A 23-year-old female presented with a big hard fixed swelling in right supraclavicular region for 15 years. X-Ray chest posterior-anterior view presented Homogenous opacity in upper lobe of right lung. USG of neck showed large heterogeneous lobulated almost avascular solid mass in right side of root of neck and anterior upper mediastinum may be associated with Schwannoma/ paraganglioma/soft tissue sarcoma. Spindle cell lesion was reported by FNAC. MRI showed large slightly lobulated mass along right side of root of neck and right side of superior mediastinum. A large soft tissue density mass along right side of neck and superior mediastinum was found in CT scan. Surgical excision was done successfully. Histopathological examination revealed spindle cell tumor favoring synovial sarcoma in the neck tissue and metastatic spindle cell tumor in the lung lesion.
