Chordoid meningioma is a rare histological subtype of meningiomas. Cytogenetic analysis of three cases revealed the unique feature of an unbalanced translocation der(1)t(1;3)(p12–13;q11) that was ascertained by chromosome microdissection and reverse fluorescence in situ hybridization. As the t(1;3) has not been observed in other subtypes of meningioma, it may represent a specific cytogenetic marker of chordoid meningiomas. It is not yet clear whether a fusion gene or the combined loss of genes from chromosome arms 1p and 3p is the pathogenetically important outcome of the translocation.
