[Low grade pulmonary sarcoma preceding the discovery of a uterine primary].
BACKGROUND
Low grade pulmonary sarcomas are very rare tumours. We report the case of a low grade sarcoma of the lung occurring two years prior to the finding of a uterine primary.


METHODS
Complete surgical excision of a low grade pulmonary sarcoma was performed. The initial search for dissemination was negative. Two years later a follow-up scan discovered a uterine mass as well as a para-aortic shadow that proved to be the primary tumour (low grade uterine sarcoma) and a metastasis.


CONCLUSIONS
This is the second case of a pulmonary metastasis discovered before a primary low grade uterine sarcoma. The first was found during the investigation of a pulmonary sarcoma. The main differential diagnosis to consider is metastatic leiomyosarcoma. In both cases their finding justifies the search for a uterine primary by immunohistochemical examination for oestrogen and progesterone receptors as well as pelvic ultrasound or even magnetic resonance imaging.
