1/1144. Metastatic endometrial cancer in lung and liver: complete and prolonged response to hormonal therapy with progestins.

    A double complete and prolonged response of metastatic endometrial carcinoma to medroxyprogesterone is reported. A 61-year-old woman with metastatic endometrial carcinoma in lung and liver achieved a complete clinical response with medroxyprogesterone lasting for 2 years. She discontinued the therapy by herself and developed a pulmonary relapse, which disappeared after retreatment with the same hormonal therapy. At present, she is alive without evidence of disease 6 years after starting progestins for metastatic disease and 14 years after treatment of the primary tumor. Progestin therapy in metastatic endometrial carcinoma is discussed, emphasizing the factors predicting response.

2/1144. 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.

3/1144. An unusual cervical carcinoma showing exception to epitheliotropism of human papillomavirus.

    Human papillomaviruses (HPV) infect epithelial tissues but have not been previously detected within mesenchymal cells. During a systematic investigation of FIGO stage Ib cervical cancers with colorimetric in situ hybridization, we detected HPV 16 dna within the stromal compartment of an unusual undifferentiated carcinoma. The mesenchymal nature of the HPV-containing cells was confirmed by immunohistochemistry and electron microscopy. No viral particles were identified. Sequencing the majority of the HPV 16 genome identified few changes from the revised reference clone; all previously reported in other HPV 16 variants. These viral changes are unlikely to explain the exceptional mesenchymal localization of the HPV 16 dna in this case.

4/1144. Epithelial-myoepithelial carcinoma of the salivary gland--a low grade malignant neoplasm? Report of two cases and review of the literature.

    Epithelial-myoepithelial carcinomas (EMC) are rare neoplasms of the salivary gland with an incidence of less than 1% arising predominantly in the parotid gland. Although they are thought to be of low grade malignancy, fatal courses are described. We report a case of EMC of the parotid gland in a 58-year-old woman with an unfavorable course of this disease in long term follow-up. The malignant potential of this tumor is discussed. In addition, we include another case of EMC of the submandibular gland.

5/1144. Minute carcinoma of the pancreas measuring 1 cm or less in diameter--collective review of Japanese case reports.

    BACKGROUND/AIMS: According to Tsuchiya's collective review on small pancreatic cancer measuring 2 cm or less in diameter (5), more than half of them had obstructive jaundice and the 5-year survival rate was as low as 30%. Thus, a more aggressive diagnostic approach is needed to detect a smaller and more curable cancer of the pancreas. METHODOLOGY: Thus, we collected 36 reported cases of "minute" pancreatic cancer measuring 1 cm or less in diameter, from Japanese medical literature, to analyze the relationships between the diagnostic processes and long-term results. RESULTS: Excluding 3 patients with obstructive jaundice, the other 33 patients did not show any specific initial symptoms. However, 28 (78%) out of 36 patients showed an elevation in serum pancreatic enzyme levels and/or glucose intolerance. Among the 35 patients who had received ultrasonography (US) and/or computed tomography (CT), 20 (57%) patients showed duct dilation alone, whereas only 9 patients (26%) showed tumor mass. Among 35 patients who received an endoscopic retrograde pancreatography (ERP), all patients showed positive findings such as obstruction/stenosis, filling defect or duct dilation. All 36 patients underwent pancreatectomy and the 5-year survival rate was 57%. However, the 5-year survival rate was 34% in the 13 patients with jaundice and/or tumor mass depicted in US/CT, while it was 69% for the 22 patients without these two findings (p < 0.05). CONCLUSIONS: These data lead us to conclude that an elevation of serum pancreatic enzyme levels, glucose intolerance, and duct dilation alone depicted by US/CT should not be overlooked. ERP should be more widely applied to such patients, instead of persisting in delineating the tumor mass by US/CT or follow-up by tumor marker.

6/1144. Erosive adenomatosis of the nipple in an eight-year-old girl.

    Erosive adenomatosis of the nipple (EAN) is a rare, benign neoplasm of breast lactiferous ducts. Peak incidence is in the fifth decade in women. Clinically, it may be mistaken for Paget's disease and, histologically, for adenocarcinoma. Some authors have proposed an association with breast carcinoma and fibrocystic breast changes. Erosive adenomatosis of the nipple is extremely rare in children. Treatment is usually local excision of the nipple. This is the first formal English language case report of EAN in the pediatric age group. It is important for dermatologists to be familiar with this entity to prevent unwarranted breast removal.

7/1144. High-grade carcinoma component in epithelial-myoepithelial carcinoma of salivary glands clinicopathological, immunohistochemical and flow-cytometric study of three cases.

    Three cases of epithelial-myoepithelial carcinoma (EMC) with coexisting areas of high grade carcinoma are reported. In two of the cases there was a previous recurrence, and in all three patients there had been a sudden increase in size before final surgery. The typical ductal and myoepithelial components of EMC showed the usual biphasic pattern and the expected immunophenotypes, with expression of wide spectrum cytokeratins, Cam 5.2 and EMA in the ductal part, and muscle-specific actin, smooth muscle actin, S-100 protein, vimentin and cytokeratins in the myoepithelial component. These areas also had a low mitotic count and low proliferation rate as measured by immunohistochemistry and by flow cytometry. Conversely, areas of high-grade tumour had the features of a large cell carcinoma, with focal mucin secretion in two cases. This high-grade component showed an epithelial immunophenotype in two cases, and was negative for all tested markers in the third one. The mitotic counts and the proliferation rates were much higher in these anaplastic areas. One of the patients died 3 months after treatment; another developed lymph node metastases 1 year later and was alive after 6 years of follow-up. The third patient was alive without evidence of disease 7 months after wide surgical resection of the tumour. The possibility of anaplastic transformation in EMC makes thorough sampling mandatory in this type of neoplasm.

8/1144. A case of synchronous double primary lung cancer with neuroendocrine features.

    We report a case of unique double primary lung cancers with neuroendocrine features in a 63-year-old male smoker. The mass in the left lower lobe (LLL) was a small cell/large cell carcinoma with spindle cell sarcomatous areas and organoid structure. The mass in the left upper lobe (LUL) was a tubular adenocarcinoma with neuroendocrine features including organoid nests showing occasional rosette formation, nuclear palisading in the periphery of the nests and positive immunoreaction for CD56, chromogranin a and synaptophysin. The difference in histological structures between the two masses led us to diagnose double primary lung cancer. The combination of small cell lung carcinoma and spindle cell carcinoma is very uncommon. The relationship between LLL and LUL tumors remains unclear. Multiple lung cancers with neuroendocrine features have only rarely been reported in the literature. The patient in our case died of widespread cancer 2 years and 4 months after the surgery without adjuvant chemotherapy, a longer postoperative survival time than in cases of ordinary extensive small cell lung cancer. Multiple lung cancers with neuroendocrine features are extremely rare and similar cases have not been reported in the literature. Neuroendocrine differentiation has attracted widespread attention and, therefore, examining neuroendocrine features in lung cancers is important.

9/1144. Cancer-associated retinopathy in a patient with advanced epithelial ovarian carcinoma.

    BACKGROUND: Paraneoplastic phenomena, such as retinopathy, may herald an unsuspected gynecologic malignancy. CASE: A 75-year-old woman presented to a neuro-ophthalmologist with abrupt onset of unilateral visual loss. A diagnosis of branch retinal artery occlusion was made and she was treated with aspirin. An echocardiogram subsequently revealed atrial dilation and she was placed on coumadin therapy. Her vision worsened and a cancer-associated retinopathy was entertained. A serum cancer-associated retinopathy antibody was detected; subsequent computed tomographies of the abdomen and pelvis revealed findings consistent with a primary ovarian carcinoma. CONCLUSION: patients with unexplained ophthalmologic symptoms may harbor an underlying gynecologic cancer.

10/1144. Fractionated stereotactic radiation therapy for locally recurrent nasopharynx cancer: report of three cases.

    BACKGROUND: This article reports on experience with fractionated stereotactic radiation therapy (FSRT) for locally recurrent nasopharynx cancer. methods: Three patients with locally recurrent nasopharynx cancer were given FSRT as reirradiation between September 1995 and August 1996. Application of FSRT was the third radiation therapy in two patients. Authors used the individually made relocatable Gill-Thomas-Cosman (GTC) stereotactic frame, and the radiation dose planning was performed using XKnife-3. The total doses to the recurrent tumor were 45 Gy/18 fractions in two patients, who were given concurrent chemotherapy as a radiosensitizer, and 50 Gy/20 fractions in the other patient. In all three patients the dose per fraction was 2.5 Gy, and the fraction schedule was to give five daily treatments per week. RESULTS: Authors observed satisfactory symptomatic improvement and remarkable objective tumor size decrease through the magnetic resonance (MR) images taken one month post-FSRT in all three patients. No neurological side effect was observed. All three patients died with regional and distant seeding outside the FSRT field at seven, nine, and nine months, respectively. CONCLUSION: FSRT as reirradiation for locally recurrent nasopharynx cancer seemed to be effective and safe.
