Alopecia areata (AA) is a nonscarring alopecia driven by autoreactive cytotoxic CD8 T cells against hair follicle antigens. With an unpredictable clinical course, which can include alopecia totalis and universalis, AA can be debilitating to patients’ quality of life. Historically, glucocorticosteroids, cyclosporine, methotrexate, and azathioprine were used off-label for non-targeted immunosuppre …

When curative surgery and radiotherapy are contraindicated, systemic agents targeting the hedgehog signaling pathway are invaluable options for this subset of adult patients with locally advanced BCC (laBCC). Vismodegib and sonidegib are oral options with similar efficacy and side effect profiles. With the absence of head-to-head comparis … 
Generalized pustular psoriasis (GPP) is a rare, autoinflammatory condition, with acute, severe flares of diffuse sterile pustules and systemic symptoms that can be life-threatening. Historically, cyclosporine, methotrexate, retinoids, and biologics modulating the interleukin-17 (IL-17), IL-23, and tumor necrosis factor α pathways have been used off-label for management.1 Aberrant IL-36 signaling …
