RESUMEN

This case report highlights the adverse effects of pazopanib, a vascular endothelial growth factor receptor inhibitor, on wound healing after Mohs surgery. A 79-year-old male with metastatic renal cell carcinoma of the lung, on 600 mg daily pazopanib, underwent Mohs surgery for a nodular basal cell carcinoma on his right leg. Despite multiple wound care strategies, his wound deteriorated over 4 months. Discontinuing pazopanib resulted in rapid wound closure within 2 months. However, metastatic lung nodules grew, prompting treatment with immune checkpoint inhibitors, nivolumab, and ipilimumab, which were discontinued due to complications. Near-complete wound healing was observed prior to reintroducing pazopanib (6 months after initial discontinuation), which again led to wound deterioration. Pazopanib negatively impacts wound repair by inhibiting cell proliferation and angiogenesis. Depending on the malignancy or tumor, cessation of pazopanib, or switching to a course of immune checkpoint inhibitors may be warranted perioperatively.
