RESUMO
The neck, being not protected by skeleton, is vulnerable to external trauma and injury which can involve blood vessels, muscles, nerves, and trachea. Carotid injuries can be potentially life-threatening by hemorrhage and stroke. We present a case of a 26-year-old manual worker who presented a neck injury caused by a metallic projectile. The injury involved the right common carotid artery with an internal jugular vein fistula, and tracheal damage. The patient was managed with surgical repair of the tracheal lesion, reconstruction of the carotid section using a PTFE graft bypass, and ligation of the internal jugular vein. In the immediate postoperative period, the patient presented with no neurological deficits, but he did develop a pulmonary infection that resolved with antibiotic therapy. The follow-up is now 3months. The patient is doing well without any neurological disorder.

INTRODUCTION: Malignant teratomas can be either immature teratomas or they can develop after treatment of other malignant germ cell tumors with chemotherapy or radiotherapy. Spontaneous malignant transformation of mature teratomas is very rare. OBSERVATION: We report the case of a patient complaining of atypical chest pain. Chest plain radiography showed a right anterior mediastinal mass. Computed tomography revealed a heterogeneous mediastinal mass with fat areas and calcification. There were hilar and mediastinal lymph nodes as well as lung parenchymal nodules. CT-guided and then surgical biopsies confirmed the diagnosis of a mature teratoma, which had degenerated into a digestive adenocarcinoma. CONCLUSION: Spontaneous malignant transformation of mature mediastinal teratoma is very rare. The diagnosis of malignant transformation is based on radiological examinations, laboratory tests and histological studies.
