1/425. Adrenal cancer with hypertension but low plasma renin and aldosterone.

    patients with malignant lesions of the adrenal gland may present with a syndrome of excess mineralocorticoids. Both primary hyperaldosteronism and excess mineralocorticoids other than aldosterone resulting from adrenal carcinoma have rarely been reported. In most patients with adrenal tumors secreting mineralocorticoids other than aldosterone, distant metastasis had already occurred at the time of diagnosis and the prognosis was poor. We present a rare case of adrenal cancer with hypertension in a patient with low plasma renin activity and a low plasma aldosterone concentration. The patient's blood pressure returned to normal after removal of the tumor. The patient is still alive and without recurrence 6 years after surgery. This case illustrates the value of thorough evaluation of hypertension and prompt surgical treatment for patients with adrenal cancer.

2/425. Prolonged lactic acidosis after extended hepatectomy under in situ hypothermic perfusion.

    A 46-year-old woman underwent right extended hepatectomy under total vascular occlusion with in situ hypothermic perfusion for colorectal metastasis. Immediately after surgery, she developed severe lactic acidosis, which required correction with sodium bicarbonate solution and ventilatory support for 36 hours. After 2 days, her lactate normalized, and the acidosis was corrected. She made an uneventful recovery. Persistent lactic acidosis after major hepatic resection under in situ hypothermic perfusion is a rare but reversible problem.

3/425. Progression of a Nelson's adenoma to pituitary carcinoma; a case report and review of the literature.

    A 25-year-old woman developed Nelson's syndrome, 3 years after successful bilateral adrenalectomy for Cushing's disease. Despite pituitary surgery and radiotherapy the tumour showed invasive growth, leading to visual disturbance, paresis of the oculomotor nerve and, 34 years after adrenalectomy, to death by widespread purulent leptomeningitis. autopsy revealed a large adenohypophyseal carcinoma with a metastasis attached to the dura, both tumours showing immunocytochemical staining for ACTH and TSH. We review the literature on metastatic adenohypophyseal carcinoma in Cushing's disease and Nelson's syndrome and discuss the role of proliferation markers as indicators of malignant progression.

4/425. Parasitic nodule of the thyroid in a patient with Graves' disease.

    We report a case of a parasitic nodule of the thyroid in a patient with Graves' disease, which mimicked a lymph node metastasis from a primary occult thyroid carcinoma. The patient was a 67-year-old Japanese woman with a past history of subtotal thyroidectomy for Graves' disease, who was referred to our hospital because of a right cervical mass. A lymph node-like lesion measuring 1.5 cm in diameter was palpable, distinct from the remnant of the right thyroid lobe. Thyroid scintigraphy using 123I-Na revealed a hot lesion at the upper lateral portion of the right thyroid lobe, and this was resected. Microscopically, the mass showed thyroid follicles with lymphocytic infiltration and lymphoid follicles. Clear ground glass nuclei, nuclear grooving and intranuclear inclusions were not observed. No morphological evidence of the lymph node was found in the mass by reticulin staining. Parasitic nodules of the thyroid in patients with Graves' disease may mimic a metastatic carcinoma of the thyroid.

5/425. Pituitary metastasis from carcinoma of the urinary bladder mimicking pituitary apoplexy--case report.

    A 70-year-old male presented with pituitary metastasis from transitional cell carcinoma of the urinary bladder manifesting as sudden headache, transient unconsciousness, and visual disturbance mimicking apoplexy of pituitary adenoma. Computed tomography showed a suprasellar tumor with intratumoral and intraventricular hemorrhage. magnetic resonance imaging demonstrated an intra- and suprasellar mass lesion mimicking pituitary adenoma. diabetes insipidus developed soon after. The tumor was subtotally removed. Histological examination revealed transitional cell carcinoma. An intratumoral hemorrhage may be associated with a pituitary metastasis if the patient presents with symptoms such as pituitary apoplexy.

6/425. Epithelial-myoepithelial carcinoma arising in the nasal cavity: a case report and review of literature.

    Epithelial-myoepithelial carcinoma is an uncommon, low-grade, malignant epithelial neoplasm composed of variable proportions of ductular cells and large, clear staining, myoepithelial cells arranged around the periphery of the ducts. About 120 cases have been reported in the world literature, most of which were located in salivary glands, except for a few cases occurring in unusual locations such as breast, lacrimal gland, nose, paranasal sinus, trachea, bronchus, and lung. We here reported the second case of epithelial-myoepithelial carcinoma of the nasal cavity with extension to the nasopharynx. The patient was a 61 year old Chinese female with two month's history of progressive nasal obstruction. Histopathologically, the tumor showed typical myoepithelial and ductal cells biphasic differentiation, duct-like structure and infiltrating growth pattern. Some ductal cells showed the characteristics of oxyphilic cell, which had never been reported before. recurrence and metastasis rates of epithelial-myoepithelial carcinoma varied from 35% to 50% and 8.1% to 25% respectively in different reports. The present case had neither recurrence nor metastasis twenty months after operation. When epithelial-myoepithelial carcinoma is mainly composed of spindle myoepithelial cells, the differential diagnosis should include myoepithelioma, neurofibroma, leiomyoma and hemangiopericytoma.

7/425. Acute subdural hematoma and pachymeningitis carcinomatosa: case report.

    Subdural hematomas may affect 0.4-5 p. 100 of patients with cancer, because of predisposing risk factors or because of the cancer itself. The most likely association is with hematological cancer with coagulative disorders. An association with pachymeningitis carcinomatosa is less likely. In this instance the subdural hematoma is due to a neoplastic obstruction of dural vein with subdural engorgement and hemorrhage or subdural effusion. We report a case in which an acute neurological deterioration due to a subdural hematoma disclosed a dural metastasis from a breast cancer operated four years earlier and present a literature review.

8/425. A patient with brain metastasis from ovarian cancer who showed complete remission after multidisciplinary treatment.

    We describe a case with brain metastasis from ovarian cancer who showed complete remission after multidisciplinary treatment. The case was diagnosed as epithelial ovarian cancer, FIGO stage IIIc. She underwent cisplatin-based chemotherapy after optimal cytoreductive surgery and achieved clinical complete remission. Thirty-two months after surgery for ovarian cancer, a solitary metastasis occurred in the left frontal lobe of the brain. No recurrent lesions were observed outside the brain. The metastatic tumor was resected. Five days after operation, adjuvant chemotherapy comprising carboplatin and cisplatin was initiated (a total of three courses at 4-week intervals), and whole brain irradiation at 55 Gy was added. After these treatment methods, complete remission of the brain metastasis has been observed for 57 months with good quality of life.

9/425. Metastatic salivary duct carcinoma to the uterus: report of a case diagnosed by cervical smear.

    Metastasis to the uterus from extragenital sites is uncommon. We report on a rare case of salivary duct carcinoma (SDC) of the parotid gland with metastasis to the uterus, diagnosed by cervical smear. To the best of our knowledge, this is the first case reported in the literature. A 61-yr-old woman with a prior diagnosis of SDC was admitted to hospital with a fractured left humerus, back pain, and vaginal bleeding. A cervical smear and an endometrial aspiration were performed. The cervical smear showed numerous fragments and many isolated tumor cells in a clean background. The tumor cells were large and had abundant, granular/vacuolated cytoplasm. The nuclei were slightly pleomorphic, with fine chromatin and 1-2 small nucleoli. The malignant cells were morphologically identical to the primary tumor and correlated with the tumor in the endometrial aspiration. A diagnosis of metastatic salivary duct carcinoma was made. Although metastatic SDC to the uterus is rare, this possibility should be considered in the differential diagnosis of a positive cervical smear. This case also illustrates the importance of appropriate clinical history, including the knowledge of a primary tumor which may prevent unnecessary clinical investigations. Diagn. Cytopathol. 1999;21:271-275.

10/425. Adoptive therapy of canine metastatic mammary carcinoma with the human MHC non-restricted cytotoxic T-cell line TALL-104.

    adoptive transfer of human TALL-104 killer cells into a dog with metastatic mammary adenocarcinoma resulted in 50% reduction of the largest lung metastasis and stabilization of the other lesions for 10 weeks, accompanied by the development of tumor-specific immune responses. Upon halting cell therapy, the dog developed new lung lesions within 10 weeks and died of slowly progressive disease. TALL-104 cell therapy of mice bearing the dog's tumor xenograft induced 65% reduction of local tumor growth and regression of lung metastases in 100% of the animals. The overall findings indicate the therapeutic potential of TALL-104 cells for canine mammary tumors.
