    Epithelioid trophoblastic tumor of the endocervix: A case report
    (Academic Press Inc Elsevier Science, 2002) Meydanli, MM; Kucukali, T; Usubutun, A; Ataoglu, O; Kafkasli, A
    Background. It is difficult to recognize epithelioid trophoblastic tumor (ETT) as a trophoblastic disease because of its rarity and growth pattern simulating a carcinoma. Case report. A 36-year-old woman with stage IB1 squamous cell carcinoma of the uterine cervix and a high serum beta-human chorionic gonadotropin (beta-hCG) level underwent radical hysterectomy with pelvic and para-aortic lymphadenectomy. However, light microscopic findings and immunohistochemical studies with pan-cytokeratin, epithelial membrane antigen, inhibin-alpha, beta-hCG, and human placental lactogen revealed ETT of the endocervix. The patient is alive with no evidence of disease 12 months after surgery. Conclusion. Before the patient is resorted to radical surgical interventions for assumed cervical carcinoma, ETT should be ruled out in women of reproductive age with endocervical tumors and elevated serum beta-hCG levels.

    Rare case of neuroendocrine small cell carcinoma of the endometrium with paraneoplastic membranous glomerulonephritis
    (Pensiero Scientifico Editor, 2003) Meydanli, MM; Erguvan, R; Altinok, MT; Ataoglu, O; Kafkasli, A
    Small cell carcinomas are well-recognized tumors known to occur predominantly in the lung. These neoplasms are occasionally associated with a variety of paraneoplastic syndromes. Four cases of paraneoplastic glomerulopathy associated with small cell lung carcinoma have been reported. However, there have been no reports in the literature indicating an association between endometrial small cell carcinoma and paraneoplastic glomerulopathy. We report a case of neuroendocrine small cell carcinoma of the endometrium associated with membranous glomerulonephritis (MGN), which appeared to be a component of an unusual paraneoplastic syndrome. A 33-year-old multiparous woman presented with abnormal vaginal bleeding and abdominal bloating. Endometrial biopsy revealed neuroendocrine small-cell carcinoma of the endometrium. On the eighth day of hospitalization the patient suddenly developed renal failure. Renal biopsy revealed MGN, probably due to tumor-antigen-related immune complex deposition. Small cell carcinoma of the endometrium may be associated with paraneoplastic MGN. Medical staff should take into account the possibility of a preexisting glomerular injury when managing a patient with small cell carcinoma of the endometrium.

    Uterine metastasis from infiltrating ductal carcinoma of breast in a patient receiving tamoxifen
    (Churchill Livingstone, 2002) Meydanli, MM; Karadag, N; Ataoglu, O; Kafkasli, A
    The established relationship between tamoxifen and the development of endometrial cancer causes differential diagnostic problems between metastatic and primary uterine neoplasms. A 45-year-old woman underwent modified radical mastectomy because of left-breast cancer. She presented with abnormal vaginal bleeding 6 years later, while still on tamoxifen therapy. The endometrial curettage revealed undifferentiated adenocarcinoma. She underwent total abdominal hysterectomy, bilateral salphingoopherectomy as well as pelvic and periaortic lymphadenectomy. Microscopic examination revealed neoplastic cells which formed sheets and duct-like structures in the endometrium. The pattern was not that of a primary endometrial tumour and an immunohistochemical staining was performed using human breast gross cystic disease fluid protein-15 (GCDFP-15) which was found out to be positive in the tumour cells. A diagnosis of metastatic ductal carcinoma of the breast in the uterus was rendered. Uterine metastasis should be kept in mind in patients with a history of breast cancer who are on tamoxifen therapy. (C) 2002 Elsevier Science Ltd. All rights reserved.
