Pulse Dosing Vismodegib Therapy as an Effective Treatment of Basal Cell Carcinoma: A Case Report

Abstract

Basal cell carcinoma (BCC) is a common nonmelanoma skin cancer, frequently present on the face and head. BCC is linked to the Sonic Hedgehog (Shh) signaling pathway. Mutations within the Shh signaling pathway, involving the activation of the ligand-independent pathway by the Smoothened (Smo) protein, can lead to unregulated proliferation of basal cells, resulting in BCC. Vismodegib, a hedgehog pathway inhibitor, is a chemotherapy drug approved for targeting the Shh signaling pathway. We herein report a presentation of nodular BCC in a Caucasian female who was treated with Vismodegib. This case highlights the effectiveness of pulse dosing treatment to minimize side effects.
