BRAF‐mutated malignant melanoma with chondrosarcomatous differentiation in inguinal nodal metastasis

Abstract

Abstract We report the case of a young woman who developed metastatic melanoma in the inguinal nodal region, which acquired chondrosarcomatous differentiation and preserved the BRAF mutation found in the primary tumor. The patient was treated with a BRAF/MEK inhibitor combination therapy (dabrafenib/trametinib), which was demonstrated to be effective and well‐tolerated.
