Severe Adverse Reaction to Vemurafenib in a Pregnant Woman with Metastatic Melanoma.

Targeted therapies have drastically changed the management of metastatic melanoma and have shown encouraging results on tumour progression but are also known for their high rates of adverse reactions. In general, targeted therapies are contraindicated during pregnancy due to concerns about teratogenesis. For the BRAF V600 inhibitor vemurafenib, the available literature about the effects on human pregnancy is limited to a single case report.
