Neoplasm in South American camelids (SAC) are commonly described. The most frequently reported type of neoplasm are lymphomas and difference in the age suffering from lymphomas of and llamas is seen. This report describes a case of a solitary lymphoma in a 5 years and 9 month old llama mare displaying the approach of diagnostic imaging and successful surgical treatment.
The llama was referred to the clinic for dyspnoea and inspiratory abnormal respiratory sounds. The clinical examination comprised blood cell count, ultrasonographic and radiographic examinations, endoscopy and fine needle aspiration cytology of a mass detected in the mid cervical region. The mass was surgically removed. Histopathological examination of the surgically removed mass diagnosed a malignant T-cell- lymphoma. According to the results of the clinical, ultrasonographic and radiographic examinations no tumor invasion was apparent in distant organs and the llama was discharged from the clinic seven days after surgery.
Lymphoma has been reported to be the most common neoplasia in camelids and are more often described in young alpacas and in adult llamas. To the author´s knowledge the case presented here is the first that described a broad panel of diagnostic tools including ultrasound, radiographs, endoscopy, fine needle aspiration cytology and histopathoogical examination as well as a successful surgical treatment of a solitary lymphoma in camelids.
南美的驼羊（SAC）中常描述肿瘤。最常报告的肿瘤类型是淋巴瘤，并且在患有淋巴瘤的年龄上存在差异。本报告描述了一例 5 岁 9 个月大的母驼羊的孤立性淋巴瘤病例，介绍了诊断影像学和成功手术治疗的方法。
这只驼羊因呼吸困难和吸气异常呼吸音而被转诊到诊所。临床检查包括血常规、超声和放射学检查、内窥镜检查和在中颈区发现的肿块的细针抽吸细胞学检查。肿块被手术切除。手术切除肿块的组织病理学检查诊断为恶性 T 细胞淋巴瘤。根据临床、超声和放射学检查的结果，没有发现远处器官的肿瘤侵犯，驼羊在手术后 7 天出院。
淋巴瘤已被报道为驼羊中最常见的肿瘤，并且在年轻的羊驼和成年的骆马中更为常见。据作者所知，本报告中描述的病例是首例使用广泛的诊断工具，包括超声、放射学、内窥镜检查、细针抽吸细胞学和组织病理学检查，以及成功治疗驼羊的孤立性淋巴瘤的病例。
