■血管恶性肿瘤分为良性血管瘤,恶性血管肉瘤,和中间恶性肿瘤。逆行血管内皮瘤(RH)是最初诊断为中间恶性肿瘤的罕见诊断之一。
■在此案例报告中,我们报告了一例罕见的RH,当地的侵略性,在不寻常部位表现为恶性潜能的血管肿瘤。这种软组织肿瘤的观察最多的位置是四肢的皮肤和皮下组织;然而,这个病例是在一个叫做胸膜的不寻常部位观察到的,这是与这种肿瘤有关的罕见事件。血管和内皮起源的细胞表面标志物如CD31和ERG的存在以及活检轮廓上内皮通道的hobnail外观的存在支持了肿瘤的血管起源;临床特征和影像学研究进一步证实了RH的诊断。
■在此案例报告中,我们强调了一例罕见的RH病例,其来源不寻常.RH是一种血管肿瘤;这种血管肿瘤的常见部位是四肢的皮肤和皮下组织;然而,在这种情况下,该网站异常不同,那是左肺的胸膜.
UNASSIGNED: Vascular malignancies are categorized into benign hemangiomas, malignant angiosarcomas, and tumors of intermediate malignancy. Retiform hemangioendothelioma (RH) is one of the rare diagnoses belonging to the class of intermediate malignancies that was initially diagnosed.
UNASSIGNED: In this case report, we have reported a rare case of RH, a locally aggressive, vascular tumor of malignant potential presenting at an unusual site. The most observed locations of this soft tissue tumor are skin and subcutaneous tissues of extremities; however, this case of RH was observed in an unusual site called pleura, which is a rare occurrence related to this tumor. The presence of cell surface markers like CD31 and ERG of vascular and endothelial origin and the presence of hobnail appearance of endothelial channels on the biopsy profile supported the vascular origin of the tumor; the clinical features and imaging studies further confirmed the diagnosis of RH.
UNASSIGNED: In this case report, a rare case of RH with an unusual site of origin was highlighted. RH is a vascular neoplasm; commonly observed sites of this vascular tumor were skin and subcutaneous tissue of the extremities; however, in this case, the site was unusually different, which was the pleura of the left lung.
