Vascular transformation of sinuses (VTS) in lymph node has been infrequently reported. We present a case of incidental VTS in bilateral cervical nodes discovered at the time of operation for tongue cancer.
Standard histopathologic review was undertaken.
In this case, a spectrum of varied vasoformative patterns involving lymph nodes in either a pan-nodal or localized fashion were identified. The hilum was occupied by smooth muscle proliferation and adipose tissue. Two nodes also displayed similar features of angiolipomatous hamartoma. No metastatic carcinoma was found in lymph nodes with VTS.
This case suggests that lymphovenous congestion and distention represented the major cause through which VTS developed.
淋巴结内的窦状血管转化（VTS）鲜有报道。我们报告一例在舌癌手术时偶然发现的双侧颈部淋巴结VTS病例。
进行标准组织病理学检查。
在该病例中，发现一系列不同的血管形成模式，以全淋巴结或局部方式累及淋巴结。淋巴结门部被平滑肌增生和脂肪组织占据。两个淋巴结还表现出血管脂肪瘤样错构瘤的相似特征。VTS的淋巴结中未发现转移癌。
该病例提示，淋巴静脉充血和扩张是VTS发生的主要原因。
