Red scrotum syndrome (RSS) is a rare dermatologic condition characterized by persistent erythema and analgesia of the male genitalia that cannot be attributed to contact or atopic dermatitis or acute or chronic infections. Treatment of RSS is challenging since it often fails to respond to corticosteroids, antifungals, antivirals, and antibiotics. Several reports described RSS patients who responded to gabapentin, pregabalin, and ?-adrenergic receptor blockers, suggesting a neuropathic etiology. Here we present a refractory RSS case with rapid clinical improvement on a combined carvedilol plus gabapentin therapy. We suggest that RSS manifestations are driven by neurogenic inflammation and that the efficacy of gabapentin/carvedilol relates to the suppression of the neuro-immuno-epidermal axis.
