Abstract
Squamous cell carcinoma (SCC) is a malignant epidermal tumor. Biologic behavior and metastasis rate vary according to species and tumor location. The goal of this study was to report the occurrence and behavior of an oral SCC in a Tapirus terrestris treated with electrochemotherapy. The tapir was anesthetized for two electrochemotherapy sessions, six months apart, with intralesional cisplatin (0.25 mL/cm3) and VetCP 125TM electroporator. Side effects were minimal. Because of tumor relapse, onset of joint disorders, and poor prognosis, the animal was euthanized and submitted to necropsy, followed by histopathological and immunohistochemical analyses. Electrochemotherapy significantly improved the tapiŕs life quality. Tumor bleeding resolved, and food uptake was improved. Necropsy demonstrated tumor invasion in adjacent soft tissues and bones and submandibular lymph nodes with multiple areas of metastasis. Overall survival time of 35 months was achieved, with good life quality. Histopathologic characteristics were more aggressive in the relapsed tumor.
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.
