Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare but fatal cancer-related disease. Owing to its non-specific findings, aggressive course, and lack of established treatment guidelines, only a few cases of antemortem diagnosis in long-term survivors have been reported. We aimed to report a case of uterine cervical cancer induced PTTM that was suspected based on pulmonary hypertension and successfully treated using combination chemotherapy despite of delayed diagnose. It is important to be aware that PTTM should be suspected when respiratory failure occurs in patients with unexplained pulmonary hypertension. Multidisciplinary treatments including molecular targeted therapies might be effective treatment options.
肺肿瘤血栓性微血管病(PTTM)是一种罕见但致命的癌症相关疾病。由于其表现不具特异性、病程进展迅速且缺乏既定的治疗指南,仅有少数长期存活者生前诊断的病例报道。我们旨在报告一例由子宫颈癌诱发的PTTM,该病例基于肺动脉高压被怀疑,尽管诊断延迟,但通过联合化疗成功治愈。重要的是要意识到,当不明原因肺动脉高压患者出现呼吸衰竭时应怀疑PTTM。包括分子靶向治疗在内的多学科治疗可能是有效的治疗选择。
