ABSTRACT

Background: Soft tissue leiomyosarcomas are malignant tumors of mesenchymal origin that are rarely found in the head and neck. They are more prevalent in women between the fifth and sixth decades of life. They have no specific clinical or imaging manifestations, so the definitive diagnosis is by histological examination supported by immunohistochemical techniques. Local recurrences are common and tend to metastasize hematogenously. Case presentation: Female patient of 49 years who attends the Manuel Ascunce Domenech University Hospital in Camaguey, due to an increased volume of right frontotemporal region and ocular propotosis of a rapid and progressive course. Studies of computed tomography and magnetic resonance imaging of skull and orbit showed a well defined heterogeneous lesion, which infiltrated epicranial soft and bone tissue and invaded the orbit. Surgery was made with exeresis of the lesion en bloc and the histological study showed a leiomyosarcoma of intermediate-degree malignancy. Radiotherapy was started during which recurrence of the injury was found and this led to reoperation. Conclusions: Postoperative evolution was favorable but metastases were found in lung and lymph nodes.
