(A) MRI/EUS before and (B) after EUS-guided ethanol lavagae of a small mucinous cystic lesion with atypical cytology results and cyst fluid CEA (500 ng/mL). Surgical resection of the post-lavaged cyst was performed and demonstrated a benign lesion with partially ablated cyst epithelium. (C) (bottom left) Diff-Quick stain, 200×. (D) (bottom right): H&E stain, 20×.

(A) Endoscopic ultrasound-guided device-based pancreatic tumor ablation. (B) Gross pathologic specimen, demonstrates a firm, beige 1.0 cm area corresponding to the treatment site. (C) Histopathology specimen: (H&E, orig. mag. 64×) 48 hours after RFA demonstrates a sharp demarcation between coagulated (C) and untreated pancreas (P). A 1 to 2 mm watershed zone of an early inflammatory response (I) surrounds the coagulated tissue.
