Introduction:
Haemoptysis in pregnancy is frequently assumed to be caused by a pulmonary embolism. However, it can also be an indicator of serious pathology.
Case presentation:
We report the case of a 27-year-old Caucasian woman who presented with haemoptysis in pregnancy that was discovered to be caused by a well-differentiated fetal adenocarcinoma of the lung.
Conclusion:
This case demonstrates the importance of establishing an accurate diagnosis when a pregnant woman presents with haemoptysis and that more serious pathology should be considered if the clinical symptoms persist and/or the presumed diagnosis of pulmonary embolism is not confirmed.
