11/3907. Middle ear adenocarcinoma with intracranial extension. Case report.

    Middle ear adenocarcinoma is a very rare, locally invasive neoplasm assumed to arise from the middle ear mucosa. Although endolymphatic sac tumor (aggressive papillary middle ear tumor) and jugulotympanic paraganglioma may show brain invasion, intracranial extension of histologically confirmed middle ear adenocarcinoma has not been previously reported. The authors describe a 53-year-old man who suffered from otalgia and tinnitus for more than 10 years and from neurological deficits for 1 year due to a large temporal bone tumor that invaded the temporal lobe. A combined neurosurgical and otolaryngological resection was performed. Pathological analysis revealed a low-grade adenocarcinoma of a mixed epithelial-neuroendocrine phenotype, which showed a close histological similarity to, and topographical relationship with, middle ear epithelium. The authors conclude that middle ear adenocarcinoma belongs to the spectrum of extracranial tumors that have possible local extension to the brain.

12/3907. Chemotherapy for advanced pancreatic cancer: it may no longer be ignored.

    Two case histories are reported here in which a chemotherapeutic approach improved the clinical conditions of patients with advanced pancreatic cancer. Until recently, chemotherapy was considered ineffective in pancreatic cancer, and most oncologists treated these patients with best-supportive-care only. Enthusiasm for systemic therapy of advanced pancreatic cancer is again growing, spurred by the advent of new drugs and new treatment endpoints such as life quality and symptom palliation. Gemcitabine, the most intensively-investigated new drug in pancreatic cancer, has shown an advantage in both survival and clinical benefit over that of 5-fluorouracil (5-FU). Other new drugs such as taxanes have shown interesting levels of activity, and are deserving of further evaluation. Although these results are far from conclusive and are only partially satisfactory, they represent a significant step forward in the treatment of advanced pancreatic cancer.

13/3907. Intrathoracic suture abscess after lobectomy for early lung cancer.

    Intrathoracic suture abscess may occur around sutures on the pleura or in the lung parenchyma, although it is rare to encounter such cases clinically. We report on a 68-year-old woman with an intrathoracic (extrapulmonary) suture abscess, which was discovered on a chest x-ray film one year after right-middle lobectomy for early lung cancer. The abscess was removed surgically, and the postoperative course was uneventful. Pathological examination showed that it was caused by braided polyester sutures.

14/3907. Synchronous and metachronous gastric adenocarcinoma: case report and literature review.

    Whilst synchronous adenocarcinoma of the stomach is well documented, metachronous primary disease is exceedingly rare. We report a man with a family history of colonic and gastric cancer, who underwent a resection of a Duke's C adenocarcinoma of the rectum, aged 56 years, and a proximal partial gastrectomy for synchronous stage 1 gastric adenocarcinomas of the lesser curve, aged 61 years. Nine years later, a metachronous gastric primary was discovered in the gastric remnant, necessitating total gastrectomy. Total gastrectomy is the operation of choice for synchronous gastric primaries as it ensures clearance and prevents metachronous growth. However, it may not be appropriate for all gastric cancer as operative morbidity and mortality are increased, and because synchronicity and metachronicity of gastric cancer are uncommon. Moreover, there are no consistent data to demonstrate a survival advantage for total compared with partial gastrectomy for operable gastric cancer. If, after partial gastrectomy, synchronous disease is detected in the resected specimen (as in this reported case), endoscopic surveillance for metachronous disease is advised, since this may be amenable to surgical cure.

15/3907. Cytologic diagnosis of metastatic ovarian adenocarcinoma in the urinary bladder: a case report and review of the literature.

    A 53-yr-old woman with a 13-mo history of recurrent ovarian papillary serous adenocarcinoma presented with persistent microscopic hematuria. The patient was undergoing chemotherapy for her recurrent ovarian tumor when she was referred to the urology service for microscopic hematuria. An intravenous pyelogram was normal. cystoscopy was performed, as well as a urinary bladder washing and mucosal biopsies for examination. adenocarcinoma similar to the patient's primary ovarian tumor was detected in both cytology and histopathology specimens. Ovarian carcinoma comprises 1.3-4.0% of all metastatic neoplasms to the urinary bladder and is an important consideration in the differential diagnosis of a cytologic finding of adenocarcinoma in urine specimens of female patients, where it accounts for an even higher percentage of cases (1 of 3 adenocarcinoma diagnoses in a series of 4,677 urine specimens from female patients).

16/3907. learning from case reports: diagnostic issues in an epidemiologic study of pancreatic cancer.

    epidemiologic studies on exocrine pancreatic cancer show a large heterogeneity in diagnostic criteria applied to define "caseness." Reanalyses conducted after review of diagnostic information have yielded substantially different results than those based on more crude classifications of disease. During a multicenter prospective study on mutations in the K-ras gene in pancreatic and biliary diseases, hospital diagnoses from 602 patients were reviewed by a panel of experts. There were two main motivations to do so: a generic interest for the quality of the diagnostic data, and the anticipation that a firm diagnosis could be needed to assess whether patients whose tumors did not harbor the mutation were true negatives or false negatives. In addition, the review of diagnoses was helpful to minimize tissue misclassification, and it had a high educational value for clinicians and epidemiologists. This article illustrates why and how this was so through a brief presentation of the 10 most significant cases. With respect to selection and classification of subjects, the main issues that studies on pancreatic cancer need to address are the differential diagnosis of exocrine pancreatic cancer and pancreatitis, the differential diagnosis of exocrine pancreatic cancer and other abdominal tumors, and the use of survival as a hallmark of pancreatic cancer. In epidemiologic studies of pancreatic cancer, it is warranted that a panel of experts centrally reviews all the existing diagnostic evidence (cytohistological and other) of all patients, regardless of whether they have cytohistological confirmation and of their hospital discharge diagnosis.

17/3907. A case of chordoma in association with rectal carcinoma.

    A 74-year-old male patient presented with anal and sacral pain 18 months after abdomino-perineal resection for rectal cancer. Computerized tomography (CT) of the pelvis demonstrated a well defined mass anterior to the lower sacrum, posteriorly infiltrating and destroying the fourth and fifth sacral nerves and invading the right gluteal fossa. A 7.5 x 15 x 2 cm encapsulated mass was demonstrated during the operation using a posterior approach and the lower sacral segments together with the tumour were removed by amputation at S3 level. Histopathology revealed chordoma. This case is unique because of the rarity of chordoma in association with rectal tumour at the sacrococcygeal region.

18/3907. Primary breast carcinoma of the vulva: a case report and literature review.

    BACKGROUND: In 1872, Hartung was the first to describe the case of a fully formed mammary gland arising in the left labium majora of a 30-year-old woman. Since Hartung's initial report, 38 additional cases of ectopic vulvar breast tissue have been described. This case report describes the rare occurrence of primary mammary adenocarcinoma arising within the vulva. CASE: A 64-year-old G4P4 white female presented with a 4-year history of a 2 x 1 cm firm, indurated, raised lesion of the left lateral mons. A wide local excision with ipsilateral inguinofemoral lymphadenectomy was performed. Given histological findings characteristic of both invasive ductal carcinoma and invasive lobular carcinoma, in conjunction with the presence of estrogen and progesterone receptors within the tumor, a diagnosis of infiltrating adenocarcinoma arising within ectopic breast tissue was made. CONCLUSIONS: Thirty-nine reported cases of ectopic breast tissue arising within the vulva have been reported in the world literature. Though the diagnosis of primary breast carcinoma arising within the vulva is based primarily upon histologic pattern, estrogen and progesterone receptor positivity provide supporting evidence. Given the rarity of this condition, guidelines for therapy are unavailable; we therefore suggest looking to the current management of breast cancer in order to establish a sensible approach.

19/3907. The ultrastructure of a poorly differentiated adenocarcinoma of the human tuba uterina.

    A poorly differentiated adenocarcinoma of the human oviduct was studied by light and transmission electron microscopy. cells contained abundant mitochondria, bound and free ribosomes, prominent Golgi's bodies and aggregates of membrane-bound dense bodies. The small glandular lumina with numerous microvilli were generally devoid of cilia and contained secretory material. The neoplasm was ultrastructurally similar to poorly differentiated ovarian serous carcinomas.

20/3907. Quadruple cancer including bilateral breasts, Vater's papilla, and urinary bladder: report of a case.

    We herein report a rare case of quadruple carcinoma with heterochronous bilateral breast cancer, cancer of Vater's papilla, and cancer of the urinary bladder, which were all curatively resected. A 62-year-old woman previously underwent right and left modified radical mastectomies heterochronously. Recently, a dilatation of the lower bile duct, diagnosed as cancer of Vater's papilla, was resected by a pancreatoduodenectomy. hematuria during surgery led to the discovery of a solid bladder tumor. The tumor was resected by a transurethral resection. The histopathologic findings differed for all four lesions. The patient had an uneventful postoperative course and to date has shown no recurrence.
