Pulmonary tumour thrombotic microangiopathy (PTTM) is a rare complication of cancer characterized by widespread tumour cell emboli in small arteries and arterioles of the lung and often accompanied by microthrombi. We report a case of PTTM in a young Chinese woman that presented as gastric signet ring cell carcinoma. Although rare, PTTM should be considered in cancer patients with a rapidly progressing dyspnoea, chest computed tomography (CT) scan suggestive of pulmonary hypertension and diffuse pulmonary interstitial infiltration.
