1/384. Uterine malignant leiomyoblastoma (epithelioid leiomyosarcoma) during pregnancy.

    A case of uterine malignant leiomyoblastoma (UML) which was initially mistaken for uterine leiomyoma on two different occasions is presented. About 20 cases of uterine leiomyoblastoma taking a malignant course have been described in the literature. This case of UML is the first diagnosed during pregnancy. In retrospect, tumor tissue removed from the uterus 4 years earlier already showed histological signs of UML. The large and metastatic tumor showed nuclear atypia, a moderate mitotic index, and tumor cell necrosis, indicating malignancy. Treatment consisted of hysterectomy, bilateral salpingo-oophorectomy, and debulking of most other tumor masses. In the literature, radio- and chemotherapy have not proved to be effective in these tumors. Hormonal therapy has only been used in 2 patients. In this patient, hormonal influence on tumor growth may be substantial. The tumor was progesterone- and estrogen-receptor positive and increased in size rapidly during pregnancy. Since little is known about these tumors further studies are necessary to evaluate hormonal influences both as a causative factor and as a therapeutic possibility.

2/384. Malignant mixed Mullerian tumor with rhabdoid features: a report of two cases and a review of the literature.

    Rhabdoid tumors were originally described as a type of pediatric renal neoplasm that contains cells resembling rhabdomyoblasts but lacking muscle differentiation. Extrarenal rhabdoid tumors have since been reported in multiple anatomic sites in the pediatric and adult population. These tumors are characterized by an aggressive clinical course, resistance to treatment, and a rapidly fatal outcome. Eight cases of uterine neoplasms with rhabdoid differentiation have been previously reported. In the three cases where clinical follow-up was available, the patients died of disease within 3 to 17 months after the diagnosis was established. We report two cases of uterine malignant mixed Mullerian tumor (carcinosarcoma) with rhabdoid differentiation. The findings and clinical outcome confirm the aggressive nature of uterine tumors with rhabdoid differentiation. One of the patients died of disease 3 months after initial operative treatment while the other patient's tumor recurred in 1 month and she died within 10 weeks. The poor prognosis of these neoplasms makes their histopathologic recognition important.

3/384. molar pregnancy presenting with hyperemesis gravidarum.

    nausea and vomiting are common complaints in pregnancy, occurring in more than 50% of pregnant women. Occasionally, the vomiting becomes severe and persistent enough to develop into the syndrome called hyperemesis gravidarum and sometimes requires hospitalization. A 20-year-old woman presented with hyperemesis gravidarum, which was later found to be associated with a molar pregnancy. hyperemesis gravidarum is reported to occur in as many as 26% of molar pregnancies. Increases in the level of serum beta-human chorionic gonadotropin may be the mechanism of hyperemesis gravidarum in molar pregnancy. Hyperthyroid states linked to molar pregnancy may further exacerbate hyperemesis gravidarum. physicians should be aware of this possibility of molar pregnancy in all patients with hyperemesis gravidarum and be familiar with the appropriate management to monitor and prevent an often-fatal trophoblastic neoplasm.

4/384. Abnormal uterine bleeding as a presenting sign of metastases to the uterine corpus, cervix and vagina in a breast cancer patient on tamoxifen therapy.

    Metastases to the female genital tract from extragenital cancers are uncommon. The ovaries are most often affected with the breast and gastrointestinal tract being the most common sites of the primary malignancy. Metastases to the uterus from extragenital cancers are significantly rarer than metastases to the ovaries and in the majority of cases the ovaries are also involved. A case of metastases restricted to the uterine corpus, cervix and vagina from breast carcinoma, without involvement of the ovaries, is described. The patient who had been on tamoxifen therapy presented with postmenopausal bleeding. The diagnosis of uterine metastases was established during endometrial ablation and confirmed by total abdominal hysterectomy and bilateral salpingo-oophorectomy. This case illustrates that abnormal uterine bleeding in a breast cancer patient, regardless of whether she is receiving or not receiving tamoxifen, should always alert the physician to consider the possibility of uterine metastases from breast carcinoma.

5/384. pregnancy with primary tubal placental site trophoblastic tumor--A case report and literature review.

    Placental site trophoblastic tumor (PSTT) is a rare trophoblastic neoplasm with malignant potential. The diagnosis and prognosis of this rare disease remain difficult. A case of tubal PSTT with the primary manifestation of internal bleeding at 30 weeks' gestation is presented. Emergency exploratory laparotomy and right partial salpingectomy were performed initially. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy were done immediately after cesarean section at 34 weeks' gestation. No further adjuvant therapy was given after surgery. No evidence of tumor recurrence or signs of metastasis were noted during 12 months of follow-up. Heterotopic pregnancy, one with intrauterine normal pregnancy and the other with implanting in the right fallopian tube and placental site trophoblastic tumor transformation, was proposed. To our knowledge, this is the first such case in the English literature.

6/384. Cotyledonoid dissecting leiomyoma (Sternberg tumor): an unusual form of leiomyoma.

    Smooth muscle tumors are the most common neoplasms of the female genital tract. While most are usually easy to diagnose, several variants pose considerable diagnostic difficulties. Recently, a new form of uterine smooth muscle tumor was described that has an infiltrative character, which was named "cotyledonoid dissecting leiomyoma" or "Sternberg tumor" due to its macroscopic similarity to the gross architecture of the placental cotyledon. This report, the second such of this tumor, describes the macroscopic, microscopic, immunohistochemical and ultrastructural features of one of these unusual cases.

7/384. Distant cutaneous metastasis from carcinoma of the uterus. A case report.

    Cutaneous metastasis from intraabdominal carcinoma is relatively rare. When it is present it is usually located in the skin overlying the neoplasm [1]. Carcinoma of the uterus metastatic to the skin accounts for 9% of all cutaneous metastases. Distant metastasis is extremely rare. Such a metastasis to the skin of the big toe of the lower limb is presented.

8/384. Multiple nodular metastases in mesenteric panniculitis by uterine papillary serous adenocarcinoma (UPSC): CT appearance of a case.

    Intra-abdominal panniculitis is a thickening of the mesentery of the small/large intestine due to infiltration of lipid-laden macrophages associated with a variable amount of fibrosis. This condition is rarely associated with malignant neoplasms. We report the computed tomography (CT) findings of a patient treated for uterine papillary serous adenocarcinoma (UPSC). She had mesenteric panniculitis where metastatic tumor nodules implanted. This was the only intraperitoneal recurrence. To our knowledge, no such finding has been reported in the gynecologic and radiologic literature to date. On CT images, the differential diagnosis is with cystic dilatations of mesenteric lymph vessels.

9/384. Cytopathological observations in a 27-year-old female patient with endometrioid adenocarcinoma arising in the lower uterine segment of the uterus.

    The determination of the malignancy of an endometrioid adenocarcinoma arising in the lower uterine segment (LUS) is difficult because of the high degree of differentiation of adenocarcinoma. The cytopathological and immunohistochemical features of endometrioid adenocarcinoma arising in the LUS of a young adult female are presented. The preoperative cytopathological examination of a 27-yr-old female could not enable an accurate diagnosis of malignancy. hysterectomy specimens revealed the presence of an endometrioid-type adenocarcinoma with minimal atypia and myometrial invasion, which was located in the LUS. This tumor was consistent with a histological diagnosis of endometrioid minimal-deviation adenocarcinoma (MDA). Immunohistochemically, the tumor's glands were p53-, proliferating cell nuclear antigen-, and carcinoembryonic antigen-positive, and estrogen receptor-, progesterone receptor-,and vimentin-negative. The cytological and surgical specimens showed a remarkable association of squamous metaplasia. Although cytopathological difficulties in determining malignancy of MDA endometrioid adenocarcinoma arising in the LUS are well-known, the following features worth noting include: 1) squamous metaplasia on cytological and histological slides; 2) epithelial cells incorporating polymorphic nuclear neutrophils on cytological slides; and 3) positive immunohistochemistry of p53 protein.

10/384. A case of postmenopausal endometriosis unrelated to neoplasm.

    A 55-year-old woman was referred to our hospital for evaluation of a lower abdominal mass. menopause had occurred at age 52 years. ultrasonography and magnetic resonance imaging showed a partially solid right ovarian tumor, an appearance suggestive of malignancy. A transabdominal simple hysterectomy and bilateral salpingo-oophorectomy were performed. Pathologic examination revealed an endometrial cyst of the right ovary, a uterine leiomyoma, and adenomyosis.
