英文摘要：

A 81-year-old male presented with two-month history of erythema, itching and burning sensation on the bilateral inguinal regions and scrotum. Treatments with topical corticosteroids and antimycotics did not improve the lesion.Dermatological examination revealed well-demarcated erythema on the bilateral inguinal regions and scrotum without noticeable scaling or other abnormalities. Biopsy of the lesion showed normal epidermis,remarkable superficial telangiectasias and perivascular infiltration of inflammatory cells. A diagnosis of red scrotum syndrome was made. Erythema and burning sensation almost completely disappeared after two-week treatment with pregabalin 75mg twice daily. No recurrence occurred during the period of two-month follow-up.
