Plain-English summary
A French bulldog in Japan was diagnosed with a serious parasitic infection called mesocestoidosis, which caused ongoing digestive issues. The dog had chronic enteritis, and after a biopsy, doctors found parasites in its intestines. Over the next few months, the infection spread to other parts of the body, including an inguinal mass and various organs. This case is notable as it is the first report of this type of infection affecting both the intestines and other organs in this region of Japan. Treatment details were not specified, but early diagnosis is crucial for managing such infections.

Abstract
This report describes a case of disseminated proliferative mesocestoidosis in a French bulldog from Aichi, Japan. In July 2023, the dog presented with chronic enteritis, and histological examination of the endoscopic biopsy specimen revealed parasites with suckers. Three months later, numerous tetrathyridia were detected in the inguinal mass. In April 2024, polymorphic tetrathyridia were detected on the visceral organs. These parasites were identified as Mesocestoides vogae (Cyclophylidea: Mesocestoididae) based on morphological features and sequence analyses. In Japan, M. vogae has only been reported in domestic dogs, with five cases of intestinal infection and one case of abdominal infection. This report is the first case of both intestinal and extraintestinal infections in the westernmost region of Japan.
