Metastasis Relapse in Synovial Sarcoma of Parotid Gland Followed by Neuropathies and Tissue Damage: A Case Report

Synovial sarcomas are a heterogeneous group of tumors, accounting for 1-2% of adult cancers worldwide. Formation of synovial sarcoma after tissue and nerve injury, radiations induced neuropathies and latent metastasis is those events which are still controversial and need more research. In this report, we present the case of an 18-year-old female patient who developed synovial sarcoma followed by a punch to the face. MRI showed lobulated lesion of 4x3cm appreciated in left parotid space. In spite of Parotidectomy, radiotherapy and radiosurgery followed by MRI and CT-scan latent metastasis was raised in lungs which leads to demise of patient. There are numerous potential etiologic and neurological factors for the development of latent metastasis in synovial sarcoma. Here we will summarize all factors and its complications according to the current literature.
