MAML2 and Tako-tsubo cardiomyopathy: In an effort to estimate the prognostic value of MAML2 rearrangement in refining clinicopathological prognostic factors in PMEC and determine its potentiality in discriminating PMEC from morphologic mimics, we detected the prevalence of the rearrangement nature of MAML2 by using fluorescence in situ hybridization (FISH) in tissue samples obtained from 42 cases of PMEC and 40 of ASC.
