Simple Summary: Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer, with the head and neck region being the most common location. Perineural invasion (PNI), or the invasion of cancer into and around nerves, is a high-risk factor in cSCC associated with poor outcomes. The mechanisms of PNI in cSCC are poorly understood, but recent studies suggest that cross-communication between nerve components and cancer is a contributing factor. A better understanding of the mechanisms that promote PNI may lead to new therapies that improve outcomes in cSCC patients. Background/Objectives: Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer, with a lifetime risk of 14–20% that is rising every year. Although prognosis for cSCC is generally good, certain high-risk features of cSCC portend increased rates of nodal and distant metastasis, recurrence, and disease-specific mortality. One such high-risk factor is perineural invasion (PNI), which is broadly defined as the invasion of cancer into and around nerves. Compared to other high-risk factors, PNI presence is associated with the highest risk for locoregional and distant metastasis. Still, the mechanisms underlying the pathogenesis of PNI remain poorly understood. Recent studies suggest the migration and invasion of tumors into nerves is a result of complex molecular crosstalk within the tumor-nerve microenvironment, wherein the milieu of signaling molecules simultaneously promote neuronal growth and tumor cell invasion. Methods: Understanding the molecular and cellular mechanisms that promote PNI will lead to future developments of targeted therapies that may improve locoregional control and survival. Results/Conclusions: In our article, we aim to provide a comprehensive review of recent findings about the pathogenesis of PNI, clinical implications of PNI-positive disease in cSCC, available treatment modalities, and potential future therapeutic targets.
