Hemangioblastoma is a small benign hemangioma that occurs in young and middle-aged people, slightly more often in women than in men. They are mostly solitary, but can also be seen in multiple cases. They are most often found in the skin or subcutaneous tissue of the extremities, especially under the nail beds of the hands and feet. They are small in size, rarely exceeding 0.5 cm, and are well defined with a pale red or purple-blue surface. Classification: Angioglobulomas are neoplastic organisms formed by the proliferation of tissues that make up the vascular bulb. They can be classified into three types based on the predominant component: (1) angiomatous; (2) cellular; and (3) neurological. Light microscopy is mainly composed of patches of vascular bulb cells, vascular structures and smooth muscle structures with pale eosinophilic or hyaline cytoplasm. The nuclei are round or oval in shape and located in the center of the cells. The tumor may contain connective tissue, smooth muscle tissue and unmyelinated nerve fibers. The most common site of growth is the nail bed of the finger, but it can also occur in any other parts of the body.
Angioblastoma can also occur on the arms of the fingers and other places. Damage to the fingers and toes is most common in women, and in other parts of the body, it is more common in men. It is a small blood cell-like dark red or purple-blue color. Clinically, the lesions resemble blue blister nevi and are usually widespread on the trunk and can be clustered in dozens of lesions. 2. Severe local pain There is often significant tenderness and spontaneous pain, sensitive to cold, the affected limb immersed in cold water immediately causes severe pain, can be relieved after warming. The pain increases at night when eating acidic substances and mood swings. 3, with the round head of a large-headed needle can point pressure out of the site if the growth in other parts of the subcutaneous, may also touch the painful subcutaneous nodules or see local skin darkening. Treatment: Surgical excision is the only treatment for this disease. After excision of the nail, the mucosa of the nail bed is cut open to reveal the neoplasm, and the nail is completely excised by peeling off the nail by the envelope, and good results can be obtained.
