Primary monophasic synovial sarcoma lung with brain metastasis diagnosed on transthoracic FNAC: Report of a case with literature review.

Synovial sarcoma is highly malignant tumor of soft tissues, occurring chiefly in the extremities and limb girdle with a propensity for local recurrence and sometimes metastases to the lungs. Primary synovial sarcoma arising in the lungs is rare and brain metastasis as presentation is further uncommon. We report a case of primary monophasic synovial sarcoma lung presenting with brain metastasis in a 35-year-old male patient.
