血管球瘤是一种比较少见的良性肿瘤。1983年以来我们曾遇4例,报道如下:例1:女性,44岁,左拇指阵发性刺痛7年余,无外伤史。遇冷疼痛加重,遇热稍缓解。疼痛向前臂放射。检查,左拇指指甲增厚,形成纵行甲嵴,透过甲板见甲根部紫红色斑点。轻微触压肿瘤所在部位即激发剧痛,并向前臂放射,稍偏离瘤体则无压痛。 Glomerular tumor is a relatively rare benign tumor. Since 1983, we have met with 4 cases and reported as follows: Example 1: Female, 44 years old, with a staggering left cheek pain for more than 7 years, no history of trauma. In the case of cold, the pain worsened and the heat was slightly relieved. The pain radiates to the arm. Examination, thickening of the left thumb nails, formation of longitudinal nails, purple spots through the deck see the roots. A slight touch of the site of the tumor triggers severe pain and radiation to the front arm, leaving the tumor slightly without tenderness.
