Complete hydatidiform moles (CHMs) and partial hydatidiform moles (PHMs) represent different clinicopathologic entities with characteristic morphologic and cytogenetic findings. In the absence of cytogenetic data, the histologic distinction between these lesions and abortuses showing hydropic swelling (AHS) may be difficult. An immunocytochemical study analyzing the distribution of human chorionic gonadotropin (hCG), human placental lactogen (hPL), and placental alkaline phosphatase (PlAP) in CHMs, PHMs, and AHS was undertaken to determine whether the expression of these trophoblastic proteins might assist in the differential diagnosis. A total of 24 CHMs, 22 PHMs, and 13 AHS were selected on the basis of established morphologic criteria. Thirty-four specimens of abortuses without hydropic swelling and normal placentas, ranging from 6 to 24 weeks gestational age, were similarly analyzed. The immunocytochemical localization of the three trophoblastic proteins, predominantly in syncytiotrophoblast (ST), was scored using a semiquantitative scoring system. In CHMs hCG is widely distributed and PlAP is patchily distributed in ST regardless of the gestational age, whereas hPL tends to increase with increasing gestational age. In contrast, in PHMs hPL is more widely distributed in ST compared with CHMs regardless of gestational age, while PlAP increases with increasing gestational age; in PHMs the distribution of hCG is markedly less than in CHMs except early in the first trimester when the staining patterns are similar. The different patterns of distribution of hCG, hPL, and PlAP may reflect differences in the pathobiology of trophoblast in CHMs and PHMs and appear to be useful in the differential diagnosis of these conditions.
