Clinical application of imatinib mesylate in a case of feline cutaneous mast cell tumor: Clinical progress, histopathological, and immunohistochemical findings

초록

A 1.5-year-old neutered male domestic short hair cat was presented with multiple nodular mass, and suspected mast cell tumor on the surface of the right ear, accompanied by submandibular lymph node involvement. Histopathological Examinations and KIT (CD117) immunohistochemical staining was performed after the surgical resection of the entire right ear pinna. This patient was diagnosed with an anaplastic mast cell tumor with a diffuse positive cytoplasmic expression of KIT. Imatinib mesylate was prescribed after surgical resection; the patient presented without recurrence or metastasis for 2 years. Mild leukopenia was observed as the only side effect of imatinib mesylate during medication. ? 2017, Korean Society of Veterinary Clinics. All rights reserved.
