    Notes: Abstract Long-term manometry of the tubular esophagus was performed in 20 consecutive patients (18 females, 2 males; median age 56.5 years) with progressive systemic sclerosis (PSS) and a control group of 20 healthy subjects (18 females, 2 males; median age 56.5 years). The measurements were performed via a data logger of 1 MByte memory capacity with the help of two pressure sensors placed 8 and 18 cm above the lower esophageal sphincter. Esophageal contractions were analyzed with respect to pressure amplitudes in the esophagus distal and proximal, quotient of pressure amplitudes distal/proximal, number of contraction waves in a 24-h period, and kind of spreading (propulsive, simultaneous). In the PSS group there was a significant decrease in pressure amplitudes in the distal sensor (median 31.5 versus 39.5 mbar in controls, P 〈 0.02), in the quotient of pressure amplitudes distal/proximal (median 0.885 versus 1.25 in controls, P 〈 0.001), in the number of waves in 24 h (median 939.5 versus 1656 in controls, P 〈 0.01), and in the occurrence of propulsive waves (median 34% versus 57% in controls, P 〈 0.01). Fifteen patients (75%) had hypomotility disorders as compared to the control group, in which the lower limit of normal values was defined by the 5th percentile of descriptive analysis. These first data of long-term manometry in patients with PSS indicate that long-term manometry may be an effective method for identifying esophageal involvement in PSS.

    Description / Table of Contents: Zusammenfassung Die Epitheliotropie cutaner Lymphome ist ein letztlich ungeklärtes Phänomen, das Epidermis wie epidermale Adnexe gleichermaßen betrifft. Dieses Phänomen wird in besonderer Weise bei Tumoren beobachtet, deren T-Zell-Genese wahrscheinlich ist. Allerdings ist es auch bei B-Zellymphomen (Immunocytomen) nachweisbar und insofern kein strenges Kriterium für die biologische Herkunft eines Lymphoms. Bei Keimzentrumstumoren fehlt in unserem Material die Epidermotropie. Jedoch muß eine aktive Einwanderung von Lymphomzellen in das Epithel von passiven, durch die Ausdehnung des Tumors bedingten druckverursachten Phänomenen unterschieden werden. Morphologisch können sich beide Reaktionen vollständig gleichen. Es wird eingehend dargelegt, daß Pautrier Mikroabscesse lediglich als Momentaufnahme des Epidermotropismus anzusehen sind und daß ihnen damit keine besondere Spezifität zukommt.
    Notes: Summary Epitheliotropia of malignant skin lymphomas is an unexplained phenomenon which equally affects epidermis and ectodermal appendages. This phenomenon is found especially in tumors of probable T-cell origin. However it can also be observed in B-cell lymphomas (immunocytomas) and is therefore not an exact criterium for the biological origin of a lymphoma. In the case of germinal center tumors we could not find evidence of epitheliotropia. An active invasion of neoplastic cellular infiltrate into the epithelium must be differentiated from the phenomenons caused by passive pressure, resulting from the expansion of the tumor. However, one has to remember that epitheliotropic malignant lymphomas invade the epidermis in all stages of development. It is shown, that Pautrier microabscesses are only a special non specific aspect of epidermotropia.
