    Notes: Abstract Urine of the black-tailed deer is the source of the “deer lactone,” which is deposited on the tarsal gland tufts by “rub-urination.” The enantiomer composition of the lactone from the urine of the female is 89(R)-(−)/11(S)-(+). Responses by deer were strongest toward the synthetic racemic lactone in the social test and toward the natural lactone in the choice test. In both tests, the (−)- lactone released slightly stronger responses than its enantiomer.

    Notes: Abstract Black-tailed deer (Odocoileus hemionus columbianus) discriminate between the geometric isomers of a lactone used as a pheromone by the species. They react strongly to (Z)-4-hydroxy-6-dodeceonic acid lactone, which occurs in their tarsal scent, but the response to theE isomer did not differ from the response to the solvent. The isomers were applied to one member of a group of freely interacting deer, and the sniffing, licking, and following responses were recorded. The synthesis of the geometric isomers of the lactone is described.

    Notes: Abstract Two subspecies of deer, black-tailed deer (Odocoileus hemionus columbianus) and Rocky Mountain mule deer (O. h. hemionus) were exposed to the tarsal scents of both subspecies in a social setting. The scent was sprayed on one individual in a group. The responses, consisting of sniffing, licking, and following, were stronger to each subspecies' own tarsal scent. This discrimination may be important for sexual isolation in areas where the ranges of the two species overlap.

    Notes: Abstract This is apparently the first report on connatal hemihypertrophy with malignant pheochromocytoma. The coincidence of hemihypertrophy with other diseases, particularly neuroectodermal dysplasias on the one hand and the frequent association of neuroectodermal dysplasias with pheochromocytoma on the other, are emphasized. Furthermore, basically known particularities of this case as malignancy of the tumor, the unusual size of the tumor in children, and the normal catecholamine levels in serum as well as the normal excretion of vanillylmandelic acid are discussed.

    Notes: Summary The kidneys of 18 autopsy cases of myelomonocytic leukemia (MML) were examined for MML-specific features. Nine cases of chronic lymphocytic leukemia (CLL) served as controls. The kidneys of the cases of MML showed macroscopically detectable sings of hemorrhagic diathesis and secondary uric acid diathesis more often than those of CLL. In the MML group most of the kidneys weighed more than the normal average for the corresponding age group, but the average renal weights for the 2 groups were about the same. Renal weight and grade of leukemic infiltration, particularly in MML, revealed no significant positive correlation. In most of the cases of MML there were unevenly distributed poorly defined leukemic, infiltrates in the renal cortex and medulla. The histology resembled that of pyelonephritis. In CLL, on the other hand, the leukemic infiltrates were usually sharply defined and localized in foci in the outer cortex and the corticomedullary border region. Renal dysfunction in cases of MML has been attributed by others to hyperlysozymemia. It was found occasionally but there was no MML-typical morphological substrate in our material. Hyaline droplet change of the tubular epithelium was more frequent and more pronounced in MML than in CLL. However, we also determined that it was nonspecific and that it was not a parameter of cell damage. Tubular hyaline droplet change and the morphological criteria of acute renal failure were not positively correlated with the degree of leukemic infiltration of the kidneys or with the leukemic proliferation as a whole. Instead, they were considered to be signs and symptoms of accompanying or secondary diseases which complicated the leukemia.

    Notes: Summary A 76 year old man with mycosis fungoides developed an immunoblastic sarcoma and a leukemic blood picture in the final tumor stage after 6 years, in which the disease had clinically progressed in a typical manner. The results of histological and cytochemical studies of autopsy material are presented. Based on these findings and evidence of the T cell nature of mycosis fungoides, the immunoblastic sarcoma observed in the terminal stage of this case of mycosis fungoides might be of the rare T cell type.

    Description / Table of Contents: Zusammenfassung Mit der vorliegenden Mitteilung wird u.W. erstmals eine isolierte kongenitale Mitralstenose bei einem Zwillingspaar — 7 Monate alt gewordener weiblicher Säugling (Zustand nach frischer, notfallmäßig ausgeführter Mitralvalvotomie), 2 9/12 Jahre alt gewordenes weibliches Kleinkind (Zustand nach prothetischem Mitralklappenersatz 6 Monate vor dem Tode) — beschrieben. Die pathologisch-anatomischen Befunde werden dokumentiert1 und diskutiert. Als Todesursache war bei dem einen Kinde ein Herzversagen nach operativ gesetzter Mitralklappeninsuffizienz anzunehmen, bei dem anderen Kinde ein Herzversagen infolge Ventildysfunktion. Das freie Klappenspiel des Björk-Shiley-Ventils, eines scharnierlosen Deckelventils, wurde mehr und mehr behindert durch einen zirkulär den Prothesenrand überwuchernden fibrösen Endokardwulst. Es resultierte eine Ventildysfunktion im Sinne eines kombinierten Mitralklappenfehlers. Schrittmacher der überschießenden Bindegewebs- und Endokardbildung dürfte eine lokale Gerinnselbildung im Prothesenlager und am Prothesen-ring gewesen sein, nachdem eine ausreichende Antikoagulantien-Applikation wegen post-operativer Serumhepatitis bei diesem Kinde nicht hatte betrieben werden können.
    Notes: Summary The pathoanatomical features of isolated congenital mitral stenosis in female twins are presented. At the age of 7 months one of the infants underwent an emergency mitral valvotomy and died the next day due to mitral insufficiency. A total mitral valvectomy and an implantation of a Björk-Shiley prosthesis were performed on the second child at the age of 27 months. Death occurred 6 months later due to malfunction of the prosthesis caused by a circular fibrous endocardial bulge on both the atrial and ventricular side of the prosthesis. The bulging endocardial fibrosis may have been favored by a local thrombosis, which was found circularly around the bed of the prosthesis after it was removed. Since the child suffered from postoperative serum hepatitis, anticoagulants could not be applied on a regular basis in sufficient doses. The relation of the endocardial fibroelastosis to the congenital valve disease and the implantation of a prosthesis is discussed. The site of the postoperative valve in the first child and the state of the second child after implantation of the mitral valve prosthesis are discussed in detail.

    Description / Table of Contents: Zusammenfassung In der vorliegenden Studie wurden 23 Lymphome der Augen-, Lid- und Orbitalregion ausgewertet. Sie stammten aus einem nicht ausgewählten bioptischen Untersuchungsgut des Pathologischen Instituts der Universität Kiel und des Lymphknotenregisters bei der Deutschen Gesellschaft für Pathologie. Es handelte sich dabei um 12 maligne und 11 benigne Lymphome. Die malignen Lymphome stellten jeweils Non-Hodgkin-Lymphome dar. Unter den letzteren fanden wir elfmal ein Immunocytom, ein malignes Lymphom mit niedrigem Malignitätsgrad — dagegen nur einen Fall eines malignen Lymphoms mit hohem Malignitätsgrad, ein centroblastisches Lymphom. Die Diagnose eines benignen Lymphoms wurde jeweils durch die von uns erhobenen katamnestischen Angaben bestätigt. Während sich das benigne Lymphom in 7 von 11 Fällen in der Conjunctiva entwickelt hatte, war dies bei nur 2 von 11 Fällen mit Immunocytom zu beobachten. Das Immunocytom stellt einen Tumor dar, der aus Lymphocyten und Plasmazellen oder plasmocytoiden Zellen besteht und meist PAS-positive globuläre Einschlüsse in Kern und/oder Cytoplasma der Plasma- oder plasmocytoiden Zellen aufweist.
    Notes: Summary Twenty-three lymphomas of the eye, eyelid, and orbit were chosen for study from biopsy material of the Department of Pathology, University of Kiel, and the Lymph Node Registry in Kiel. There were 12 malignant non-Hodgkin's lymphomas and 11 benign lymphomas. Catamnestic examination confirmed the histologic diagnosis in all 11 cases of benign lymphoma. Eleven of the malignant lymphomas represented immunocytomas and were therefore of low-grade malignancy. In contrast, there was only one case of malignant lymphoma of high-grade malignancy, which was diagnosed as centroblastic lymphoma. The immunocytoma was retrobulbar in one third of our cases and conjunctival in only 2 cases, whereas benign lymphoma had developed in the conjunctiva in 7 of 11 cases. Immunocytoma represents a tumor composed of lymphocytes and plasma cells or plasmacytoid cells. PAS-positive globular inclusions are usually found in the nucleus and/or cytoplasm of the plasma cells or plasmacytoid cells.

    Description / Table of Contents: Zusammenfassung An folgenden Beispielen aus dem eigenen Operations- und autoptischen Untersuchungsgut der letzten 5 Jahre wird die spezielle Pathologie rekonstruierbarer oder prothetisch korrigierbarer kongenitaler Herzfehler der Mitralregion dargestellt: 1. Kongenitale isolierte Mitralstenose bei einem weiblichen Zwillingspaar (7 Monate alt gewordener Säugling bzw. 2 9/12 Jahre alt gewordenes Kleinkind) 2. kongenitale isolierte Mitralinsuffizienz bei einem 7 1/2jährigen Jungen 3. kombiniertes, unreines Mitralvitium bei parachute-valveähnlicher Mitralklappen-anomalie, kombiniert mit einer Hypoplasie der Aorta ascendens et descendens, bei einem 6 1/2jährigen Mädchen 4. kongenitale Mitralinsuffizienz bei parachute mitral valve, kombiniert mit supravalvulärer Aortenstenose und multiplen peripheren Pulmonalarterienstenosen, bei einem 13 1/4 Jahre alten Jungen 5. Insuffizienz der in Mitralposition invertierten Tricuspidalklappe bei sog. korrigierter Transposition der großen Gefäße bei einem 6 Jahre alt gewordenen Jungen und mit Ebsteinscher Anomalie bei einem 2 1/2jährigen Jungen 6. zweites Mitralostium im aortalen Mitralsegel bei partiellem AV-Kanal bei einem 6 3/4 Jahre alt gewordenen Mädchen mit Ellis-van Creveld-Syndrom 7. Bland-White-Garland-Syndrom mit relativer Mitralklappeninsuffizienz bei einem 5 Monate und bei einem 4 Monate alten männlichen Säugling. Trotz der Wiederkehr ähnlicher oder vergleichbarer Befunde ist jedes der von uns beobachteten kongenitalen oder frühkindlich erworbenen, nicht entzündlichen Mitralvitien für sich gestaltlich verschieden. Die operative Korrektur erforderte daher in jedem Falle ein individuelles Vorgehen. Einerseits ist nur unter Verwendung der klinischen Untersuchungsbefunde aus der speziellen Pathologie verläßlich auf den Grad der Fehlfunktion der AV-Klappe in Mitralposition rückzuschließen. Andererseits läßt sich der detaillierte pathologisch-anatomische Befund bei kongenitalen Mitralvitien trotz der heute verfügbaren kardiodiagnostischen Methoden erst bei der direkten Inspektion — sei es unter der Sicht des Operateurs, sei es autoptisch — erheben. Neben dem jeweiligen Klappenbefund werden die für Mitralvitien typischen Sekundärveränderungen besprochen — so die links atrial betonte Endocard-fibroelastose und die Herzkonfiguration. Auf die anatomischen Voraussetzungen für ein chirurgisch rekonstruktives Vorgehen oder einen prothetischen Herzklappenersatz wird hingewiesen.
    Notes: Summary The special pathology of reconstructable or only prosthetically correctable congenital malformations of the mitral valve is described on the basis of the following examples taken from our own operative and autopsy material of the last 5 years: 1. Congenital isolated mitral stenosis in female twins (7 month old infant and 33 month old child). 2. Congenital isolated mitral insufficiency in a 7 1/2 year old boy. 3. Combined mixed mitral valve malformations with a parachute valve-like mitral valve anomaly, combined with hypoplasia of the ascending and descending aortas, in a 6 1/2 year old girl. 4. Congenital mitral insufficiency with a parachute mitral value, combined with supravalvular aortic stenosis and multiple peripheral stenoses of the pulmonary arteries in a 13 1/4 year old boy. 5. Insufficiency of the mitrally inverted tricuspid value with so-called corrected transposition of the great vessels in a 6 year old boy and with Ebstein's anomaly in a 2 1/2 year old boy. 6. A second mitral ostium in the aortic mitral leaflet with a partial atrioventricular canal in a 6 3/4 year old girl with Ellis-van Creveld syndrome. 7. Bland-White-Garland syndrome with relative mitral insufficiency in a 5 month old and a 4 month old boy. Despite the recurrence of similar and comparable findings, each of our cases of congenital or early acquired noninfectious mitral valve malformation was formally different. This was also true for the cases of congenital isolated mitral stenosis in twins. Therefore, surgical correction requires a unique procedure for each case. It is possible to reliably infer the degree of malfunction of the atrioventricular valve in a mitral position from the special pathology only by considering the clinical data. On the other hand, a detailed evaluation of congenital mitral valve malformations is possible only through direct inspection—either by the surgeon or through an autopsy—despite modern cardiodiagnostic methods. Typical secondary findings are also discussed—for instance, endocardial fibrosis of the left atrium and the configuration of the heart. The anatomical prerequisites for surgical reconstruction or replacement of the valve with a prosthesis are mentioned.
