Retropharyngeale Manifestation eines T-Zell-reichen B-Zell-Lymphoms bei einem 7-jährigen Isländerwallach

Zusammenfassung

Ein 7-jähriger Isländerwallach wurde mit akuter hochgradiger Dyspnoe sowie seit 6 Wochen bestehendem eitrigem Nasenausfluss vorgestellt. Klinisch standen bei der Erstuntersuchung eine hochgradige Schwellung der Mandibular- und Retropharyngeallymphknoten sowie eine gemischte Dyspnoe im Vordergrund.

Mittels Labordiagnostik, Endoskopie und zytologischer Untersuchung eines Feinnadelaspirates aus einem Mandibularlymphknoten konnte die Diagnose eines malignen Lymphoms gestellt werden. Der Wallach wurde auf Grund der infausten Prognose bei deutlich gestörtem Allgemeinbefinden euthanasiert. Die pathohistologische Untersuchung ergab ein multizentrisches T-Zell-reiches B-Zell-Lymphom.

Abstract

A 7-year-old Icelandic gelding was presented with acute severe dyspnea of one day duration and purulent nasal discharge that had been present for 6 weeks. Clinically, the initial examination focused on severe enlargement of the mandibular and retropharyngeal lymph nodes as well as a mixed dyspnea.

The diagnosis of a malignant lymphoma was evident following laboratory diagnostics, endoscopy, and cytological examination of a fine needle aspiration of a mandibular lymph node. The gelding was euthanized due to the poor prognosis and a significantly disturbed general condition. Pathohistological examination revealed a multicentric T-cell-rich B-cell lymphoma.
