Trichuris vulpis (Roederer, 1761) is a geohelminth in the large intestine of wild carnivores, including domestic cats and occasionally humans. However, canine lymphoma, one of the most aggressive neoplasms in the small animal clinic, tends as a direct consequence of the loss of immunological response. Moreover, such parasite-related infections could develop into more serious conditions. In this study, we report a T. vulpis hyperinfection case in a canine affected by multicentric lymphoma. Physical examinations revealed lymphadenomegaly, haematochezia, and hind limb oedema. Despite the obtained treatment, the patient died. Macroscopic and microscopic examinations revealed congested lungs and legs, splenomegaly, lymphadenomegaly with leukocyte infiltration, and bloody large intestine mucosa with 528 adult T. vulpis specimens. Periodic coproparasitological examinations and specific antiparasitic drug applications are considered important, beyond preventive examinations for neoplasias, mainly in vulnerable patients such as older dogs.
