One of the characteristics of herpes zoster lesions is their distribution along the peripheral nerves, e.g., if they invade the sacrococcygeal nerve, they can grow on the labia, scrotum, perianal area, and other intimate areas. This lesion is caused by varicella-zoster virus infection and is characterized by clusters of herpes and neuralgia distributed in bands along the peripheral nerves. When the sacrococcygeal nerve is invaded, the lesions are distributed along and around the sacrococcygeal nerve, and herpes can appear in such areas as the perianal area, the labia majora and minora in women, and the scrotum in men, which are often referred to as the intimate areas. Before the onset of the disease, there are usually fever, fatigue, local lymph node swelling and pain, neuralgia and other prodromal symptoms. Typical lesions are papules, papules and blisters, and there may be hyperpigmentation, which is common in the chest and abdomen, and may also involve the upper and lower limbs and perineum. When the above symptoms occur, it is recommended to go to the hospital for consultation and targeted treatment after a clear diagnosis.
