Pericytoma with t(7;12) and ACTB-GLI1 fusion arising in bone
2012
Summary Cytogenetic analysis of a primary bone neoplasm with pericytic features in a 67-year-old man revealed a t(7;12)(p22;q13) among other karyotypic abnormalities. Subsequent molecular studies confirmed the presence of an associated ACTB-GLI1 fusion transcript. An identical 7;12 translocation is known to characterize a discrete group of soft tissue tumors belonging to the myopericytic category termed pericytoma with t(7;12) . To the best of our knowledge, this is the first case of pericytoma with t(7;12) arising in bone. Cytogenetic and molecular analyses were useful, if not essential, in classifying this rare diagnostic entity.
