11/733. Esophageal carcinoma showing a long stricture due to prominent lymphatic permeation: report of a case.

    Some esophageal diseases such as carcinoma, esophagitis, and collagen diseases have often been reported to show a diffusely thickened esophageal wall in the roentogenogram findings. In the current report, a preoperative upper gastrointestinal series and an endoscopic examination showed a diffusely infiltrative type carcinoma, but other examinations did not suggest any diseases such as esophagitis or collagen diseases which might cause a thickening of the esophageal wall or a constriction of the esophagus. A postoperative histological examination revealed the primary carcinoma to remain only within the mucosal layer, while a large degree of lymphatic vessel permeation reached the adventitia over a wide area. An extraordinary degree of lymphatic permeation spread through the esophageal wall, and stromal fibrosis developed as a result of such lymphatic permeation. These histological phenomena might thus have led to the macroscopic appearance of infiltrative type esophageal carcinoma.

13/733. paraneoplastic syndromes of leukocytosis, thrombocytosis, and hypercalcemia associated with squamous cell carcinoma.

    paraneoplastic syndromes including leukocytosis, thrombocytosis and hypercalcemia are occasionally seen in patients suffering from progressive malignant disorders. Recent studies have revealed the production of several humoral factors by tumor cells and normal splenic cells of tumor-bearing patients to be the major cause of these reactions. granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte-colony stimulating factor (G-CSF), parathyroid hormone-related peptide, interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF) have been implicated. We describe a 58-year-old Japanese man with squamous cell carcinoma (SCC) on the left sole, which developed in a deep linear scar after a train crash. He developed pulmonary and lymph node metastases, then leukocytosis (57,110/mm3 with 95% neutrophilia), thrombocytosis (86.3 x 10(4)/mm3), and hypercalcemia (7.0 mEq/1), and finally cachexia, followed by death. serum G-CSF, IL-1 alpha, IL-1 beta, and TNF-beta were determined; revealing G-CSF and IL-1 beta levels were above the upper limits of their normal ranges at 39.2 pg/ml and 4.63 pg/ml, respectively. It is probable that these humoral factors were partially responsible for the paraneoplastic syndromes induced by the cutaneous SCC with metastasis in the present case.

14/733. arsenic-related bowen's disease, palmar keratosis, and skin cancer.

    Chronic arsenical intoxication can still be found in environmental and industrial settings. Symptoms of chronic arsenic intoxication include general pigmentation or focal "raindrop" pigmentation of the skin and the appearance of hyperkeratosis of the palms of the hands and soles of the feet. In addition to arsenic-related skin diseases including keratosis, bowen's disease, basal-cell-carcinoma, and squamous-cell carcinoma, there is also an increased risk of some internal malignancies. arsenic-related diseases are common in areas of the world where the drinking water has a high arsenic content. In this paper, we describe a 35-year-old male patient who had arsenic-related keratosis, squamous-cell carcinoma in the palmar area of his left hand, and bowen's disease on his left thigh. The patient worked in a borax mine for 15 years, so he was exposed to arsenic in drinking water, airborne arsenic in his workplace, and had direct contact. The patient was treated for 11 months for arsenic-related keratosis until an axillary lymph node metastasis occurred; the lesion was excised and diagnosed to be malignant. bowen's disease was detected when the patient was being treated for cancer. No other malignancy was found. The patient is still receiving regular follow-up care.

15/733. Right intraventricular metastasis of squamous cell carcinoma of the uterine cervix: an autopsy case and literature review.

    An autopsy case of squamous cell carcinoma of the uterine cervix, which developed cardiac intracavitary metastasis in a 28-year-old Filipina, is reported. At autopsy, the right ventricle contained a soft, red-purple, cauliflower-like mass. Histologically, this mass was made up of sheets of malignant squamous cells similar to the primary uterine foci. The metastases were extensive and associated with multiple organ involvement. Although this case was stage Ib at operation, vascular invasion at the primary site was characteristic, and the intracavitary tumor of the right ventricle developed without myocardial involvement. The carcinoma of the primary site extended along the inferior vena cava and settled as an intracardiac obstructive mass. A literature review (including the present case) disclosed only 14 uterine cervical carcinomas with right intracavitary metastasis. The mean age of these patients was 46 years of age (range, 28-77 years). The clinical stage was Ib in two cases, IIa in one case, IIb in six cases, and IIIb in two cases. The prognosis of these cases was poor; 13 of the patients died at an average of 19.1 months after diagnosis.

16/733. The role of positron emission tomography in occult primary head and neck cancers.

    PURPOSE: To evaluate the utility of positron emission tomography (PET) fluorodeoxyglucose (FDG) imaging in the workup of unknown primary head and neck tumors. methods: Fourteen patients with squamous cell carcinoma of cervical lymph node metastasis of unknown primary origin (clinical stage N2-N3) were studied prospectively. The patients underwent conventional workup, including physical examination, computed tomography, and random biopsies of the potentially suspected sites. If no primary site was found, 8 to 13 mCi of FDG was given intravenously, and whole-body scans with standardized uptake values were obtained. The results of FDG-PET imaging were compared with clinical, CT, and histopathologic findings. To eliminate bias, PET scans were reviewed by nuclear medicine physicians who had no previous knowledge of the other findings. RESULTS: PET identified the location of primary tumor in three patients: lung hilum, base of tongue, and pyriform sinus. These lesions were pathologically confirmed. All these primary sites were not visualized on CT or physical examination, except for a pyriform sinus lesion, which was seen on CT, but initial biopsy result was negative. In one patient, the initial PET did not identify a primary tumor, but a nasopharyngeal carcinoma was identified in post-radiation therapy follow-up PET. In the remaining nine patients, a primary lesion was never found. All cervical lymph nodes detected by CT were identified by PET. DISCUSSION: A previously unknown primary tumor can be identified with FDG-PET in about 21% of the patients in our prospective series. PET can be of value in guiding endoscopic biopsies for histologic diagnosis and treatment options.

17/733. Cervical metastasis of occult papillary thyroid carcinoma associated with epidermoid carcinoma of the larynx.

    An occult, laterocervical papillary thyroid carcinoma tissue was found in a functional neck dissection for larynx cancer. The patient was a 76-year-old man with a history of smoking and alcohol ingestion who presented with a supraglottic carcinoma of the larynx located at the laryngeal surface of the epiglottis, left aryepiglottic fold, band and left ventricle with extension to the left vocal cord. light microscopy showed a lymph node with a fibrous stroma with lymphoid follicles that presented a total substitution of the parenchyma by a papillary thyroid carcinoma. Although examination of the thyroid gland by seriated sections did not reveal any neoplasm, we argue that the papillary thyroid tissue is metastatic.

18/733. Mediastinal lymph node involvement as the initial manifestation of occult thyroid cancer in the surgical treatment of lung cancer: report of a case.

    A 63-year-old man was referred to our institute for the treatment of squamous cell carcinoma of the upper lobe of his right lung. A right upper lobectomy of the lung was performed with a mediastinal lymph node dissection. The postoperative pathological examination of the dissected specimens revealed one of the superior mediastinal lymph nodes to be morbid with micrometastasis of occult thyroid cancer, while no node involvement was seen due to lung cancer. A right lobectomy of the thyroid gland with a modified radical neck dissection was done 4 years later after the confirmation of the absence of any recurrent sign of lung cancer. In the resected specimen, papillary thyroid microcarcinoma was observed with several intraglandular metastases and right regional lymph node involvement. Eight months later, a new primary lung cancer developed in the left lung, and a left upper lobectomy of the lung with a mediastinal lymph node dissection was performed. At that time, the absence of mediastinal lymph node metastasis from lung cancer or thyroid cancer was confirmed. Mediastinal lymph node involvement as the initial manifestation of occult thyroid cancer in surgical treatment for lung cancer is rare, but it is important to be aware of the possibility of incidentally detecting occult thyroid cancer in surgical dissections in this area for lung cancer. The appropriate surgical treatment should be determined while carefully considering the prognosis of the lung cancer as well as that of any coexisting malignancy.

19/733. Esophageal carcinoma with high serum parathyroid hormone-related protein (PTHrP) level.

    We report two patients with esophageal carcinoma with high levels of serum parathyroid hormone-related protein (PTHrP). Patient 1 was a 66-year-old man in whom the serum calcium level was also high, and patient 2 was an 81-year-old woman. The serum PTHrP level was 411 pM (normal range, 13.8-55.3pM) in patient 1 and 94.5 pM in patient 2 (in whom the serum granulocyte colony-stimulating factor level was also high). We demonstrated PTHrP immunohistologically in esophageal carcinoma cells in both patients. After admission, patient 1 died of pneumonia on the 17th day of hospitalization (the 48th day after he had had an episode of frequent hiccuping) and patient 2 died of acute circulatory failure on the 12th day of hospitalization (the 25th day after she had vomited after a meal). Neither of these patients died of cancer. pneumonia in patient 1 was believed to be due to weakened body defenses, while the acute circulatory failure in patient 2 was due to emaciation. Since esophageal carcinoma with humoral hypercalcemia of malignancy and leukocytosis is characterized by rapid progression and metastasis, early diagnosis and treatment are mandatory.

20/733. Acute lower extremity paralysis following radiation therapy for cervical cancer.

    BACKGROUND: Acute lower extremity paralysis secondary to lumbosacral plexopathy is a rare but severe complication that may follow pelvic radiotherapy for cervical cancer. CASE: A 49-year-old female with newly diagnosed stage IIIB cervical cancer developed progressive bilateral lower extremity paralysis and pelvic pain only 10 weeks following completion of radiation therapy for cervical cancer with no evidence of metastasis or progression of disease. Her bladder and bowel function were not affected. Following extensive workup, the most likely etiology was presumed radiation-induced lumbosacral plexopathy. CONCLUSION: Although metastatic carcinoma is more commonly the reason for progressive lower extremity weakness with pelvic pain in women with advanced cervical cancer, radiation-induced lumbosacral plexopathy, a rare but devastating complication, may be the cause. Diagnosis is by exclusion.
