Presentation with multiple cutaneous MCTs occurs in 9–21% cases (Murphy et al. 2004, 2006; Mullins et al. 2006). Boxers, Golden retrievers, and Labrador retrievers have been identified as breeds at increased risk of developing multiple cutaneous MCTs (Thamm et al. 1999). Older dogs are more likely to present with multiple cutaneous MCTs (Kiupel et al. 2005). Multiple cutaneous MCT presentation was originally considered a poor prognostic sign and is designated stage III on the WHO staging scheme. Several studies have demonstrated that there is no difference in survival times for single vs. multiple cutaneous MCT (Murphy et al. 2006; Thamm et al. 1999). Dogs with multiple cutaneous MCTs have a low rate of metastasis and a good prognosis for long‐term survival with adequate excision of all MCTs (Mullins et al. 2006). Each individual MCT should be treated as a de novo lesion.
