1/505. False-positive result of a total-body scan caused by benign thyroidal tissue after I-131 ablation.

    This case report illustrates a false-positive result of an I-131 total-body scan caused by abnormal, noncancerous thyroid tissue. A 39-year-old woman underwent an open biopsy and thyroidectomy for a papillary thyroid carcinoma. She was treated by ablation with 150.8 mCi I-131. A follow-up total-body scan revealed a solitary focus of increased activity near the midline at the upper border of the larynx that was subsequently excised. Histologic analysis indicated a fragment of thyroid tissue with chronic inflammation, fibrosis, and squamous metaplasia. No evidence of thyroid carcinoma was present. Hypofunctioning or nonfunctioning residual tissue within the thyroglossal duct may have been suppressed under euthyroid conditions, protecting it from ablation. This tissue may have become stimulated by the high thyroid-stimulating hormone levels, accumulating I-131 and producing a false-positive result of the scan.

2/505. Tall cell variant of papillary thyroid carcinoma with foci of columnar cell component.

    We report a case of the tall call variant of papillary thyroid carcinoma with foci of columnar cell component in a 67-year-old Japanese man. Tall cell variant occupied more than 70% of the tumour, and columnar cell component was of two types in representative sections. One showed striking stratification of nuclei with scanty cytoplasm, and the other appeared clear. Characteristic nuclear features of papillary carcinoma were also observed in the area of the tall cell variant. The patient died of the thyroid cancer with aspiration pneumonia 10 years and 6 months after operation. Although autopsy was not performed, metastatic lymph nodes of the neck removed during life also showed papillary carcinoma with both tall cell and columnar cell components. Our case indicates that tall cell and columnar cell variants may coexist in the same tumour although the pathogenesis remains unclear.

3/505. Tall cell variant of papillary thyroid cancer.

    Papillary histologic type is the most common form of thyroid carcinoma amounting to 85% cases. This pathology presents a rather good prognosis, but a few years ago, new subtypes have been described. Some of these variants show a fairly good prognosis i.e follicular, macropapillary, encapsulated while others appear to have a decidedly worse one, columnar cells, diffused sclerosing, or even to be clearly malignant as in the case of the tall cell variant. The authors report a case treated by a combined surgical and radiometabolic therapy and evidence the main characteristics of this rare and underestimated neoplasia.

4/505. Papillary transitional cell carcinoma of the breast: a report of five cases with distinction from eccrine acrospiroma.

    Papillary carcinomas of the female breast exhibit a spectrum of morphologic appearances and might be mistaken for benign intraductal papillary lesions or papillary adnexal neoplasms. We report herein five cases of papillary carcinoma in which the epithelium closely resembled transitional cells of the urinary bladder. Grossly, the tumors had a nodular or papillary appearance, white, tan, or red in color. The microscopic features were those of an intraductal papillary proliferation of solid layers of epithelial cells overlying fibrovascular cores. The proliferating cells assumed a whorled or streaming growth pattern, with flattening of superficial cells. One case showed microinvasion. Comparison with a similar number of cases of the solid variant of papillary carcinoma of the breast showed a greater range of nuclear pleomorphism, mitotic counts, and a more varied immunohistochemical profile in the papillary carcinomas with transitional cell features. Eight cases of eccrine acrospiroma occurring in the female breast also displayed a solid or solid papillary pattern, with flattened superficial cells. These occurred in a younger age group, were located in the dermis or subcutis, and usually had zones of clear cells visible at low magnification. No evidence of recurrent or metastatic disease was found in the four patients for whom follow-up was available; the length of follow-up ranged from 18 months to 11 years. The stimulus for the development of this unusual phenotype is unclear, but the transitional-like variant seems to behave in a fashion similar to that of other types of papillary carcinoma of the breast. Distinction of this malignant lesion from various benign lesions that occur in the same region is mandatory.

6/505. Elevated reticulocyte count--a clue to the diagnosis of haemolytic-uraemic syndrome (HUS) associated with gemcitabine therapy for metastatic duodenal papillary carcinoma: a case report.

    In adults, the haemolytic-uraemic syndrome (HUS) is associated with probable causative factors in the minority of all cases. Cytotoxic drugs are one of these potential causative agents. Although metastatic cancer by itself is a recognized risk-factor for the development of HUS, therapy with mitomycin-C, with cis-platinum, and with bleomycin carries a significant, albeit extremely small, risk for the development of HUS, compared with all other cytotoxic drugs. Gemcitabine is a novel cytotoxic drug with promising activity against pancreatic adenocarcinoma. We are reporting on one patient with metastatic duodenal papillary carcinoma developing HUS while on weekly gemcitabine therapy. The presenting features in this patient were non-cardiac pulmonary oedema, renal failure, thrombocytopenia and haemolytic anaemia. The diagnosis of HUS was made on the day of admission of the patient to this institution. Upon aggressive therapy, including one single haemodialysis and five plasmaphereses, the patient recovered uneventfully, with modestly elevated creatinine-values as a remnant of the acute illness. Re-exposure to gemcitabine 6 months after the episode of HUS instituted for progressive carcinoma, thus far has not caused another episode of HUS.

7/505. 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.

8/505. Successful surgical treatment of a solitary parapharyngeal metastasis from thyroid cancer, using the mandibular swing-transcervical approach: report of a case.

    A 72-year-old man presented with a right parapharyngeal mass, 4 cm in diameter, which was subsequently diagnosed as a metastasis originating from papillary carcinoma of the thyroid gland. The parapharyngeal tumor was successfully removed by the mandibular swing-transcervical approach with pharyngeal reconstruction, performed using a buccal mucosal island flap based on the facial artery. His postoperative course was uneventful, and the preoperative clinical symptoms such as dysphagia and headaches completely resolved after surgery.

9/505. Thyroid lung metastasis diagnosed 47 years after thyroidectomy.

    A 75-year-old woman underwent excision of a middle lobe lung nodule that contained a separate, isolated focus of metastatic papillary thyroid carcinoma. A thyroid lobectomy for papillary cancer had been performed 47 years earlier. This interval is believed to be the longest time from initial diagnosis to identification of distant lung metastasis reported. The pertinent published reports are reviewed and methods of surveillance discussed.

10/505. radiation myelopathy with partial functional recovery: PET evidence of long-term increased metabolic activity of the spinal cord.

    Postoperative telecobalt irradiation was performed with a biologically effective extrapolated response dose of 165 Gy2 delivered to the spinal cord of a papillary thyroid cancer patient. Incomplete cervical transection developed, followed by a gradual functional improvement, which is still continuing 8 years after radiotherapy. Between the 6th and 8th years of the clinical course, positron emission tomography investigations demonstrated an increased 18F-deoxyglucose accumulation and (15)O-butanol perfusion, but negligible 11C-methionine uptake in the irradiated spinal cord segment. We suggest that the increased metabolism and perfusion, and the lack of detectable protein synthesis may be related to the increased energy demands of action potential conduction, due to the higher than normal density of sodium channels along demyelinated axons displaying restored conduction.
