interpreted as decompensated heart failure. The thoracocentesis revealed a chylothorax and the aetiological study exposed a mantle cell lymphoma. The authors aim to alert to a less frequent presentation of NHL and remind that a low suspicion may delay the diagnosis.
