Xanthogranuloma of the sellar region.

The incidence of diagnosed xanthogranuloma of the sellar region is very low [1, 2, 5, 6]. We report about two cases 1) in a 57-year-old female and 2) in a 5-year-old boy. In both cases radiographic findings revealed an inhomogeneous, contrast enhancing sellar lesion. Histopathology showed the typical features of a xanthogranuloma of the sellar region with cholesterol clefts, lympho-plasmacellular infiltrates, marked hemosiderin deposits, multinucleated foreign body giant cells around cholesterol clefts, accumulation of macrophages and only small epithelial cell clusters [6]. As xanthogranuloma of the sellar region are rarely diagnosed we want to draw attention to this rather unusual diagnosis.
