Abstract

This retrospective study of neoplasia in prosimians in human care reports histologically diagnosed cases from the archives of a nondomestic species pathology service between 1995 and 2022, primarily submitted from zoological institutions. To date, the only prior retrospective study of neoplasia in prosimians, published in 2009, was conducted with cases from a single institution specializing in prosimian noninvasive research and care. In the present study, a total of 153 neoplasms from 109 individuals were identified in the pathology service archives. The most commonly affected species belonged to the Lemuridae (92/109, 84.4%), particularly ring-tailed lemurs (Lemur catta; 55/109, 50.5%), black-and-white ruffed lemurs (Varecia variegata; 19/109, 17.4%), and red ruffed lemurs (Varecia rubra; 14/109, 12.8%). The digestive (49/153, 32.0%), reproductive (35/153, 22.9%), and integumentary (30/153, 19.6%) systems were most commonly affected. Hepatocellular neoplasia was the most common neoplasm overall (35/153, 22.9%), with a large proportion of hepatocellular carcinoma (23/35, 65.7%), suggesting a possible predisposition to this tumor in prosimians. The findings support aggressive behavior of these tumors in prosimians, and a majority (13/23, 56.5%) of cases had evidence of metastasis at the time of submission. Mammary neoplasia was also common (25/153, 16.3%) and predominantly malignant (18/25, 72.0%), in contrast with previous literature, although metastasis was uncommonly reported. The most common integumentary neoplasms were papillomas (12/30, 40.0%), and one report identified squamous cell carcinoma arising directly from a squamous papilloma. Several tumor types are reported herein for the first time in prosimian species, to the authors' knowledge. A literature review identifying additional cases reported since 2009 is also reported. This study contributes a large number of prosimian neoplasia cases to the existing literature to help determine trends in zoological collections and to inform captive prosimian health management.

回顾 1995 年至 2022 年人类饲养的濒危动物瘤变情况。
这项关于濒危动物瘤变的回顾性研究报告了 1995 年至 2022 年间非家养物种病理服务档案中的组织学诊断病例,这些病例主要来自动物学机构。迄今为止,唯一一项关于濒危动物肿瘤的回顾性研究发表于 2009 年,研究对象是一家专门从事濒危动物无创研究和护理的机构。在本研究中,病理服务档案共发现了来自 109 个个体的 153 例肿瘤。最常见的肿瘤属于狐猴科(92/109,84.4%),尤其是环尾狐猴(Lemur catta;55/109,50.5%)、黑白脊狐猴(Varecia variegata;19/109,17.4%)和红脊狐猴(Varecia rubra;14/109,12.8%)。最常受影响的是消化系统(49/153,32.0%)、生殖系统(35/153,22.9%)和皮肤系统(30/153,19.6%)。肝细胞瘤是最常见的肿瘤(35/153,22.9%),其中肝细胞癌占很大比例(23/35,65.7%),这表明长尾猴可能有患这种肿瘤的倾向。研究结果表明,这些肿瘤在濒危动物中具有侵袭性,大多数病例(13/23,56.5%)在提交病例时已有转移迹象。乳腺肿瘤也很常见(25/153,16.3%),而且主要是恶性的(18/25,72.0%),这与以前的文献不同,尽管转移的报道并不多见。最常见的皮肤肿瘤是乳头状瘤(12/30,40.0%),其中一份报告发现鳞状细胞癌直接来源于鳞状乳头状瘤。据作者所知,有几种肿瘤类型在本报告中首次出现在颊兽类中。此外,作者还对 2009 年以来报告的其他病例进行了文献综述。这项研究为现有文献提供了大量的濒危动物肿瘤病例,有助于确定动物保藏的趋势,并为圈养濒危动物的健康管理提供信息。

期刊介绍: The Journal of Zoo and Wildlife Medicine (JZWM) is considered one of the major sources of information on the biology and veterinary aspects in the field. It stems from the founding premise of AAZV to share zoo animal medicine experiences. The Journal evolved from the long history of members producing case reports and the increased publication of free-ranging wildlife papers. The Journal accepts manuscripts of original research findings, case reports in the field of veterinary medicine dealing with captive and free-ranging wild animals, brief communications regarding clinical or research observations that may warrant publication. It also publishes and encourages submission of relevant editorials, reviews, special reports, clinical challenges, abstracts of selected articles and book reviews. The Journal is published quarterly, is peer reviewed, is indexed by the major abstracting services, and is international in scope and distribution. Areas of interest include clinical medicine, surgery, anatomy, radiology, physiology, reproduction, nutrition, parasitology, microbiology, immunology, pathology (including infectious diseases and clinical pathology), toxicology, pharmacology, and epidemiology.
