Pulmonary tumour thrombotic microangiopathy (PTTM) resulting in fatal pulmonary hypertension is a rare complication of malignancy. Patients with PTTM generally suffer rapid deterioration of hypoxaemia, and a diagnosis is often only made at autopsy. We report a case of extramammary Paget's disease associated with PTTM. An ante-mortem diagnosis was made based on cytology of blood aspirated from a pulmonary artery catheter in a wedged position. Together with a review of the literature, this case highlights the potential diagnostic value of blood cytology in patients with cancer with rapidly progressing pulmonary hypertension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
