Giant cell rich osteosarcomas, histological variant of conventional osteosarcomas account for 3% of all cases of osteosarcomas and most of them are arise from the appendicular skeleton. Giant cell rich osteosarcomas have been rarely reported in the head and neck region. This is the first case report of giant cell rich variant of osteosarcoma in the maxilla. It is important to recognize this variant, as its prognosis is worse as compared to conventional osteosarcomas of the head and neck region. We here present a case of giant cell rich variant of osteosarcoma of the maxilla and along with its characteristic radiological and histopathological picture.
富含巨细胞的骨肉瘤是传统骨肉瘤的组织学变体,占所有骨肉瘤病例的3%,其中大多数起源于四肢骨骼。头颈部区域很少报道富含巨细胞的骨肉瘤。这是上颌骨骨肉瘤富含巨细胞变体的首例病例报告。认识到这种变体很重要,因为与头颈部区域的传统骨肉瘤相比,其预后更差。我们在此报告一例上颌骨骨肉瘤富含巨细胞变体病例,并展示其特征性的放射学和组织病理学表现。
