Rectal irritative symptoms in cancer patients are often refractory to treat and exacerbate their quality of life. We experienced a peadiatric case of rectal irritative symptoms treated by Yokukansan. A 9 year-old boy developed rectal irritative symptoms as itching sensation in rectum caused by relapsed rhabdomyosarcoma in pelvis. Oral Yokukansan, which is common Japanese Kampo medicine for temper tantrum of children, was administered and relieved his symptoms. Yokukansan is known as adjuvant drug for neuropathic pain. It could be one of the adjuvant drugs for refractory symptoms in palliative care setting.
