Summary
A rare adenosquamous carcinoma was found in a cat
Area of Science:
- Veterinary Pathology
- Oncology
- Comparative Medicine
Background:
- Esophageal tumors are uncommon in domestic cats.
- Adenocarcinoma and adenosquamous carcinoma of the esophagus have not been previously reported in feline species.
Observation:
- An eight-year-old, castrated male, Japanese domestic cat presented with esophageal carcinoma.
- Histological examination revealed two distinct neoplastic growth patterns: squamous cell carcinoma and adenocarcinoma.
Findings:
- Immunohistochemical analysis confirmed distinct cellular characteristics for both neoplastic components.
- The tumor was diagnosed as a rare adenosquamous carcinoma, a type previously undocumented in cats.
Implications:
- This case expands the known spectrum of esophageal neoplasms in cats.
- Highlights the importance of thorough histological and immunohistochemical evaluation for accurate diagnosis of complex feline tumors.
