Abstract :
Synovial sarcoma is a malignant mesenchymal tumour which mostly affects young adults and is mostly seen in extremities. Primary synovial sarcoma arising from the lung is rare, accounting for less than 0.5% of all lung carcinomas. Most commonly it arises from the lung followed by pleura and mediastinum. Primary pulmonary synovial sarcoma is an extremely aggressive malignant tumour that can invade adjacent organs and give distant metastasis. Histologically it is of two main types – monophasic and biphasic. IHC is a must for diagnosis following clinical examination and imaging. Here we report a case of an elderly male with right lung mass lesion infiltrating the visceral and mediastinal pleura. PET – computerized tomography (CT) guided biopsy was s/o synovial sarcoma monophasic type which was further confirmed by IHC. The multimodality treated for this includes wide resection, chemotherapy and radiotherapy. Synovial sarcoma is relatively chemosensitive though it is considered as a high grade tumour with a poor prognosis. Because of the advanced stage of the disease our patient was not a candidate for surgery and was taken up for chemotherapy. He had a survival of 6 months but had succumbed due to non – cancer related cause.
