Pulmonary tumour thrombotic microangiopathy: unclassifiable pulmonary hypertension?

Pulmonary hypertension (PH) is defined as a mean pulmonary artery pressure ⩾25 mmHg, and can be associated with multiple conditions. The diagnostic strategy and treatment of PH is heavily reliant on accurately classifying patients [1]. We recently identified two patients presenting with rapidly fatal PH of unknown aetiology, who were subsequently diagnosed at post mortem with pulmonary tumour t...

A case of pulmonary tumour thrombotic microangiopathy.

Pulmonary tumour thrombotic microangiopathy (PTTM) is a rapidly progressive pulmonary disease that is a fatal complication of malignancy. It manifests clinically as subacute respiratory failure with pulmonary hypertension, progressive right sided heart failure, and sudden death. We describe here a case of PTTM associated with occult metastatic signet ring cell carcinoma of the stomach. Although...

Pulmonary Tumor Thrombotic Microangiopathy

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare clinical entity where tumor cell embolisms in pulmonary circulation induce thrombotic microangiopathy (TMA), respiratory failure, and subacute cor pulmonale. We describe 3 cases of PTTM that presented as the initial manifestation of metastatic gastric adenocarcinoma with TMA and pulmonary infiltrates. All 3 cases had similar clinical a...
