Recurrent Fibrosarcoma with Recurrent Pericardial Metastasis Rare Primary Tumour and Unusual Metastasis: A Case Report

Mandibular fibrosarcoma is a rare type of malignant jaw tumour. A diagnosis is typically made following imaging and biopsy tests, and the primary treatment is surgery, often in combination with chemotherapy or radiotherapy. Fibrosarcomas have the potential to metastasise, meaning that the cancer can spread to other parts of the body. Metastatic tumours in the pericardium are among the least understood, and are generally associated with a poor prognosis. To date, the number of systematic studies devoted to this topic has been limited. In this report, we present the case of pericardial metastasis from recurrent mandibular fibrosarcoma in a young patient. The disease was characterised by recurrent metastasis. Unfortunately, our patient’s latest assessment, which was carried out recently, revealed a recurrence of a paracardiac mass, this time in the precordial region.
