Benign vascular tumors arising primarily in lymph nodes are rare. The importance of identifying these entities is to avoid misdiagnosing them as malignant vascular tumors, which occur more often in lymph nodes. Hemangioma is a benign nodal vascular tumor, but its occurrence in lymph nodes is extremely rare. Hemangiomas can occur at any age, mostly in females. It is usually asymptomatic, affects only one node, and does not recur. Four histologic types of hemangioma have been identified: capillary/cavernous, lobular capillary, cellular, and epithelioid. This review highlights the key features of previously reported cases and discusses the differential diagnosis.
主要发生在淋巴结的良性血管肿瘤很少见。识别这些实体的重要性在于避免将其误诊为更常见于淋巴结的恶性血管肿瘤。血管瘤是一种良性淋巴结血管肿瘤，但在淋巴结中极为罕见。血管瘤可发生于任何年龄，多见于女性。通常无症状，仅累及一个淋巴结且不复发。已鉴定出血管瘤的四种组织学类型：毛细血管/海绵状、小叶状毛细血管、细胞状和上皮样。本综述强调了以前报道病例的关键特征，并讨论了鉴别诊断。
