angiosarcoma arising in the breast following breast-conserving surgery with radiation for breast carcinoma

We report a case of angiosarcoma arising in the breast following breast-conserving surgery with radiation therapy for breast carcinoma. The patient, a 49-year-old postmenopausal woman, had undergone breast-conserving surgery for invasive ductal carcinoma of the left breast (pT2 pN0 M0 Stage IIA). Adjuvant radiotherapy (50 Gy with a booster dose to the tumor bed of 10 Gy) was then performed for the residual breast tissue and the patient was treated with hormone therapy (tamoxifen, 20 mg daily) for 5 years. She presented with skin erosion with bleeding 10 years after the initial operation. Incisional biopsy revealed angiosarcoma of the breast, and total mastectomy was subsequently performed. The patient was the treated with chemotherapy (weekly paclitaxel, 80 mg/m2 x cycles) and has remained well without evidence of local or distant recurrence.     

原发性心脏血管肉瘤合并肺部转移1例报告

<正>原发性心脏肿瘤很罕见,发病率为0.17%～0.33%,其中以良性肿瘤(黏液瘤和乳头状弹性纤维瘤)为主,占原发性心脏肿瘤的20%～40%^[1]。恶性者以肉瘤为主,而原发性心脏血管肉瘤非常罕见。目前本病遗传病理学特征仍不明确,亦无明确的标准治疗方案,临床治疗效果欠佳,治疗经验亦不足。现报告复旦大学附属中山医院收治的1例原发性心脏血管肉瘤合并肺部转移经化疗联合靶向治疗后获完全缓解病例,并探讨本病的临床特征、病理学特征及内科治疗进展。     

Pleuropulmonary angiosarcoma involving the liver,the jejunum and the spine,developed from chronic tuberculosis pyothorax: Multidisciplinary approach and review of literature

Pleuropulmonary angiosarcomas are very rare, with less than fifty cases reported in the literature. In most cases, the etiology is unknown but the presence of a chronic tuberculous pyothorax has been reported in several Asian case reports as a possible risk factor.     

Primary Epithelioid Sarcoma Manifesting as a Fungating Scalp Mass - Imaging Features and Treatment Options. A Case Report and Literature Review

Primary epithelioid sarcoma is an extremely rare malignancy of the scalp. To date, less than a dozen such cases have been reported in the literature. The diagnosis often is a challenge to both radiologists and clinicians. This is largely attributed to the lack of literature on the imaging features of scalp epithelioid sarcoma. In this report, we highlight the role of multimodality imaging in the diagnosis of primary scalp epithelioid sarcoma and review the epidemiology, imaging, treatment options, and prognosis of these malignant scalp tumors. Displaying a multilobulated morphology, heterogeneous enhancement, and restricted diffusion on MRI, these tumors typically show central degeneration with hemorrhage, necrosis, and calcification. Wide surgical resection and adjuvant radiotherapy are the mainstays of treatment for localized scalp tumors. Nevertheless, the prognosis of patients with distant metastases at diagnosis is extremely poor compared to those with local or regional diseases.     

Metastatic angiosarcoma of the scalp presented as posttraumatic subgaleal hematoma: The many faces of a diagnostic challenge

Angiosarcomas represent highly-aggressive malignant lesions of the endothelial cells of blood vessels, affecting mostly the elderly population, and usually located in the scalp or face. As cutaneous angiosarcomas often metastasize to the lung, they can manifest in various forms. We report a case of a 77-year-old male who presented after a posttraumatic blunt scalp lump that was initially diagnosed as infected subgaleal hematoma. This was later found to be an angiosarcoma. Further workup revealed that the tumor was invading the dura, with a rare pattern of mixed concomitant cystic and solid lung metastasis with ground-glass infiltrates. The patient underwent soft tissue reconstruction with split-thickness skin graft for the scalp lesion and palliative chemotherapy. We are discussing the common manifestations of scalp angiosarcomas and their potential pulmonary metastatic patterns. Also, a review of the differential diagnoses that may mimic cutaneous scalp angiosarcoma will be demonstrated.     

Computed tomography features of pulmonary metastases from angiosarcoma: Lessons learned from one case study

A distinctive feature of some angiosarcomas is that two or more atypical forms of pulmonary metastases may be detected concomitantly. In this case report, we present a 37-year-old man diagnosed with angiosarcoma of the neck, with extreme diversity of lung metastases on chest computed tomography (CT). We analyzed CT features of metastases and discussed possible reasons for their pleomorphism, as well as clinical implications of these findings.
