Immunosuppressed patients are at increased risk of local recurrence, metastasis, and disease specific death from cutaneous squamous cell carcinoma.

It is well established that immunosuppressed patients are at increased risk for poor outcomes (PO) from cutaneous squamous cell carcinoma (cSCC), including local recurrence (LR), nodal metastasis (NM), distant metastasis (DM), and disease-specific death (DSD). Defining PO risk is challenging but may be beneficial in guiding management. We aimed to define PO risk factors and evaluated their importance in immunosuppressed versus immunocompetent patients.

Current concepts and approaches to merkel cell carcinoma.

Merkel cell carcinoma (MCC) is an aggressive and rare cutaneous cancer of the mechanoreceptor unit of the skin with a neuroendocrine origin. MCC incidence has been on the rise over the past two decades. Risk factors include old age, chronic UV exposure, and immunosuppression.
