Clonal rearrangement of 15p11.2, 16p11.2, and 16p13.3 in a case of nodular fasciitis: additional evidence favoring nodular fasciitis as a benign neoplasm and not a reactive tumefaction

This article describes a case of nodular fasciitis with the karyotype 47,XY,+4[3]/46,XY,add(15)(p11.2), t(16;16)(p13.3;p11.2)[2]. The presence of clonal chromosomal abnormalities in this case, as well as in three previously reported cases, indicates that nodular fasciitis is a benign neoplasm and not a reactive lesion.
