چکیده

Pulmonary involvement with multiple myeloma is rare. We report the case of a 61-year-old man with past medical history of chronic respiratory failure with emphysema, and a known multiple myeloma (Durie and Salmon stage III B and t(4;14) translocation). Six months after diagnosis and first line of treatment, he presented acute dyspnea with interstitial lung disease. Computed tomography showed severe bullous emphysema and diffuse, patchy, multifocal infiltrations bilaterally with nodular character, small bilateral pleural effusions, mediastinal lymphadenopathy, and a known lytic lesion of the 12th vertebra. He was treated with piperacillin-tazobactam, amikacin, oseltamivir, and methylprednisolone. Finally, outcome was unfavourable. Postmortem analysis revealed diffuse and nodular infracentimetric infiltration of the lung parenchyma by neoplastic plasma cells. Physicians should be aware that acute respiratory distress syndrome not responding to treatment of common causes could be a manifestation of the disease, even with negative BAL or biopsy and could be promptly treated with salvage therapy.

Acute respiratory distress syndrome due to pulmonary involvement by neoplastic plasma cells in multiple myeloma.

Pulmonary involvement with multiple myeloma occurs infrequently and may be difficult to distinguish from more common primary lung tumours, metastatic disease, or other pleural and parenchymal abnormalities. A patient who developed acute respiratory distress syndrome (ARDS) was subsequently found to have multiple myeloma with involvement of lung parenchyma by neoplastic plasma cells. Only one ot...

Multiple Myeloma Presenting as Respiratory Stridor

Extramedullary plasmacytoma occurs in 18% of patients with multiple myeloma. Laryngeal involvement in multiple myeloma is rare, and only a few cases have been reported. We present a case of a 44-year-old women with multiple myeloma who presented with stridor due to a mass involving the larynx which was initially proven to be plasmacytoma on biopsy. She had evidence of multiple myeloma of IgA la...

Rhabdomyolysis and Acute Respiratory Distress Syndrome Secondary to Multiple Wasp Stings

Background: Wasp stings usually cause local reactions such as itching, urticaria, angioedema and anaphylaxis. Life-threatening complications following multiple wasp stings are relatively rare and unexpected. However, rhabdomyolysis and acute respiratory distress syndrome following wasp stings are possible. Case presentation: A middle-aged male worker was stung by a swarm of wasps all over his b...

Validity of Spo2/Fio2 Ratio in Detection of Acute Lung Injury and Acute Respiratory Distress Syndrome

Introduction:  One ofdiagnostic criteria for Acute Lung Injury and Acute Respiratory Distress Syndrome is  pao2/fio2 (PF) ratio 300 for ALI or 200 for ARDS. This criteria requires invasive arterial sampling. Measurement of Spo2/Fio2 (SF) ratio by pulseoximetry may be a reliable non invasive alternative to the PF ratio.   Methods and Materials: In a cross sectional study we enrolled 105 sample o...
