本病较为罕见,近年国内仅见报告一例。其组织发生是从血管周围的间质组织所发生的异位脂肪细胞而在真皮内形成的痣样病变。本病发生的时期可有二种:一是婴儿出生后即带有此痣,以后逐渐增大,名曰胎内发生型I另一种是出现于儿童或成年期,称之为晚发型。我们现在见到的一例,即属于晚发型,现报告如下:患者女,20岁。在来诊前2年发现右腰部有数个皮赘,生长缓慢,无任何自觉症状。惟于1981年7月半就诊前数日,忽觉其腰部的赘生物增长加速,並不时有疼痛感。检查见右腰部髂嵴处有5个园形或椭园形集簇的扁平结节,大者约2.6×1.1cm,小者约0.5×0.5cm,质地柔软,毫无压痛,表面松弛 This disease is relatively rare. In recent years, only one case has been reported in the country. Histogenesis occurs in the dermis from the ectopic fat cells that occur in the interstitial tissue surrounding the blood vessels. There may be two types of the disease: one is that the baby is born with this type of hemorrhoids, and then it gradually increases. The type I in the name of an abortion occurs in children or adulthood and is called an evening hairstyle. One case we see now is the late hairstyle. The report is as follows: The female patient is 20 years old. In the two years prior to the visit, several skin tags were found on the right waist, which grew slowly without any subjective symptoms. However, a few days before the July and mid-July 1981 visit, the growth of her neoplasms at the waist was suddenly accelerated, and there was a constant pain. Check that there are five flat or nodular clusters of flat nodules in the right lumbar region, which is about 2.6×1.1 cm for the larger and 0.5×0.5 cm for the smaller ones. The texture is soft, there is no tenderness, and the surface is loose.
