Soft tissue sarcomas are rare tumors representing 1% of all malignancies and less than 10 % concerning head and neck tumors. We are presenting the case of a 42 year old patient that was admitted in our service for a giant laterocervical tumor (15/12/10 cm). We performed total excision of this tumor en bloc with the involved tegument; the resulting defect was covered with a split thick skin graft. The weight of the tumor was 500 g. Histopathological examination revealed an intermediate-grade fibrosarcoma. The postoperative evolution was good; radiotherapy was indicated.
