Tumors of the female genital tract may be associated with a variety of unusual clinical manifestations. Uncommon endocrine and paraendocrine syndromes include production of human chorionic gonadotropin by tumors other than those of germ cell origin, hyperthyroidism associated with struma ovarii and gestational trophoblastic disease, the carcinoid syndrome, the Zollinger-Ellison syndrome, hypercalcemia, Cushing's syndrome, hypoglycemia, hypertension related to renin or aldosterone production, hyperprolactinemia, inappropriate secretion of antidiuretic hormone, and virilization associated with Nelson's syndrome and placental site trophoblastic tumor. Paraneoplastic syndromes associated with gynecological tumors include disorders of the nervous system, connective tissue, and skin, as well as hematologic abnormalities and the nephrotic syndrome. Heritable and other congenital syndromes associated with these tumors are the Peutz-Jeghers syndrome, the nevoid basal-cell carcinoma syndrome, Ollier's disease and Maffucci's syndrome, hereditary leiomyomatosis, ataxia-telangiectasia, von Hippel-Lindau's disease, thyroid abnormalities associated with Sertoli-Leydig cell tumors, and Carney's complex. Other syndromes associated with tumors of the female genital tract include Meigs' syndrome, hyperamylasemia, uveal melanocytic lesions, and pyrexia.

We recently identified two novel aminopeptidases, placental leucine aminopeptidase (P-LAP) and adipocyte-derived leucine aminopeptidase (A-LAP). Enzymatically, P-LAP degrades oxytocin, vasopressin, and angiotensin III, while A-LAP degrades angiotensin II and kallidin. In this study we investigated the expression and localization of P-LAP and A-LAP in human trophoblastic cells in the normal placenta (n = 26), gestational choriocarcinoma (n = 8), and placental site trophoblastic tumor (n = 3). On immunoblot analysis both P-LAP and A-LAP proteins were detected in normal placenta and five choriocarcinoma tissues, as well as in two choriocarcinoma cell lines. Immunohistochemical staining of normal placental tissues demonstrated that P-LAP was not only localized in villous syncytiotrophoblasts but also highly expressed in extravillous trophoblasts (EVTs) invading the decidua or maternal spiral arteries. The expression level of P-LAP on these invasive EVTs reached a maximum during the late first to second trimesters of pregnancy, and it decreased in the third trimester. Similarly, A-LAP was strongly expressed in EVTs invading the decidua or spiral arteries in the second trimester of pregnancy, while it was weakly or moderately expressed in villous cytotrophoblasts or EVTs located in the cell columns. These two aminopeptidases were more strongly expressed in all eight choriocarcinomas and three placental site trophoblastic tumors and mainly localized to the intermediate-type trophoblastic tumor cells invading the uterine myometrium or stromal vessels. In summary P-LAP and A-LAP were predominantly expressed in the invasive phenotype of EVTs during placentation, as well as in the invasive tumor cells of trophoblastic neoplasms. These results suggest the involvement of these aminopeptidases in invasiveness of both normal and malignant intermediate-type trophoblasts possibly through degradation of specific peptide substrates.
