[A rare tumor of the chest wall: the synovialosarcoma]

Metastatic pulmonary synovial sarcoma: A double coincidence: Case report

Synovial sarcomas are considered as one of the most aggressive neoplasms that account for approximately 8% of all soft tissue sarcomas; they are mainly localized in soft tissues of the extremities and joints and rarely occur in the thorax. In this case report, we describe a 34-year-old woman presenting a chest pain with a chest radiography showing a mass lesion occupying two-thirds of the right hemi-thorax. A malignant pulmonary tumor was suspected after CT imaging revealing a bilateral renal metastasis, and then a spindle-cell carcinoma was thought-about. The post-operative pathological analysis of the main mass confirmed the diagnosis of a pulmonary synovial sarcoma.

Primary thoracic synovial sarcomas: A case report

Primary pulmonary synovial sarcoma (SS) is a rare neoplasm. Its clinicoradiologic attributes are not yet well defined. We report the observation of a patient followed for primary pulmonary synovial sarcoma. We report the radio‐clinical features of this rare tumor.

Primary Pleuropulmonary Synovial Sarcoma: A Case

Primary pleuropulmonary synovial sarcoma is extremely rare. The diagnosis can only be made after having eliminated an extrapleuropulmonary localization in the past and at the time of diagnosis. Our presentation is about a 40-year-old woman having a cough and dyspnea since three weeks ago; imaging had showed a left pleurisy with pleuropulmonary process. Histological study of the biopsy confirmed the diagnosis of pleuropulmonary synovial sarcoma. PET-SCAN had not identified any extrathoracic localization. This tumor is known for its aggressive nature and high risk of metastasis. Its primitive character is retained following a diagnostic procedure of exclusion. Surgical treatment remains the best therapeutic tool when it is technically feasible; otherwise the prognosis is often unfortunate. In this paper, we report a case of primary pleuropulmonary synovial sarcoma. Through this case, we present a rare disease that is often difficult to diagnose.

[Initial manifestation and atypical site for metastatic synovial sarcoma in an immunocompetent adult patient: about a case and literature review]

Synovial sarcoma (SS) is a rare tumor. It is characterized by various sites of occurrence but rarely involves the chest. The tumor may be wrongly diagnosed as benign due to its slow growth. Less than 10% of patients present with metastatic cancer. Endobronchial metastases are exceptional. Immunohistochemical examination and cytogenetic analysis allow to distinguish it from other mesenchymal tumors. The presence of SYT-SSX fusion transcript allows the diagnosis. Surgery is used for localized tumors that can be treated with radiation therapy while chemiotherapy is used for metastatic tumors. The average rate of locoregional or metastatic recurrence two years after SS is 50%. We report the case of a 28-year old patient with metastatic SS characterized by its uncommon metastatic site. He presented with endobronchial metastasis revealing his disease, that had evolved for more than 2 years. The SS is life-threatening due to its slow and insidious growth. Prognosis is guarded. This study aimed to emphasize this atypical site for metastatic synovial sarcoma as well as to insist on the role of early diagnosis and treatment.
