1/255. Ovarian cancer presenting as leukocytoclastic vasculitis.

    We describe a 53-year-old woman with a 4-month history of palpable purpuric papules on the upper and lower extremities. biopsy of the skin lesions revealed leukocytoclastic vasculitis. Although she denied any systemic symptoms, urinalysis demonstrated hematuria and proteinuria. Although the patient's skin lesions responded to prednisone, her urinalysis did not improve. A 10-cm complex mass involving the left ovary and adnexa was incidentally discovered on renal ultrasound. serum CA-125, an ovarian cancer marker, was elevated. laparotomy revealed ovarian carcinoma confined to the left ovary. After the cancer was resected, the patient's urinalysis slowly improved. Leukocytoclastic vasculitis (LCV) is infrequently associated with underlying malignancy and only rarely with solid tumors. We postulate that the patient's vasculitis represented a paraneoplastic phenomenon that allowed a diagnosis of asymptomatic ovarian carcinoma. To our knowledge, this is the first report of LCV occurring as the presenting sign of ovarian cancer.

2/255. Mediastinal lymph node metastasis of colon cancer: report of a case.

    We herein describe a patient with mediastinal lymph node metastases which occurred after both a primary sigmoid colon cancer and metachronous ovarian metastasis had been resected. The most likely route of metastases to the mediastinum in this case is the paravertebral venous plexus probably connected to the ovarian metastasis, or so-called remetastasis. This case illustrates that the mediastinum is thus a possible metastatic site in patients with colon cancer. Surgeons should therefore pay attention to the mediastinum as well as the lung fields when checking chest X-ray films during a follow-up of patients after a resection of colon cancer.

3/255. Ovarian hepatoid yolk sac tumours: morphological, immunohistochemical and ultrastructural features.

    AIM: The clinicopathological, immunohistochemical and ultrastructural features of two ovarian hepatoid yolk sac tumours (H-YST) from our files are reviewed. methods AND RESULTS: Using avidin-biotin-peroxidase complex technique, the immunoprofile of these tumours was compared to that of a classic yolk sac tumour and to that previously reported for hepatocellular carcinomas. The clinicopathological and morphological features of our cases are similar to the seven previously reported ovarian cases. This rare germ cell tumour occurs in young females (mean age = 17.6 years) and presents most commonly with abdominal pain and a large ovarian mass (average size = 140 mm). Histologically, the tumours display a striking resemblance to hepatocellular carcinoma. The absence of an associated typical pattern of yolk sac tumour or other germ cell neoplasm may make it difficult to recognize the germ cell origin of this lesion. Our cases demonstrated positive staining for alpha-fetoprotein and alpha-1-antitrypsin. In addition, there was immunoreactivity with polyclonal carcinoembryonic antigen (CEA) antiserum in a canalicular pattern, focal staining for inhibin, oestrogen and progesterone receptors and absence of immunoreactivity for CK7 that contrasts with the immunophenotype of a usual yolk sac tumour. CONCLUSIONS: Ovarian H-YST and hepatocellular carcinoma share a similar immunoprofile. Ovarian H-YST is a highly aggressive tumour, most patients exhibit recurrence or die of disease within 2 years of diagnosis.

4/255. Primary angiosarcoma of the ovary: a case report and review of the literature.

    INTRODUCTION: Gynecological sarcomas are rare and have a poor prognosis. Uterine sarcomas are most common accounting for 4% of all uterine tumors. Ovarian sarcomas are less frequent and are usually carcinosarcomas. CASE REPORT: A previously healthy 40-year-old G2P2 presented for evaluation of 72 h of right upper quadrant pain and shortness of breath. A malignant right pleural effusion, ascites, and adnexal mass were found. Surgical staging and suboptimal debulking revealed pure angiosarcoma of the ovary Stage IV. DISCUSSION: There are 12 cases of ovarian angiosarcoma reported in the literature. Ten of these cases presented in advanced stages with survivals of 2-30 months. Various chemotherapy regimens have been tried on these tumors including the most recent recommendation of MAID (mesna, doxorubicin, ifosfamide, and dacarbazine) and prognosis remains poor. Our patient underwent elective right pleurodesis via video-assisted thorascopic surgery under local anesthesia for an early recurrent right pleural effusion and subsequently began MAID chemotherapy.

5/255. Managing a patient with presumed testosterone-secreting ovarian tumor.

    We report the case of a 70-year-old woman who was presumed to have right ovarian testosterone-secreting tumor and was treated with long-acting gonadotropin-releasing hormone agonist therapy plus add-back hormone replacement therapy. The patient presented with various medical problems including hypertension, intracranial hemorrhage, myocardial infarction, unstable angina pectoris, and poor control of diabetic mellitus and had exhibited rapid symptoms of androgen excess such as progressive hirsutism and bilateral temporal balding for half a year. Tumor survey was negative except for an elevated testosterone level. Renal vein catheterization successfully detected a right ovarian androgen-secreting tumor. Because the patient was deemed medically unable to tolerate surgery, she received an alternative treatment consisting of 6 months of gonadotropin-releasing hormone-agonist (GnRH-a) and add-back hormone replacement therapy (HRT). serum testosterone levels returned to normal limits after administration of the first dose of GnRH-a. A follow-up tumor survey was negative. The patient has been alive and free of disease for 8 months after six doses of GnRH-a. We conclude that this strategy might be used as urgent therapy in a medically compromised patient with presumed ovarian androgen-secreting tumor.

6/255. Accidentally delayed diagnosis of ruptured ovarian carcinoma in a young woman: a care report.

    Ovarian carcinoma commonly occurs in postmenopausal women and often presents with an insidious course. Acute abdomen is rarely an initial symptom. When these patients present with abdominal discomfort, the disease has already spread throughout the peritoneal cavity. We present a case of mucinous cystadenocarcinoma in a young woman who presented with acute abdomen and intra-abdominal bleeding. This 24-year-old woman was previously diagnosed with a ruptured left ovarian cystic tumor at a primary clinic. She underwent emergency exploratory laparotomy, followed by unilateral salpingo-oophorectomy at the clinic. No thorough examination of the peritoneal cavity was done during surgery. The diagnosis of mucinous cystadenocarcinoma was accidentally over-looked until one month later when she returned for routine follow-up. Upon referral to our clinic, the patient underwent a repeat laparotomy. The surgicopathologic diagnosis was intraperitoneal carcinomatosis stage IIIC that could not be excised completely, even though rigorous staging surgery including washing cytology, total abdominal hysterectomy, salpingo-oophorectomy, retroperitoneal lymphadenectomy, appendectomy, infracolic omentectomy and excision of any suspicious and removable lesions were performed. This case alerts us to consider the possibility of ovarian malignancy when a young woman presents with an acute abdomen secondary to ruptured ovarian cystic tumor and intraperitoneal hemorrhage. Careful preoperative preparation and thorough intrasurgical examination of the peritoneal cavity along with a prompt pathologic diagnosis of suspicious lesions will prevent missed diagnoses.

7/255. Reversible paraneoplastic encephalomyelitis associated with a benign ovarian teratoma.

    BACKGROUND: Paraneoplastic encephalomyelitis (PEM) is a well characterized, and typically irreversible, paraneoplastic syndrome, usually associated with small cell lung cancer or other malignancy. We describe a case of a young woman with a benign ovarian teratoma who presented with a reversible PEM. CASE REPORT: A 24-year-old woman presented with a three week history of memory impairment, unusual behavior, personality changes, auditory hallucinations, hypersomnolence and binocular biplopia. On admission she was disoriented and inattentive with impaired short term memory. Small doses of lorazepam (1 mg), given for episodic agitation, repeatedly induced multidirectional bilateral nystagmus and a skew deviation, but her neurological examination was otherwise normal. A left-sided pelvic mass was palpable. brain MRI pre- and post-gadolinium was normal. There was a mild CSF pleocytosis and an EEG showed minimal bilateral background activity irregularities. There were no other laboratory abnormalities. Two weeks after admission, she clinically deteriorated developing central respiratory failure and a flaccid paraplegia. Repeat MRI showed an area of increased T2 weighted signal in the medulla and three similar areas in the spinal cord. Following removal of her tumor, treatment with high dose corticosteroids and intravenous immunoglobulin, she ultimately made a full recovery. pathology revealed the tumor to be a benign ovarian cystic teratoma. CONCLUSIONS: This is the first report of a reversible PEM seen in association with a benign tumor, in this case a mature ovarian teratoma. Presumably, an immune response directed against neural clements of the teratoma cross-reacted with normal brain, brainstem and spinal cord antigens to cause neurologic symptoms. Tumor removal was followed by neurologic recovery.

8/255. Malignant transformation of an ovarian mature cystic teratoma presenting as a rectal mass.

    BACKGROUND: Squamous cell carcinoma arising from malignant degeneration of a mature cystic teratoma is rare with a reported incidence of approximately 1-3%. The most common presenting symptoms are lower abdominal pain and increasing abdominal girth of several months' duration. Approximately 50% of the patients present with FIGO stage I while 35-38% present with stage III diseases. CASE: The case described herein represents an unusual presentation and initial diagnostic dilemma of locally aggressive squamous cell carcinoma arising in an ovarian dermoid cyst, with invasion into the distal rectum and anal canal causing rectal bleeding similar to the presentation of anal squamous cell carcinoma. Despite aggressive surgical management with posterior exenteration and optimal tumor debulking followed by 5040-cGy pelvic radiation utilizing 25-MV photons, the patient developed pelvic recurrence at the vaginal cuff 6 weeks after completion of her adjuvant radiotherapy. She subsequently failed cis-platinum single-agent chemotherapy and died 9 months after her initial surgery and diagnosis. CONCLUSION: Squamous cell carcinoma in the anal canal, diagnosed by colonoscopy or proctoscopy, could be an unusual presentation of that arising from malignant degeneration of an ovarian dermoid cyst. This tumor may behave in a locally aggressive manner and be resistant to pelvic radiation or single-agent chemotherapy of cis-platinum. The current experience of adjuvant treatment after comprehensive staging and cytoreductive surgery reported in the world literature is limited, and the optimal management of the malignancy remains unclear.

9/255. Endometrial adenocarcinoma with diffused/scattered "intramural" spreads: report of a case and review of the literature.

    A case is reported of endometrial adenocarcinoma of the uterus in an 85-year-old patient with an unusual spreading pattern. On macroscopic examination, only a tiny exophytic tumor was found in the uterine cavity, while microscopic examination demonstrated a scattered (scirrhous) spread of the carcinoma cells throughout the myometrium. The tumor occupied about half of the upper uterine corpus. The intramural spread of the tumor could not be seen at the time of macroscopic examination of the uterine cut surface. The tumor cells were attached closely to the serosal membrane, and metastasis to the left ovary was found. Intraoperative cytology detected malignant cells in the ascites. We present here this unusual type of endometrial carcinoma and review our previous report which dealt with pure "intramural carcinomas of the uterine corpus".

10/255. Transabdominal application of transvaginal transducer enhancing depiction of mature cystic teratoma at 34 weeks' gestation.

    We present an unusual case in which a 36-year-old patient was referred for consultation due to increasing upper left abdominal pain at 35 weeks' gestation. Transabdominal ultrasonography disclosed an appropriate-for-gestational-age singleton, vertex-presenting fetus with normal anatomy. An unclear, complex, semisolid, semicystic mass was noted in the upper right abdomen. Due to the close proximity of the adnexal mass to the patient's abdominal wall, a high-frequency transvaginal transducer was applied transabdominally. Unlike the unclear images generated at conventional transabdominal ultrasonography, this application depicted a discrete mass with multiple characteristics consisting of calcifications, hair and fatty tissue, considered diagnostic of a mature cystic ovarian teratoma. The patient delivered spontaneously at 39 weeks' gestation. At 6 weeks' postpartum an elective laparotomy left ovarian cystectomy was performed and a mature cystic teratoma confirmed by pathology examination.
