Cytoplasmic KIT localization in patterns II and III is significantly associated with what in dermal and subcutaneous MCT?

Explanation:
Cytoplasmic KIT localization in patterns II and III signals abnormal KIT signaling that drives more aggressive tumor behavior in dermal and subcutaneous mast cell tumors. This mislocalization correlates with higher tumor aggressiveness, leading to a greater likelihood of local recurrence after treatment, shorter disease-free intervals, and reduced survival. It reflects a biology where KIT-driven proliferation and survival are enhanced, rather than a pattern associated with better outcomes or no significance.
