Abstract

Background

The BRAF-inhibitor vemurafenib, used in patients with metastatic melanoma, induces multiple cutaneous side-effects.

Objective

The aim of this work was to evaluate the development of palmoplantar fibromatosis in a population of patients treated with the BRAF inhibitor vemurafenib.

Methods

Between April 2011 and February 2013, we initiated a treatment with vemurafenib in 53 patients with an unresectable stage IIIC or stage IV melanoma. The patients were followed-up on a regular base to monitor possible side-effects.

Results

A plantar or palmar fibromatosis was observed in five of 53 patients treated with vemurafenib. In four of these patients other risk factors for the development of palmoplantar fibromatosis were absent.

Conclusion

The BRAF-inhibitor vemurafenib might induce palmoplantar fibromatosis.
