Liposclerosing myxofibrous tumor (LSMFT) is a benign fibro-osseous lesion that is characterized by a complex mixture of histologic elements, including its fibrous dysplasia-like features and its lipoma, myxofibroma, xanthoma and pseudo-Paget's bone patterns. However, this lesion is considered by some researchers as a variant of fibrous dysplasia or as the non-specific end result of degenerative change, while it is considered by others as a definite clinicopathologic entity. Here, we report on a case of LSMFT occurring in tibia, which is a very uncommon location for this tumor, and we review the related literatures. The case presented here shares features with those described for LSMFT, except for the location of this tumor. We believe that more studies on a larger scale that compare LSMFT with other benign bone lesions, including fibrous dysplasia, are required to clarify the origin and behavior of this lesion.
