    Notes: Abstract The authors report the successful treatment of two cases of malignant germ-cell tumor. A 12-year-old patient with a pineal immature teratoma and increase of α-fetoprotein serum levels was treated with total excision and cisplatin, vinblastine, and bleomycin (PVB) in combination given twice. One year later, he had a recurrence of tumor in the right occipital lobe, which was totally removed, and yolk sac tumor was verified. As subsequent adjuvant chemotherapy, PVB was given in four courses over 1.5 years, together with one course of cisplatinetoposide (PE) therapy. The patient is well 5 years and 9 months after the first operation. In the second case, a 19-year-old patient with a pineal mixed germ-cell tumor, composed of germinoma, yolk sac tumor, and embryonal carcinoma, was treated with total excision, followed by four courses of PVB therapy and one of PE. She has done well in the 4.5 years since the initial treatment. Thus, aggressive extirpation of the lesion and subsequent combination chemotherapy using cisplatin and other multiple drugs, given in at least four courses over 1.5 years, even if tumor markers return to within normal limits, might provide successful treatment for malignant germ-cell tumors.

    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.

    Germinoma in cerebral hemisphere associated with Down syndrome (1997)
    Springer

    Notes: Abstract A Down syndrome patient with germinoma developing in the cerebral hemisphere is reported. A review of the literature yielded only 14 cases of Down syndrome with brain tumors, including our case. This finding of brain tumors in patients with Down syndrome may reflect chance occurrence. However, it is of interest in this regard that in 6 of the 14 (43%) reported cases the lesions were intracranial germ cell tumors.

    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.
