Abstract
Neoplasia in the Gila monster (Heloderma suspectum) is not commonly investigated, and literature regarding the prevalence and type of neoplasms that affect this species is sparse. Gastrointestinal tract adenocarcinoma (GTA) in particular has only been reported twice in Gila monsters, once in the small intestine and once in the colon. In this case series, 50% (7/14) of the Gila monsters presented to the pathology service at Smithsonian's National Zoo and Conservation Biology Institute (SNZCBI) over the span of 26 yr (1997-2023) were found to have intestinal and/or colonic adenocarcinoma. The frequency of GTA reported in this collection likely represents a multifactorial etiology including geriatric age of specimens, chronic inflammation, gastrointestinal tract infection, and/or increased cognizance of the disease because of previous reports within the collection. An increased awareness of GTA in this species may lead to improved recognition of the disease.
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.
