Abstract

|
|
A tissue sample of a laryngopharyngeal mass from a 9-year-old male Dachshund dog was submitted to the Animal, Plant and Fisheries Quarantine and Inspection Agency for histopathologic evaluation. The mass measured was 3.1×3.0× 5.0 ㎝in diameter and was first detected by computed tomography. Histopathologically, the nodules consisted of large round and polygonal cells with abundant eosinophilic cytoplasm. The mitotic index was 1～3 per view under a high power field (400×). Immunohistochemically, tumor cells were positive for vimentin and desmin, but negative for cytokeratin, S-100, and α-Smooth Muscle Actin (α-SMA). Based on these findings, the tumor was confirmed as Laryngopharyngeal Rhabdomyosarcoma. To the best of our knowledge, this is the first case report in Korea.
