1/3084. Clinical value of protein-bound fucose in patients with carcinoma and other diseases.

    Protein-bound fucose content in sera from normal persons and patients with various malignant and non-malignant diseases was measured and statistically analyzed. Normal serum gave a mean value of 6.84 /- 0.13 mg/100 ml, and rarely exceeded 9 mg/100 ml. Although no significant difference was found between sexes, there was a tendency of fucose content to decrease in older persons. It was noted that more than 90% of cancer-bearing patients have significantly higher level than critical value (9 mg/100 ml), while only 8.7% of patients with benign tumor showed positive result. These results were not limited to special organs but in common to all cases studied. The elevation of serum fucose content in malignant tumor was well correlated with its stages of progression, though the levels were less significant in early and in rather locally restricted breast and thyroid cancer. Serial postoperative follow-up study showed that the levels in serum fucose content was a useful parameter for judging the effectiveness of therapy and the prognosis of the patient. The fucose content in malignant tumor tissue and metastasized lymph node appeared to be significantly elevated than that in normal tissue. The practical usage and limitation of the fucose value in various diseases, together with a possible source of serum fucose were discussed. ( info)

2/3084. Small cell neuroendocrine carcinoma of the cervix with involvement of multiple pelvic nodes--A successfully treated case by multimodal approach.

    Small cell neuroendocrine carcinoma of the cervix is very rare and is usually associated with dismal prognosis if treated by conventional surgery and radiotherapy even in early stage disease. This tumor is characterized by early lymphatic and hematogenous spread. Only one successfully treated case of small cell neuroendocrine carcinoma of the cervix with dissemination to the pelvic nodes had been reported before in the literature. We are reporting a case of small cell neuroendocrine carcinoma of the cervix with multiple pelvic nodal metastases including the common iliac nodes, which had been successfully treated with a multimodal approach including radical hysterectomy, pelvic/para-aortic lymphadenectomy, and postoperative chemotherapy using cisplatin-etoposide combinations and pelvic irradiation.

3/3084. Acinic cell carcinoma of the lung with metastasis to lymph nodes.

    A 64-year-old man presented with an asymptomatic left lower lobe mass. At bronchoscopy there was a tumor in the superior segment. biopsy revealed an acinic cell carcinoma. There was no evidence of salivary gland or other site of origin. Lobectomy and lymph node staging showed involvement of interlobar (N1) nodes, while higher stations were benign. The patient remains well 20 months postoperatively. This is the only instance of primary pulmonary acinic cell carcinoma with lymph node metastasis among 15 cases in the literature. We review the clinical features, histology, and treatment of the reported cases. ( info)

4/3084. melanosis in association with metastatic malignant melanoma: report of a case and a unifying concept of pathogenesis.

    An unusual case of melanosis associated with metastatic malignant melanoma is reported. This was characterized by progressive blue/gray discoloration of the skin of the chest and abdomen in an elderly patient, 1 year after removal of a polypoid malignant melanoma from the right arm. A biopsy of involved skin revealed perivascular aggregates of melanin-laden histiocytes throughout the dermis, the histopathologic hallmark of melanosis. An unusual aspect of the case was the coincidental finding of a tumor embolus within a small dermal vessel, probably a lymphatic. To date, neoplastic melanocytes have been detected in only a small minority of skin biopsies with features of melanosis. This case and a distillation of related information in the literature lead to the conclusion that the essence of melanosis, and the feature that distinguishes this from conventional metastatic melanoma, is the persistent and cumulative dissemination of melanin, via the bloodstream, throughout the body. This in turn leads to progressive pigmentation of all internal organs and the skin. Only continuous access to the circulation by neoplastic melanocytes could explain such a phenomenon. Potential mechanisms by which this could arise are discussed in the context of existing knowledge. ( info)

5/3084. carcinoma of the colon in children: a report of six new cases and a review of the literature.

    Of six children with carcinoma of the colon, none had ulcerative colitis or a family history of carcinoma of the colon or colonic polyposis. In 75 cases traced in the literature, a common early symptom of carcinoma of the colon in children is acute, crampy abdominal pain. At laparotomy for suspected appendictis, the possibility of the acute pain being due to carcinoma of the colon should be borne in mind. Otherwise the symptoms of carcinoma of the colon in children do not differ substantially from those in adults. The prognosis is unfavorable; in only 2.5% of the cases on record did the children survive 5 yr after the operation. ( info)

6/3084. Benign renal angiomyolipoma with regional lymph node involvement.

    The 2 cases reported herein involve benign renal angiomyolipomas, showing the same angiomyolipoma changes in the regional lymph nodes. It is concluded that these lymph node changes are caused by a multicentric origin of the angiomyolipoma rather than true metastasis. A plea is made not to over treat these tumors since all evidence points to the fact that they are indeed benign. ( info)

7/3084. Axillary metastases of an occult primary carcinoma of the breast-discovered only by 99mTc-tetrofosmin scintigraphy.

    Recent reports consider 99mTc-tetrofosmin scintigraphy to be a powerful new diagnostic tool for discriminating malignant from benign breast disease. We report on a woman suffering from histologically confirmed axillary metastases of a primary unknown, occult carcinoma, whose origin was suspected within the breast. All the diagnostic procedures performed to discover any lesion failed or were inconclusive. The primary cancer was clearly visualized, however, in the right breast by means of 99mTc-tetrofosmin scintigraphy. Conclusion. We suggest that 99mTc-tetrofosmin scintigraphy is a powerful method to detect breast cancer, especially when other diagnostic imaging procedures are inconclusive. ( info)

8/3084. Malignant mixed mesodermal tumor presenting as metastatic lymph node adenosquamous cell carcinoma: a case report.

    A solitary inguinal lymph node metastasis from a poorly differentiated adenosquamous cell carcinoma of unknown origin in a 52-year-old female is described. The patient was reported to have had a 2-cm palpable mass in the left inguinal area for three years. She had made regular annual clinic visits for Pap smears since the age of 45 years. Her last visit was eight months prior to a complaint of progressive abdominal distention and dull pain of three months' duration. physical examination showed a huge pelvic mass, and ultrasound and magnetic resonance imaging of the abdomen showed a 12-cm complex solid mass on the left ovary. The patient underwent a complete excisional biopsy of the left inguinal lymph node. Frozen section pathology revealed a poorly differentiated adenosquamous cell carcinoma. Exploratory laparotomy immediately followed pathologic confirmation of malignancy of the left inguinal lymph node. Complete surgical staging including abdominal cytology, total abdominal hysterectomy, bilateral salpingo-oophorectomy, infracolic omentectomy, retroperitoneal lymph node sampling and excisional biopsy was performed for all suspicious lesions. Stage IIIC malignant mixed mesodermal tumor (MMMT) was diagnosed due to positive left inguinal lymph node metastasis. However, the retroperitoneal lymph node and intra-abdominal cavity did not show spread of the tumors, except those confined to the left ovary with adhesion to the cul-de-sac, and sole lymph node metastasis in a left inguinal lymph node. Although we could not prove that the left inguinal lymph node metastasis had been present for the three years that it was palpable without histologic confirmation, we believe that any enlarged inguinal lymph node might be the first hint of underlying malignancy in the pelvic area, lower extremities or perineal area. In cases of a poorly differentiated carcinoma of inguinal lymph nodes of unknown origin, the abdomen should be carefully evaluated. ( info)

9/3084. p53 gene mutation in 150 dissected lymph nodes in a patient with esophageal cancer.

    For thoracic esophageal cancer, we perform extended three field lymph node dissection, and have achieved nearly 50% of overall 5-year survival. However, patients sometimes develop lymph node recurrences in spite of having no lymph node metastases found by conventional histopathologic examination. In a patient with esophageal squamous cell carcinoma, we sequenced all the p53 cDNA translated regions (exon 2-10) of primary carcinoma, and confirmed one p53 nonsense mutation in exon 10. Then we extracted genomic dna from 150 surgically dissected lymph nodes from that patient, and performed polymerase chain reaction analysis (PCR-RFLP) to detect the same p53 mutation in the lymph nodes. PCR-RFLP analysis showed the same p53 mutation in six lymph nodes. One node was located along the right recurrent laryngeal nerve, where no positive nodes was identified by conventional histopathologic examination. The p53 mutational diagnosis of metastatic cancer may be useful in detecting minimal residual disease. ( info)

10/3084. A pathologic and clinical study of adenosquamous carcinoma of the larynx. Report of four cases and review of the literature.

    Four cases of adenosquamous carcinoma are described. Emphasis is put on the rarity of this histological type of tumour which was first described in the larynx by Gerughty et al. (1968) who reported three cases. An exhaustive histological documentation of the neoplasm accompanies the discussion of its pathomorphological characteristics, histogenesis, differential diagnosis, prognosis and treatment. Stress is laid on the extreme aggressiveness of the neoplasm and on its high biologic malignancy. Elective treatment is radical surgery. The tumour in question is a distinct anatomo-clinical entity with its own connotations and therefore must be distinguished from the most common squamous cell carcinoma of the larynx. ( info)
