This report describes the clinical and paraclinical findings of generalized megaesophagus with a possible contribution of toxocariasis in a kitten. A 2-month-old female cat was referred with chief complaints of lethargy, hyporexia, dyspnea, and vomiting/regurgitation. Physical examination of the kitten revealed bradycardia, bradypnea, hypothermia, dehydration, and lung crackles. The most notable laboratory results were leukopenia with severe toxic changes in neutrophils. Radiographic findings were compatible with the diagnosis of generalized megaesophagus. Despite supportive measures, the kitten died the next day. Necropsy revealed diffuse esophageal dilation and <i>Toxocara</i> spp. roundworms in the stomach and duodenum. Histopathology showed an ascarid larva in the esophagus, necrosis and metaplasia in the pylorus, and absence of villi and Brunner's glands in the duodenum. Based on the morphological identification of the adult gastrointestinal nematodes, the final diagnosis was generalized megaesophagus of unspecified classification concurrent with toxocariasis. However, the exact cause of death could not be established. Although respiratory abnormalities raised suspicion of a pulmonary complication, pneumonia was not confirmed. We hypothesized that toxocariasis may have contributed to esophageal dysfunction in this kitten through potential mechanisms such as vomiting, gastrointestinal obstruction, or neurological involvement; however, these mechanisms could not be directly demonstrated. Therefore, parasitic diseases, including toxocariasis, may be considered among potential differential diagnoses or contributing conditions in young cats presenting with megaesophagus, particularly when concurrent gastrointestinal parasitism or related complications are identified. Further studies are required to clarify the possible relationship between toxocariasis and esophageal dysfunction.</p>","PeriodicalId":37339,"journal":{"name":"Case Reports in Veterinary Medicine","volume":"2026 ","pages":"9504866"},"PeriodicalIF":0.0,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13673221/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149216971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiography revealed a large soft-tissue opacity in the middle coelomic cavity, with caudodorsal displacement of the intestinal loops and compression of the thoracoabdominal air sacs. Ultrasonography identified a very large hepatic mass with granular and mixed echogenicity occupying most of the coelomic cavity. The bird was euthanized at the owner's request because of the severity of the lesion and poor clinical condition. At necropsy, the liver was markedly enlarged, dark red to reddish-brown, mottled and occupied most of the coelomic cavity. Histologically, the hepatic parenchyma was extensively replaced by densely packed mononuclear neoplastic cells, with effacement of hepatic cords and hepatocellular necrosis. No neoplastic infiltration was identified in the examined tissues, including spleen, kidney, intestine, lung, and heart; therefore, the liver was the only confirmed site of lymphoma among the examined tissues in this case.

This report describes the successful management of a large postsurgical wound in an 8-year-old spayed mixed-breed female dog following wide-margin nodulectomy of a dorsal thoracic mass initially diagnosed cytologically as a suspected liposarcoma. Although primary closure using an H-plasty reconstructive technique was initially performed, progressive central necrosis developed at the surgical margins during the postoperative period. On postoperative Day 3 (POD 3), the wound exhibited tissue necrosis and serosanguineous exudation, necessitating management by second-intention healing. Following surgical debridement, the wound measured approximately 143 cm² and was subsequently managed using a multimodal advanced wound care protocol based on the principles of the TIME framework, combined with tie-over dressing fixation, advanced wound dressings, fluorescence biomodulation, electrobioregulation, and topical regenerative therapies. Histopathological examination of the excised tissue ultimately revealed chronic-active pyogranulomatous panniculitis with abundant fibrosis, ruling out the initial suspicion of neoplasia. Progressive wound contraction, granulation tissue formation, and epithelialization were observed throughout the treatment period, with serial measurements demonstrating a reduction from 143 cm² to complete closure over approximately 16 weeks. No evidence of local infection, recurrent tissue necrosis, wound dehiscence, or systemic complications was detected during follow-up. Complete wound healing was achieved with satisfactory functional and cosmetic outcomes, without the need for additional reconstructive surgery. This case highlights the potential clinical value of a multimodal, individualized approach to managing extensive, complicated wounds in dogs. It suggests that sequentially integrating the TIME framework, tie-over fixation, fluorescence biomodulation, and electrobioregulation may offer a useful therapeutic alternative when conventional reconstructive techniques are unsuccessful.</p>","PeriodicalId":37339,"journal":{"name":"Case Reports in Veterinary Medicine","volume":"2026 ","pages":"6722904"},"PeriodicalIF":0.0,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13548134/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148907567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical records noted localized purulent lesions and abscesses in 58% of cases.
