    Notes: Ectopic mammary tissue in the inguinal region giving rise to a hamartoma is reported. This localization of ectopic breast is infrequent and hamartomas of the breast at this site have not been described previously. The unusual size of the lesion caused pre-operative diagnostic difficulties.

    Notes: Abstract PURPOSE: Adenomatous polyposis coli protein, glycogen synthetase kinase-3-beta, T cell transcription factor/lymphoid enhancer-binding factor, and beta-catenin modulate cell differentiation and proliferation via the expression of effector genes. It has recently been postulated that betacatenin is a potent oncogene of sporadic colorectal carcinogenesis and a prognostic tumor marker. Our aim was to investigate whether the nuclear overexpression of betacatenin, possibly caused by mutations in exon 3 of betacatenin (CTNNB1), is correlated with distant metastatic spread or disease-free survival in rectal carcinoma. METHODS: Immunohistochemical analysis was performed with an anti-beta-catenin-monoclonal antibody on paraffin sections of two groups of patients (n=2 × 77) with rectal carcinoma curatively treated by surgery alone. The patients selected were all free of local disease, to exclude surgical influence. Patient groups were matched for age, gender, International Union Against Cancer stage, and year of operation (1982 to 1991) and differed only in subsequent metachronous distant metastatic spread. Follow-up was prospective (median, 9.6 years). Three staining patterns were defined: membranous (normal), diffuse cytoplasmic (pathologic), and intense nuclear staining (pathologic). When intense nuclear staining was defined, the specimen was microdissected. Then, DNA was isolated, polymerase chain reaction-amplified, and sequenced to detect mutations in exon 3. RESULTS: Nuclear overexpression of beta-catenin correlated neither with distant metastatic spread (chisquared, 0.37;P=0.79) nor with disease-free survival (log-rank with trend,P=0.62). No mutations were found in the area of the serine/threonine-kinase glycogen synthetase kinase-3-beta-phosphorylation site in exon 3 (CTNNB1) of beta-catenin. CONCLUSION: Although beta-catenin seems to play an important role in early colorectal carcinogenesis, its value as a prognostic marker is questionable. It must be assumed that metastatic ability is determined by other factors than the disturbance of the beta-catenin T cell transcription factor/lymphoid enhancer-binding factor cascade and that other mechanisms might cause the observed nuclear translocation of beta-catenin.

    Notes: Summary A rare case of a 43-year-old man with polyneuropathy, monoclonal gammopathy, myeloma and Castleman's disease of plasma cell type was diagnosed. Immunohistological examination of the lymph node with Castleman's disease showed polyclonal binding while the myeloma was monoclonal containing IgA with λ-light chains. At the immunoelectrophoresis IgA/IgA paraprotein was demonstrated. The possible pathogenetical relationship between polyneuropathy and plasmacytoma as well as Castleman's disease will be discussed.

    Description / Table of Contents: Résumé. Le traitement standard d'un cancer du rectum est chirurgical, toutefois la radiochimiothérapie pré-opératoire est appelée à jouer un rôle croissant, en particulier dans les formes localement avancées de la maladie. Afin d'estimer le pronostic et l'effet de la radiochimiothérapie, il est important d'évaluer les constatations pathologiques secondaires à la radio-chimiothérapie. Nous avons analysé les prélèvements opératoires de dix-sept patients après radio-chimiothérapie pré-opératoire dans le but d'estimer et de graduer les réactions histologiques. Nous décrivons également une proposition d'un système de graduation de la régression tumorale, ce qui n'existe pas encore dans la littérature. A l'exception d'un cancer, toutes les tumeurs présentaient des degrés divers de régression. Une régression totale n'a pas été observée après une technique standard d'analyses pathologiques. Dans un seul de nos cas, une résection curative locale n'a pas été possible. Nous pensons que la radio-chimiothérapie pré-opératoire est capable de réduire le volume tumoral à un point tel qu'il est possible d'opérer des cas qui, initialement, n'auraient pas pu être traités de manière curative. Nous conseillous une technique standard d'analyses pathologiques et de graduation de la régression tumorale qui devrait être utile à l'étude comparative des résultats chirurgicaux et de la radio-chimiothérapie du cancer du rectum.
    Notes: Abstract. The standard therapy for rectal carcinoma is surgical, however, preoperative radiochemotherapy will play an increasing role especially in locally advanced disease. To estimate the prognosis and the effect of radiochemotherapy the postradiochemotherapeutical pathological features are important to assess. We examined the surgical specimens of 17 patients after preoperative radiochemotherapy to estimate and grade the histological reactions. A proposal for a grading system for tumor regression (not yet available in the literature) has also been described. All but one of the carcinomas showed different degrees of tumor regression. A total regression was not observed after standardised pathological work up. In only one case a locally curative resection was not possible. We think that preoperative radiochemotherapy is able to reduce tumor mass thus achieving operability in non-curatively operable cases. We recommend standards of pathological work up and regression grading for further studies comparing surgery and radiochemotherapy of rectal carcinoma.

    Description / Table of Contents: Summary We report the case of a seven months old girl, presenting with diarrhea refractory to therapy and stagnation of growth. The dehydrated infant developed edemas. It showed considerable diminution of humoral and cellular immunoresponse. Inspite of several vaccinations there was no response to a multiple-puncture skin test. Thus we suspected a combined immunodeficiency with protein-losing enteropathy, as massive substitution of protein was necessary. An enteral scintigraphy showed an enhancement in the right upper abdomen. During the following laparotomy a 15-cm-segment of the small bowel was resected, as it appeared to be transformed into a cystic lymphoma. Consequently all pathologic findings disappeared. Discussion: This case is of interest because an intestinal lymphangioma was mimicking a combined immunodeficiency, the indication for intervention was given by scintigraphy, and because excision of a short bowel segment restored normality.
    Notes: Zusammenfassung Wir berichten über ein 7 Monate altes Mädchen, das mit therapieresistenten Durchfällen und Wachstumsstillstand vorgestellt wurde. Das dehydrierte Kind entwickelte Ödeme und wies eine erhebliche Verminderung humoraler und zellulärer Abwehrfunktionen auf. Somit äußerten wir den Verdacht auf einen kombinierten Immundefekt mit enteralem Eiweißverlust, da das Kind massive Proteinsubstitutionen benötigte. Wir führten eine enterale Szintigraphie durch, die eine deutliche Mehranreicherung im rechten Oberbauch zeigte. Bei der anschließenden Laparotomie wurde ein 15 cm langer, durch ein Lymphangiom zystisch veränderter Dünndarmabschnitt entfernt. Danach normalisierten sich alle Befunde. Diskussion: Die Besonderheit dieses Falls liegt in der Simulation eines kombinierten Immundefekts durch ein intestinales Lymphangiom, das Stellen der Operationsindikation per Szintigraphie und die Heilung durch kurzstreckige Exzision.

    Description / Table of Contents: Abstract Intraoperative autotransfusion (MAT), preoperative autologous blood donation, and preoperative normovolaemic haemodilution are three different methods to avoid homologous blood transfusion during surgical procedures. The controversial use of MAT via cell saver in tumour surgery as well as contamination of the operative field with urine illustrate the particular difficulties of autologous blood transfusion in connection with radical prostatectomy. We investigated changes in the osmotic resistance of the retransfused red blood cells (RBC), bacterial contamination, changes in coagulation parameters, and the presence of tumour cells. Patients and methods: After written informed consent, 24 patients who presented for radical prostatectomy were randomly allocated to either a group that used MAT or a group that used homologous transfusion. The patients received „balanced anaesthesia” with midazolam, fentanyl, atracurium, and nitrous oxide/oxygen. The analysed parameters from the preoperative period to the 3rd postoperative day are shown in Table 1. The Haemonetics 3 Plus Cell Saver was used for autotransfusion. Results: Our results showed that the haematologic parameters, coagulation factors, and serum chemistry did not differ between the two groups (Tables 2–4). However, there were significant differences during the investigated period. The osmotic resistance of the salvaged RBCs was higher than that preoperatively. Furthermore, there were no tumour cells in the autologous salvaged RBCs. Conclusion: Our results showed no decrease in the quality of the autotransfused RBCs, urine was not retransfused; and there were no significant differences between the groups postoperatively. Although there were no tumour cells in the salvaged blood, the possibility of blood irradiation is discussed. We concluded that because of the risk of infection of homologous blood products, MAT is a safe possibility to reduce the amount of homologous blood transfusion required in connection with radical prostatectomy.
    Notes: Zusammenfassung Mit der intraoperativen maschinellen Autotransfusion (MAT) steht heute, neben anderen Möglichkeiten wie der präoperativen Eigenblutspende und der präoperativen normovolämischen Hämodilution, ein Verfahren zur Vermeidung von Fremdbluttransfusion zur Verfügung. Der Einsatz der MAT in der Tumorchirurgie sowie die Urinkontamination des OP-Situs zeigen die besonder Problematik der Qualitätssicherung des autologen Blutersatzes bei radikalen Prostatektomien. Neben möglichen Qualitätsveränderungen der retransfundierten Erythrozyten galt es, die Infektionsgefährdung, Gerinnungsveränderungen und eine mögliche Retransfusion von Tumorzellen zu untersuchen. Die Untersuchung wurde an insgesamt 24 Patienten der Urologischen Universitätsklinik Erlangen im Rahmen einer prospektiv randomisierten Studie durchgeführt. Anhand der Ergebnisse fand sich keine Qualitätsminderung der autotransfundierten Erythrozyten, Urin wurde nicht retransfundiert, und im postoperativen Verlauf konnten keine signifikanten Unterschiede zwischen den Vergleichsgruppen nachgewiesen werden. Tumorzellen im Cell-Saver-Erythrozytenkonzentrat (CS-EK) fanden sich nicht, eine Bestrahlung der CS-EK wird diskutiert. Gerade vor dem Hintergrund des bestehenden Infektionsrisikos homologer Blutprodukte sollte die MAT bei radikalen Prostatektomien als Möglichkeit zur Reduktion des Fremdblutbedarfs genutzt werden.

    Notes: Summary The effect of combined surgical and chemotherapeutic treatment on Lewis lung carcinoma was studied. The i.m. implanted primary tumor was removed on the 10th day after transplantation, and the survival of mice was registered. Cyclophosphamide proved to be the most effective among the drugs studied (Cyclophosphamide, 5-FU, DBD, CCNU, Adriamycin, Vincristin, Hexyldeoxyuridine). Using different schedules (pre- and/or post-operative treatment) the pre- and post-operative drug administration was the most advantageous. Combined therapy showed always better effect than monotherapy.
