Auntie Tang is very distressed in the past six months, the left index finger inexplicably painful situation, but also, the onset of pain seems to be out of nowhere; usually this finger no discomfort, but sometimes the finger nail cover to touch a hard thing will be a sudden pain to jump up! After several times, she couldn’t take it anymore and went to the hospital to see the medical and surgical departments, but she couldn’t tell the reason. However, the pain would continue to trigger once in a while, and there were painful episodes when she touched cold water. Later, she was so scared of the pain that she carefully hid her left hand in her pocket every day, and no one was allowed to touch it! What is this strange disease? What is this strange disease? The strange disease that causes this typical pain symptom is subxiphoid hemangioblastoma. It is a small mass-like lesion under the nail, sometimes visible through the nail as a localized raised, light purple or dark blue nodule, a few millimeters in diameter. The typical symptom is severe localized pain: there is often significant tenderness and spontaneous pain, and in severe cases the tenderness is intense radiating pain, but occasionally there is no pain, characterized by no pain without touching, but pain is obvious when stimulated by heat, cold or pressure. Clinically, experienced osteopathic surgeons will use the round tip of a large head needle to accurately point out the focal area of the hemangioblastoma. In patients with prolonged disease, bone resorption of the underlying phalanges may sometimes be seen on radiographs. High-resolution magnetic resonance imaging is useful to assist in localizing the tumor prior to surgery. Surgical excision of subxiphoid hemangioblastoma is the most effective treatment for this disease and has a good prognosis.
