Mast cell tumors (MCTs) are among the most common skin tumors in dogs. They range from low-grade, easily cured lesions to aggressive, metastatic cancers — and their appearance does not reliably predict grade. Accurate grading and staging determine whether surgery alone is curative or whether adjunct therapy is needed.

Grading (Patnaik vs Kiupel systems) affects prognosis dramatically; incomplete surgical margins and metastasis assessment require specialist review. A Grade 2 tumor under the Patnaik system is actually a heterogeneous group — Kiupel's two-tier system more accurately predicts behavior. Incomplete excision of a high-grade MCT without adjunct therapy is a serious management error.
Accurate grade confirmation, lymph node staging, adjunct therapy recommendation, and re-excision vs radiation vs medical management decision. An oncologist evaluates surgical margins histopathologically, assesses regional lymph nodes, and determines whether imatinib (Palladia) or other systemic therapy is indicated based on grade and c-KIT mutation status.
