Abstract:
Objective To study the signification of p57kip2 immunostaining to distinguish molar gestations from hydropic abortions.Methods To observe the p57kip2 immunohistochemical expression in 58 cases of histological hydropic villi which were divided into complete mole(18 cases) ,partial mole(19 cases),hydropic abortion(11 cases)and undetermined hydropic abortion or molar gestations(10 cases) and in 3 normal placentas.Results Normal villi,partial mole and hydropic abortions show positive staining for p57kip2, which expressed in the nuclei of cytotrophoblast and villous mesenchyme,and complete moles show complete absence of staining in the cytotrophoblast and villous mesenchyme.According to the comparison of the diagnosis based on morphology and the one based on p57kip2 stai-ning,the later whose sensitivity is 96% (46/48) confirmed the earlier diagnosis in 58 cases studied and the later conformed to the earlier very well.Conclusion The immunohistochemical staining for p57kip2 is a valuable diagnostic mean to distinguish molar gestations from hydropic abortions and is a sensitive and specific marker for the diagnosis of complete mole.
