Lymphangioma circumscriptum is a benign disorder of lymphatic channels. The pathology consists of a collection of subcutaneous lymphatic cisterns communicating through dilated channels with superficial clusters of vesicles. The most common symptom is recurrent oozing of clear fluid. Management consists of wide excision, assuring free lateral and deep margins by frozen-section analysis. Involved margins have been shown to increase the recurrence rate. Laser vaporization has been used recently with relatively good results. The etiology of this lesion is unclear; however, lymphatic obstruction has been suggested as a possible cause in occasional cases. Two cases of vulvar lymphangioma circumscriptum have been reported previously in the literature, both arising in elderly women after radiation therapy for squamous cell carcinoma of the cervix. We present the third case, arising in a 42-year-old woman with no previous surgery or radiation.
局限性淋巴管瘤是一种淋巴管的良性疾病。其病理表现为皮下淋巴管池的集合，这些淋巴管池通过扩张的通道与浅表的水疱群相通。最常见的症状是清亮液体反复渗出。治疗方法包括广泛切除，通过冰冻切片分析确保切缘外侧和深部无肿瘤组织。切缘阳性已被证明会增加复发率。最近使用激光汽化治疗取得了相对较好的效果。该病变的病因尚不清楚；然而，在少数情况下，淋巴管阻塞被认为是可能的原因。此前文献中曾报道过两例外阴局限性淋巴管瘤，均发生于老年女性，她们曾接受过宫颈癌鳞状细胞癌的放射治疗。我们报告第三例，发生在一名42岁女性，既往无手术或放疗史。
