Primary pulmonary epithelioid angiosarcoma is an extremely rare malignancy. Herein, we report the case of an elderly Chinese patient with primary pulmonary epithelioid angiosarcoma. The 72-year-old man presented with a 1-month history of persistent hemoptysis and left chest pain and weight loss of 3 kg. A chest computed tomography (CT) scan revealed two masses (maximum size 3.0 cm × 2.0 cm and 0.8 cm × 0.5 cm) in right lower lobe. We performed a left thoracotomy for tumor resection. Pathological examination showed that there was a significant amount of hemorrhage, fibrinous exudates, degeneration, and necrosis. With immunohistochemical analysis, tumor cells had strong expression of CD34, FLI-1, vimentin. Morphological and immunohistochemical findings supported the diagnosis of epithelioid angiosarcoma.

| > Introduction|| |
Epithelioid angiosarcoma is an extremely rare malignant vascular tumor with a very poor prognosis. Most angiosarcomas occur in skin, spleen, liver, breast, heart, bone, and gastrointestinal tract have been well-documented. Primary epithelioid angiosarcoma of the lung is extremely rare, and only a few primary cases have been reported., Here, we report a case of primary epithelioid angiosarcoma of the lung with reviewing the relevant literature.
| > Case Report|| |
A 72-year-old man, with a 1-month history of persistent hemoptysis and left chest pain, was admitted to our hospital in May 2014. He complained about shortness of breath on exertion and weight loss. Computed tomography (CT) scan revealed a 3.0 cm oval-shaped mass in right lower lobe [Figure 1]. His medical history included cerebral hemorrhage with left ineffective limbs, and he had 50 years of smoking history. At admission, the patient presented with pulse rate of 84 beats/min, blood pressure of 154/71 mm Hg, and oxygen saturation of approximately 97%. We preoperatively diagnosed lung malignant tumor.
The patient underwent a tumor resection with thoracotomy under general anesthesia. By surgical exploration, two masses of sized 3.0 cm × 2.0 cm × 1.8 cm and 0.8 cm × 0.5 cm× 0.5 cm were observed in dorsal segment of right lower lobe. The masses extensively adhered to the parietal pleura with obscure boundaries. The surface of the masses exhibited calcification, and the tissue appeared hard and thickened. Wedge resection was done for frozen pathology, and the result showed malignant tumor; we decided to the left lower lobe and lymph nodes resection.
The postoperative course was uneventful. The patient recovered with no major complication and was discharged from the hospital 10 days after the operation. Pathological examination revealed that the tumors mainly consisted of fibrinous exudates and hemorrhagic and degenerated necrotic tissue, in addition to a small amount of hyperplastic and degenerated fibrous connective tissue. Immunohistochemical analysis showed tumor cells had strong expression of CD34, FLI-1, vimentin [Figure 2].

Neither postoperative radiotherapy nor chemotherapy was performed in the patient due to his old age. Currently, 1 year following surgery, the patient is alive and exhibits no evidence of disease recurrence.
| > Discussion|| |
Angiosarcoma is a rare malignant tumor derived from vascular endothelium, accounting for only 1–2% of all soft-tissue sarcomas., Epithelioid angiosarcoma involving the lung is a rare disorder with low incidence, especially its primary form. Pulmonary angiosarcomas are usually the result of metastatic disease (pulmonary metastases occur in 60–80% of cutaneous and cardiac angiosarcomas).
Epidemiologically, there is no gender priority and the average age of occurrence is 45 years. Predisposing factors are unknown, may be related to certain stimulating factors such as lucite plombage, chronic empyema, and tuberculous pyothorax. Patients with primary angiosarcoma can present with chest pain, hemoptysis, dyspnea, cough, and weight loss. However, up to 20% of cases are asymptomatic and are detected as an incidental finding at autopsy.,
The common radiographic presentation may be multiple peripheral pulmonary nodules, solitary mass with adjacent alveolar pattern and/or variable degree of consolidation, and ground-glass opacity. However, neither chest radiography nor CT scan is able to differentiate epithelioid angiosarcoma of the lung and any other pulmonary malignant neoplasms.
Definitive diagnosis is made on the basis of histopathological and immunohistochemical findings. The microscopic feature is always misleading except some subtle clues such as red blood cells containing intracytoplasmic lumina. Immunohistochemically, the neoplastic cells showed reactivity for endothelial cell markers (CD31, CD34, factor VIII, FLI-1, and Ulex europaeus agglutinin I), epithelial markers (cytokeratins and sometimes epithelial membrane antigen), and vimentin.
Treatment options for pleural angiosarcoma include surgery, chemotherapy, and radiation. Surgery is the best treatment for patients with localized lesions. Vascular embolization can decrease the size of the tumor and control bleeding, and it may be performed before surgery. The effect of radiation therapy is very poor, and the curative effect of chemotherapy needs further evaluation. Wilson et al. have mentioned complete radiographic response of disease by a chemotherapeutic combination of gemcitabine and taxotere. Prognosis of pulmonary angiosarcoma has been shown to be poor with almost all patients dead within months of initial presentation. Our experience with this case suggests that comprehensive and sufficient sample collection and meticulous histological examination are required for accurate diagnosis of this malignancy.
