Epithelioid hemangioendothelioma (EHE) is a rare malignancy of vascular origin which can be primarily be seen in various tissues. EHE originating from the pleura is an even more uncommon subtype which may mimic mesothelioma and pleural carcinomatosis. The prognosis of pleural EHE is poor and there is no consensus on the optimal therapeutic approach.
A 39-year-old middle-eastern female presented with progressive dyspnea and left shoulder discomfort. Chest computed tomography scan revealed a left side pleural effusion and pleural thickening. Pleuroscopy was done and biopsies were taken which were positive for CD31, CD34, CK, factor 8-R-antigen, and vimentin. Patient was diagnosed with pleural epithelioid hemangioendothelioma (PEHE) and chemotherapy was started and underwent extrapleural pneumonectomy 7 months later. Unfortunately, the patient passed away 10 months after diagnosis due to disease complications.
Once PEHE is suspected in histology it can be confirmed with immunohistochemistry. Chemotherapy, surgery or a combination of both is currently used as the treatment but the standard treatment remains a question.
上皮样血管内皮细胞瘤(EHE)是一种罕见的血管源性恶性肿瘤,可原发于多种组织。起源于胸膜的 EHE 是一种更为罕见的亚型,可能类似于间皮瘤和胸膜癌病。胸膜 EHE 的预后较差,对于最佳治疗方法尚无共识。
一名 39 岁的中东女性,出现进行性呼吸困难和左侧肩部不适。胸部计算机断层扫描显示左侧胸腔积液和胸膜增厚。行胸腔镜检查并进行活检,CD31、CD34、CK、因子 8-R-抗原和波形蛋白阳性。患者被诊断为胸膜上皮样血管内皮细胞瘤(PEHE),并开始化疗,7 个月后行胸膜外全肺切除术。不幸的是,患者在诊断后 10 个月因疾病并发症去世。
一旦组织学怀疑为 PEHE,可通过免疫组织化学进一步证实。目前,化疗、手术或两者联合应用作为治疗方法,但标准治疗仍存在争议。
