INTRODUCTION: Merkel cell carcinoma (MCC) is a very rare and aggressive neoplasm. Due to its rarity, therapeutic guidelines are not well established, especially for regionally advanced disease. Hyperthermic isolated limb perfusion (HILP) with Melphalan and either with or without tumor necrosis factor-alpha (TNF-alpha) is becoming more common in clinical practice, ...
