[Soft tissue alveolar sarcoma: Study of two cases with bones envolvement]

We report two cases of alveolar soft part sarcoma associated with bone involvement. The first case concerned a 61-year old female patient with a left sus-clavicular mass and the second a 67-year old male patient with a tumor of the left hand. The bone involvement, observed on skeletal radiography, was histologically confirmed. Surgery was the treatment in both cases, followed by radiotherapy in one case. Alveolar soft part sarcoma is a rare soft tissue malignant tumor with a local slowly growing and pejorative prognosis. If metastasis of lung, brain and bone are often present at diagnosis, the local bone involvement is not well documented
