摘要：
Atypical Lipomatous Tumor/Well Differentiated Liposarcoma (ALT/WDLS) is a soft tissue sarcoma of intermediate malignant behavior, most frequently affecting the retroperitoneum and lower extremities. Oral liposarcomas are very rare neoplasms, the most common histological subtype being ALT/WDLS. In this study, three additional cases of ALT/WDLS located on the tongue (2 cases) and the lower lip (1 case), respectively, are described. Analysis of the salient clinicopathologic features of 63 oral ALT/WDLS cases previously reported in the English language literature, as well as of the 3 cases presented in this study, indicates that the indolent biologic behavior of this tumor justifies its designation as a locally spreading malignant neoplasm, affording a rather conservative surgical approach. © 2012 Springer Science+Business Media, LLC.
