    Notes: Abstract Accessory bile duct with ectopic drainage into the gastrointestinal tract is an extremely rare congenital anomaly, and only 55 cases have been reported in the literature. We present another case of accessory bile duct draining into the stomach. Barium meal study of the stomach first revealed the accessory bile duct, and the diagnosis was confirmed by gastrofiberscopy, ultrasonography, hepatobiliary scintigraphy, computed tomography (CT), and endoscopic retrograde cholangiopancreatography (ERCP).

    Distribution of cellular carbohydrate moieties in human dysontogenetic brain tumors, especially in craniopharyngioma and epidermoid/dermoid (1992)

    Notes: Summary Cellular carbohydrate moieties of 65 human dysontogenetic brain tumors (craniopharyngioma, epidermoid/dermoid, Rathke cleft cyst, germinoma and non-germinomatous germ-cell tumors) and 60 common brain tumors (glioma, meningioma, neurinoma and pituitary adenoma) were investigated histochemically using lections from Ulex europaeus (UEA-1), Dolichos biflorus (DBA), peanut (PNA) and soybean (SBA), and with anti-blood group A and LewisY (LeyY) antibodies. In craniopharyngiomas and epidermoid/dermoids, it was found that PNA and SBA binding sites existed in suprabasal cells of the epithelium, and that antigen of either blood group A or H (demonstrable by UEA-1) existed in more differentiated epithelial cells compared to the results reported in normal human skin epidermis. Rathke cleft cysts were stained with PNA or SBA, and two out of three Rathke cleft cysts also expressed either H or A antigen. In addition, DBA binding sites, as well as LeY antigen, were frequently seen in craniopharyngiomas and Rathke cleft cysts, but they were entirely absent in the epithelium of epidermoid/dermoid. On the other hand, PNA and SBA reactivities was also found in common brain tumors, while blood group A, H and LeY antigens and DBA reactivity were almost absent in these tumors. These findings demonstrate that carbohydrate moieties such as those of blood group antigens reported to be found in human skin epidermis exist in a similar form in craniopharyngioma, epidermoid/dermoid and the Rathke cleft cyst. The identification of blood group A, H and LeY antigens and DBA reactivity in brain tumors seems to be considerably limited and specific. Thus, carbohydrate antigen reacting with DBA and the presence of LeY antigen might be distinguishing markers for craniopharyngioma as well as Rathke cleft cyst versus epidermoid/dermoid.

    Histochemistry with Helix pomatia agglutinin in human germ cell tumors: detection of nongerminomatous components and correlation between HPA reactivity and radiosensitivity in germinomas (1993)

    Notes: Abstract Binding sites of Helix pomatia agglutinin (HPA) were examined in 32 patients with intracranial human germ cell tumors. HPA reactivity was found in vascular endothelial cells and erythrocytes of patients with blood type A or AB. HPA-positive neoplastic cells were seen in one yolk sac carcinoma in a patient with blood group. A, and in embryonal carcinomas and teratomas irrespective of blood group type. Although in 10 out of 18 germinomas neoplastic cells were totally negative for HPA, another 8 germinomas showed HPA-positive neoplastic cells which were distributed sporadically or in an area and independent of blood group types. HPA-negative germinoma patients showed a very good response to radiotherapy, whereas 4 out of 8 HPA-positive tumors showed poor radiosensitivity, with a residual lesion seen on computed tomography even after the total radiation dose of 40–50 Gy. These findings suggest that HPA-positive neoplastic cells in germinomas indicate components of differentiation of non-germinomatous germ cells. HPA-positive germinomas might be less radiosensitive than HPA-negative germinomas.

    Proliferative assessment of craniopharyngioma and epidermoid by nucleolar organizer region staining (1992)

    Notes: Abstract The histologic distinction between craniopharyngioma and epidermoid is equivocal. Eight craniopharyngiomas and ten epidermoids (including three dermoids) as well as nine rat (Wistar) abdominal skins that acted as control were investigated by a silver colloid method for nucleolar organizer regions (Ag-NORs). The mean number of Ag-NORs in at least 200 cells of both basal (columnar) epithelial cells and suprabasal (prickle) cells was evaluated. It was found that the mean number of Ag-NORs in basal cells of epidermoid and rat skin was significantly greater than that in suprabasal cells (P〈0.001 in nine of ten epidermoids and in all rat skins). On the other hand, of eight craniopharyngiomas, the mean Ag-NOR number in basal cells was not significantly different from that in suprabasal cells in five cases, and, further, the former was significantly smaller than the latter in the other three cases (P〈0.01 in two and P〈0.05 in one). These findings suggest that a stepwise maturation of the epithelial cells like that in mammalian skin epidermis exists in epidermoids but not in craniopharyngiomas. In craniopharyngiomas, the maturation of the epithelial cells seems to be considerably limited or lost from the aspect of proliferative potential as assessed by Ag-NOR score, which indicates neoplastic growth of craniopharyngiomas. Ag-NOR staining may thus be a useful method to distinguish craniopharyngioma from epidermoid.

    Notes: Abstract: We report herein the case of a 69-year-old man in whom rapid growth of a retroperitoneal rhabdomyosarcoma occurred following hemicolectomy for ascending colon cancer. On his first admission for surgery, a small lesion, 1.5 cm in diameter, was detected adjacent to the inner side of the left kidney by abdominal axial computed tomography (CT), which was initially suspected to be a benign lesion; however, a postoperative follow-up CT scan done 5 months later revealed that the lesion had enlarged remarkably to 8 cm in diameter. Thus, total resection was performed under the presumed diagnosis of a malignant retroperitoneal tumor. The tumor was found to be adjacent to the inner portion of the left kidney and covered by Gerota's fascia. As it involved the ileolumbar muscle and had a metastatic lymph node, complete resection was performed. The resected specimen was 8.5 × 6.5 × 5 cm in size and was histologically confirmed as a retroperitoneal rhabdomyosarcoma of embryonal type. Two courses of adjuvant chemotherapy with adriamycin, vincristine, and cyclophosphamide were given, and the patient has shown no signs of recurrence for 2 years since his second operation.

    Notes: Abstract We report herein the case of a 27-year-old woman found to have an abdominal desmoid tumor involving the xyphoid and costal chondrium associated with pregnancy. The patient was referred to our department on the third day after delivery for investigation of a fist-sized, firm tumor in the infrasternal angle, first noticed during the eighth month of gestation. Computed tomography and magnetic resonance imaging revealed a well-defined mass, 9×7.5 cm in size, invading the xyphoid. The tumor could be radically excised with the xyphoid, a lower part of sternum, and the chondrium of the bilateral sixth and seventh ribs, including 1.5 cm of free margin. The resected specimen measured 10×11.5×11.5 cm and weighed 395 g. Histological examination revealed the lesion to be a desmoid tumor consisting of spindle cells with small, elongated nuclei infiltrating dense collagenous fibers. The patient had an uneventful postoperative course and was discharged on the 11th postoperative day. There has been no evidence of recurrence in the 6 months since her operation. This case is of interest with regard to the possible contribution of sex hormones, especially estrogen, to desmoid tumor development.

    Notes: Abstract Specimens from 235 surgically treated cases of gastric cancer were examined for venous invasion in order to investigate its clinical significance. A total of 87 (37.0 per cent) cases showed histologic evidence of venous invasion, with the incidence being 48.3 per cent of 180 cases, after the exclusion of 55 cases where cancerous invasion was limited to the mucosa. The frequency of venous invasion varied with the gross type of tumor, the depth of penetration and the degree of differentiation, being highest in tumors of type 2 and moderately differentiated adenocarcinoma. It increased proportionately dependeing upon the depth of penetration and the incidence increased in cases where there was evident lymphatic invasion or lymph node metastasis. The long term survival rate significantly decreased in patients with venous invasion when compared to those without it. In this report, we also discuss the marked difference in the incidence of liver metastasis between gastric and colorectal carcinomas in relation to venous invasion of the primary tumor. Double staining with Victoria blue and hematoxylin-eosin for elastic fibers proved useful for detecting venous invasion in the carcinomatous tissue, though endothelial markers have great specificity for differentiating small veins from lymphatics.
