An unusual case of a 37‐year‐old female with xanthomatous bone tumor of the right molar area of the mandible was presented. The tumor was asymptomatic and found to be a well‐demarcated intraosseous radiolucent lesion on radiographic examination. Histologically the tumor consisted of two cell types, fibroblastic and xanthomatous cells. There was no osteoid, bone or cartilage formation. However, numerous psammomatous calcified bodies were seen in the fibrous area. Ultrastructural study showed fibroblastic cells in different stages of proliferation as the basis of the tumor which transform itself into xanthomatous cells. From the clinicopathologic findings, our case was thought to be a xanthic variant of non‐ossifying fibroma (so‐called xanthofibroma) of the mandible.
