Fischer G, Papke Jr D
Semin Diagn Pathol . 2023 May; 40(4):246-257. PMID: 37156707
Cutaneous mesenchymal neoplasms are diagnostically challenging because of their overlapping morphology, and, often, the limited tissue in skin biopsy specimens. Molecular and cytogenetic techniques have identified characteristic gene fusions in...

Clin Cancer Res . 2022 Sep; 29(1):154-164. PMID: 36166093
Purpose: Overweight/obese (OW/OB) patients with metastatic melanoma unexpectedly have improved outcomes with immune checkpoint inhibitors (ICI) and BRAF-targeted therapies. The mechanism(s) underlying this association remain unclear, thus we assessed the...
