Immunohistochemical characterization of p57(KIP2) expression in early hydatidiform moles.
Human Pathology 2002 December
The differentiation of complete mole (CM), an aberrant androgenetic conceptus, from partial mole (PM) and hydropic abortion (HA) in early gestations is very important for patient management. In this study, 10 diploid voluntary artificial abortions (ABs), 20 diploid HAs, 20 triploid PMs, and 44 diploid CMs (including 4 persistent diseases), all of which were in the first trimester, were evaluated by immunohistochemistry of formalin-fixed tissues using a monoclonal antibody against p57(KIP2) protein (p57), a putative paternally imprinted inhibitor gene. DNA ploidy in all cases was analyzed by flow cytometry. In all ABs, nuclear p57 was strongly expressed in cytotrophoblasts, intermediate trophoblasts, villous stromal cells, and decidual stromal cells but was absent in syncytiotrophoblast. In diploid CMs, p57 expression in cytotrophoblasts and villous stromal cells was either absent (37 cases) or very low (7 cases). Villous intermediate trophoblasts stained for p57 in 12 cases of CM. On the other hand, 16 HAs and 19 PMs showed p57 levels comparable to those observed in ABs. Decidual stromal cells provided a reliable internal control in all cases. These findings support the hypothesis that misexpression of p57 is involved in the abnormal development of androgenetic CMs. This immunohistochemical analysis is a useful tool for the differential diagnosis of CMs.
