Acquired progressive lymphangioma is rare and can histologically mimic well-differentiated angioendothelioma. In a 9-year-old boy with acquired progressive lymphangioma, we demonstrated that the neoplasm consists of at least a vascular component and a smooth muscle component. The presence of type IV collagen around many vascular channels suggests that an intermediate stage of differentiation between blood vessels and lymphatics may be present. Our findings indicate that acquired progressive lymphangioma is most likely a complex hamartoma composed of vascular channels and smooth muscle.
获得性进行性淋巴管瘤罕见，组织学上可酷似高分化血管内皮瘤。在一名患有获得性进行性淋巴管瘤的9岁男孩中，我们证实该肿瘤至少由血管成分和平滑肌成分组成。许多血管通道周围存在IV型胶原，提示可能存在血管和淋巴管之间的中间分化阶段。我们的研究结果表明，获得性进行性淋巴管瘤很可能是一种由血管通道和平滑肌组成的复杂错构瘤。
