EP1.15-04 Huge Intra Thoracic Mesenchymal Tumors. About 19 Cases

Abstract

Mesenchymal tumors represent a heterogeneous group of tumors, which may be benign or malignant and are developed from supportive tissues: connective, vascular, nervous or adipose tissues. They often reach large volumes making their care very difficult. Our work consists of a retrospective study of 19 cases, collected in the department of thoracic surgery of Rabat; over a period of 7 years from January 2011 to December 2018. The purpose of this work is to update the diagnostic approach of this type of tumor, and also their anesthetic and surgical management. We counted 19 cases including 12 women and 7 men, with an average age of 49 years. Dyspnea and chest pain are the main symptoms found in all our patients. All the patients received an X-ray and thoracic CT scan, 13 patients underwent a transparietal biopsy and were inconclusive in 3 patients. The surgical approach was a posterolateral thoracotomy for 16 patients, a mean lobectomy completing tumor resection was performed on one patient. The average size of the operative pieces was 16 cm. In operation 5 patients presented hemodynamic instability, 12 patients required a transfer to the intensive care unit in the immediate postoperative. The anatomopathological study of operative specimens returned to solitary fibrous tumor (8 patients) Neurogenic tumors (4 patients) Teratoma (2 patients) Liposarcoma (1 patient) Metaplastic thymoma (1 patient) Synoviosarcoma (1 patient) Pneumoblastoma (1 patient) ) fibromatosis (1 patient). The diagnosis of an intra-thoracic mesenchymal tumor is very difficult, but it must in no way delay surgical management as long as it is possible.
