Hemophagocytic lymphohistiocytosis (HLH) has been reported rarely with BRAF/MEK inhibitor combinations, including dabrafenib/trametinib. Postmarketing pharmacovigilance analyses evaluating outcomes associated with dabrafenib/trametinib-induced HLH are also lacking. Herein, we report a case of dabrafenib/trametinib-induced HLH in a patient with metastatic melanoma.

Designation of activating CSF3R mutations as a defining genomic abnormality for CNL has led to increased recognition of the disease. However, the natural history of CNL remains poorly understood with most patients reported being of older age, lacking germline data, and having poor survival, in part due to transformation to acute leukemia.

Rapidly proliferating leukemic cells cause symptoms and increase the risk of infection. While individuals may initially benefit from supportive measures, disease-directed therapy may ultimately be required for symptom management, even at the end of life, although this may also inadvertently increase symptom burden.

Graft versus leukemia (GVL) is a critical component of successful transplantation and involves donor cells eradicating residual leukemia within the recipient. Graft versus host disease (GVHD) by contrast is a common complication of the transplantation process in which donor cells identify the recipient's various organ systems as foreign, thereby leading to a multitude of organ toxicities that can be described as autoimmune in nature.

The overall risk of morbidity and mortality (M&M) in MM patients due to COVID-19 infection is unclear with various studies suggesting case fatality rate of 22% to 29%. Additionally, most of these studies did not stratify patients by their molecular risk profile.

It carries a poor prognosis secondary to poor response to therapy or rapid disease relapse. Currently there are no randomized trials to guide treatment.
