Abstract
Dedifferentiated liposarcoma (DDLS) has a relatively poor prognosis, however this neoplasm rarely occurs in the head and neck. To date, no definite protocol has been established for the diagnosis and treatment of head and neck DDLS. The present study reports the case of a 69-year-old male patient with DDLS of the oral floor. To the best of our knowledge, this is the first documented case of oral floor DDLS. In addition, this is the first reported case with the development of a second primary malignancy following the treatment of head and neck DDLS. A literature review of 50 cases of head and neck DDLS revealed that preoperative biopsy is not reliable for the diagnosis of these tumors and an accurate pathological diagnosis with total resection is preferred.

Abstract
Sarcoma is an uncommon histopathological presentation of sinonasal tumors, comprising ~15% of all cases; liposarcoma is particularly uncommon. An analysis of the available medical literature revealed no prior reports of dedifferentiated liposarcoma (DDLPS) of the sinonasal cavity. This case report presents a rare case of DDLPS of the sinonasal cavity. A 40-year old six-week pregnant female was admitted with a left nasal obstruction. Endoscopic evaluation of the left nasal cavity revealed a polypoid lesion. A computed tomography scan indicated a mass invading the left nasal cavity, maxillary sinus and anterior ethmoid sinus with focal destruction of the surrounding bone. A biopsy of the tumor was performed and hematoxylin and eosin staining of the tissue sections revealed proliferation of atypical and pleomorphic spindle cells with enlarged or elongated hyperchromatic nuclei and occasional vacuolated cytoplasm arranged in short interlacing fascicles or storiform structures, accompanied by tumor necrosis. These findings were consistent with undifferentiated pleomorphic sarcoma. Immunohistochemically, the tumor cells were positive for cyclin dependent kinase 4, mouse double minute 2 homolog (MDM2) and adipophilin. Fluorescence in situ hybridization (FISH) analysis revealed amplification of the MDM2 gene. Recently, undifferentiated pleomorphic sarcoma without areas of well-differentiated liposarcoma but with MDM2 amplification is regarded as conventional DDLPS. In the present case, the tumor was diagnosed as a DDLPS due to the results of histopathological, immunohistochemical and FISH analysis.
