Abstract

BACKGROUND

This report describes a case of solitary tracheal lymphoma in a 14-year-old alpaca mare.

CASE PRESENTATION

The alpaca was referred for dyspnea and inspiratory noise. The clinical examination included complete blood cell count, blood chemistry, endoscopy, ultrasound, radiographs, and computed tomography (CT). A solitary tracheal intraluminal and juxtatracheal lymphoma was diagnosed by fine needle aspiration (FNA). The owner requested euthanasia due to the uncertain prognosis. At postmortem examination, the presence of solitary lymphoma without involvement of other organs was confirmed. Immunohistochemical analysis confirmed a B-cell origin.

CONCLUSIONS

Although multicentric lymphoma is the most commonly described neoplasia affecting South American camelids (SAC), solitary forms of the disease may occur.

摘要

背景

本报告描述了一例 14 岁羊驼母马的孤立性气管淋巴瘤。

病例介绍

这头羊驼因呼吸困难和吸气性杂音被转诊。临床检查包括全血细胞计数、血液化学、内窥镜检查、超声、射线照相和计算机断层扫描（CT）。通过细针抽吸（FNA）诊断为孤立性气管腔内和气管旁淋巴瘤。由于预后不确定，主人要求安乐死。在尸检时，确认存在孤立性淋巴瘤而无其他器官受累。免疫组织化学分析证实为 B 细胞起源。
