We have studied 74 benign intramuscular angiomas in order to try and correlate clinical behaviour with histological appearances. The purpose was to find means of predicting those which would recur. Mean age at presentation was 17.6 years and 85% of the cases presented before age 30. The male: female ratio was 1.4:1. Anatomical distribution was 32% lower limb, 27% head/neck, 24% upper limb and 17% trunk. Reliable histological subclassification proved impossible since almost all lesions were of mixed type, albeit often with a single predominant vessel type--of which venous (42%) was the most common. Over 90% of the lesions contained a variably prominent adipocytic component. More than 50% of patients suffered local recurrence. Neither predominant vessel type nor anatomical localization correlated with recurrence, which was always due to incomplete excision.
我们研究了74例良性肌内血管瘤，试图将临床行为与组织学表现相关联。目的是找到预测哪些会复发的方法。就诊时的平均年龄为17.6岁，85%的病例在30岁之前就诊。男女比例为1.4:1。解剖分布为下肢32%，头/颈27%，上肢24%，躯干17%。可靠的组织学亚分类被证明是不可能的，因为几乎所有病变都是混合型的，尽管通常有一种单一的主要血管类型——其中静脉型（42%）最为常见。超过90%的病变含有不同程度突出的脂肪细胞成分。超过50%的患者出现局部复发。主要血管类型和解剖定位均与复发无关，复发总是由于切除不完全所致。
