A few studies have described a limited extent of p57 expression (scattered nuclear positivity in villous cytotrophoblast and villous stromal cells) in a minority of cases of both diploid and tetraploid CHMs; this limited extent of expression (present in <10% of these cell types) is still considered compatible with a diagnosis of CHM.
