ABSTRACT

Malignant peripheral nerve tumor, also known as malignant neurogenic sarcoma, arise on Schwann cells and is usually associated to neurofibromatosis type 1 and 2. The most common location is on the extremities and is more frequent in males in middle age. The malignant schwannoma is an uncommon tumor and represents less than 1% in thoracic members, proportion that increases to 7% in children. Symptoms depend on the involved nerve. We present a case of a 24 years old woman, whose initial symptoms started ten months before her admission, with increase of volume in the upper back region and in the right shoulder, with slow and progressive growth, as well as with pain. The ultrasound and computerized tomography scan was performed; soft tissue tumor was the diagnosis of the biopsy, the histological result was malignant schwannoma.
