Infiltrative laryngeal lipoma in a Yorkshire Terrier as cause of severe dyspnoea

Summary

A 10-year-old Yorkshire Terrier with suspected laryngeal paralysis was referred for further examination and surgical treatment. The dog displayed severe dyspnoea and dysphonia. Ventrolateral to the larynx a soft-elastic mass of 2 cm diameter was palpated and confirmed by radiography. Histopathological examination of the resected mass revealed an infiltrative lipoma/lipoma. Although the dog totally recovered after surgery, the prognosis remains guarded due to the high risk of a recurrence. Tumours of the larynx in general and an infiltrative lipoma specifically should be added to the list of differential diagnosis in dogs presented with clinical signs that could be misinterpreted as laryngeal paralysis.

Zusammenfassung

Ein 10 Jahre alter Yorkshire Terrier mit Verdacht auf eine Larynxparalyse wurde zur diagnostischen Abklärung und chirurgischen Therapie überwiesen. Der Hund zeigte eine schwere Dyspnoe sowie Stimmverlust. Ventrolateral des Larynx ließ sich eine elastische Umfangsvermehrung von 2 cm Durchmesser palpieren. Die histopathologische Untersuchung der resezierten Umfangsvermehrung wies ein infiltratives Lipom/Lipom nach. Aufgrund des infiltrativen Charakters der Neoplasie besteht trotz vollständiger klinischer Wiederherstellung des Tieres aufgrund des hohen Risikos eines Rezidivs eine vorsichtige Prognose. Tumore im Bereich des Larynx im Allgemeinen und speziell infiltrative Lipome sollten bei Hunden mit klinischen Anzeichen einer Larynxparalyse differenzialdiagnostisch in Betracht gezogen werden.
