Vemurafenib-induced neutrophilic panniculitis in a child with a brainstem glioma.

Neutrophilic panniculitis is a rare adverse effect of therapy with selective BRAF inhibitors. We report a case of neutrophilic panniculitis in a 15-year-old girl receiving treatment with vemurafenib for a brainstem glioma. Clinicians should be aware of this rare but important side effect of vemurafenib. This is the first report of neutrophilic panniculitis in a child treated with vemurafenib.
