Primary hepatic angiosarcoma: a clinicopathological analysis of nine cases / 中华病理学杂志

Objective: To investigate the clinical manifestations, histomorphology, and differential diagnosis of primary hepatic angiosarcoma. Methods: Nine cases of primary hepatic angiosarcoma diagnosed in the Department of Pathology, the First Affiliated Hospital of Nanjing Medical University from January 2014 to December 2021 were collected, including biopsy and surgical specimens. The histomorphology, clinical, and radiologic findings were analyzed. The relevant literature was also reviewed. Results: There were six males and three females, aged 30 to 73 years (mean 57 years). Grossly, the growth pattern of the tumor was classified as either mass formation or non-mass formation (sinusoidal). Microscopically, the mass-forming primary hepatic angiosarcoma were further subdivided into vasoformative or non-vasoformative growth patterns; and those non-vasoformative tumors had either epithelioid, spindled, or undifferentiated sarcomatoid features. Sinusoidal primary hepatic angiosarcoma on the other hand presented with markedly dilated and congested blood vessels of varying sizes, with mild to moderately atypical endothelial cells. Follow-up in all nine cases revealed 8 mortality ranging from 1 to 18 months (mean 5 months) from initial diagnosis. One patient was alive with disease within a period of 48 months. Conclusions: Primary hepatic angiosarcoma is a rare entity with a wide spectrum of histomorphology, and often misdiagnosed. It should be considered when there are dilated and congested sinusoids, with overt nuclear atypia. The overall biological behavior is aggressive, and the prognosis is worse.

Proliferación vascular atípica mamaria inducida por radioterapia / Atypical vascular proliferation of the breast induced by radiation

La proliferación vasculara típica mamaria inducida por radioterapia es una proliferación angiomatoide que aparece sobre la piel previamente irradiada por el tratamiento conservador de un carcinomademama. Se presenta el caso de una paciente de 58años que consultó por la aparición de múltiples pápulas purpúricas milimétricas en la mama derecha. Había recibido radioterapia y cuadrantectomía por un carcinoma intraductal 5años antes y estaba medicada con tamoxifeno. El análisis histópatológico e inmunohistoquímico informó: "Proliferación vascular atípica inducida por radiación, variedad atípica inducida por radiación, variedad linfática". Se adoptó una conducta expectante, con seguimiento estrecho.

Atypical vascular proliferation of the breast induced by radiation is an angiomatoid proliferation that appears on previously irradiated skin by the conservative treatament of a breast carcinoma. We present a 58-year-old female patient who consulted for multiple millimeter purpuric papules in the right breast. She received radiotherapy and quadrantectomy for an intraductal carcinoma 5 years before. She is currently on tomoxifen. The histopathology and immunohistochemistry reported atypical vascular proliferation induced by radiation, lymphatic variety. Watchuful waiting is adopted with close monitoring.

Clinical Courses of Primary Hepatic Angiosarcoma: Retrospective Analysis of Eight Cases / 대한소화기학회지

BACKGROUND/AIMS: Hepatic angiosarcoma, a rare and aggressive liver malignancy, is difficult to diagnose because of a lack of specific clinical features. The clinical and radiological features of patients with histologically confirmed hepatic angiosarcoma were examined. METHODS: Among 2,336 patients diagnosed with primary hepatic carcinoma at Keimyung University Dongsan Medical Center (Daegu, Korea) between May 2002 and February 2012, eight (0.03%) with histologically confirmed primary hepatic angiosarcoma were included. The patterns of disease diagnosis, tumor characteristics, treatment responses, and prognoses were reviewed retrospectively. RESULTS: Median age was 66 years-old (range, 41-80 years). Four patients were male. Five patients were compulsive drinkers. All patients had no HBsAg and anti-HCV. Initial radiologic diagnoses revealed primary hepatic angiosarcoma (n=2), hepatocellular carcinoma (n=2), hemangioma (n=2), and hepatic metastatic carcinoma (n=2). Definitive diagnoses were made by percutaneous needle biopsies in seven patients and surgical resection in one patient. At the time of the initial diagnosis, extrahepatic metastases were detected in three patients (37.5%). Metastatic sites included the spleen and lung, pericardium, and bone, in one patient each. Two patients underwent conservative treatments. The remaining patients underwent surgical resection (n=1), transcatheter arterial chemoembolization (n=1), and systemic chemotherapy (n=4). The median survival period was 214 days (range, 21-431 days). CONCLUSIONS: Hepatic angiosarcoma is a highly progressive disease with a poor prognosis. Detailed studies including histological examinations are essential to facilitate early diagnosis of the disease.

Primary Pulmonary Low-Grade Angiosarcoma Characterized by Mismatch between 18F-FDG PET and Dynamic Contrast-Enhanced CT

We report a rare case of primary pulmonary low-grade angiosarcoma on dynamic contrast-enhanced CT and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT imaging. A 38-year-old, asymptomatic woman was hospitalized because of an abnormality on chest radiography. A dynamic contrast-enhanced chest CT showed a 1.2 cm-sized irregular-margined nodule with strong and persistent enhancement in the right lower lobe. The lesion had low metabolic activity on an 18F-FDG PET/CT scan. The patient underwent a wedge resection for the lesion, and pathology revealed a primary pulmonary low-grade angiosarcoma.

Angiosarcoma cardíaco: una neoplasia infrecuente / Cardiac angiosarcoma: an infrequent neoplasia

Los tumores cardíacos son infrecuentes, siendo los más comunes los metastásicos. De los primarios, sólo el 25 por ciento son malignos, donde el angiosarcoma es el más frecuente. Este corresponde a un tumor de alto grado de malignidad, caracterizado por un rápido crecimiento, obstrucción de válvulas y metástasis principalmente pulmonares. Es más frecuente entre los 30 y 50años, especialmente en el género masculino, con una relación de2:1. Su clínica es de naturaleza cardiovascular inespecífica y su pronóstico es malo, con una supervivencia de entre nueve a doce meses a partir del diagnóstico. Presentación del caso: Paciente de género femenino, de 50 años de edad, con antecedentes de hipertensión arterial y artritis reumatoide. Consultó por disnea y deterioro de capacidad funcional. Ecocardiograma transtorácico mostró masa de seis centímetros de diámetro, que ocupa toda la aurícula derecha y que generaba obstrucción al flujo tricuspídeo, asociado a derrame pericárdico masivo con taponamiento cardíaco. Tomografía computada (TC) de cerebro, tórax, abdomen y pelvis descartan lesiones metastásicas. Se decidió conducta quirúrgica. Se resecó el tumor y el 70 por ciento de la pared libre de la aurícula y se instaló prótesis valvular biológica; con pericardio autólogo se reconstruyó la aurícula derecha. Evolucionó favorablemente, sin incidentes. Estudio histopatológico concluyó angiosarcoma cardíaco. Discusión: Los tumores cardíacos son infrecuentes. Se deben sospechar en pacientes con clínica cardiovascular, asociada a masa intracavitaria, derrame pericárdicono explicable por otra causa, así como la presencia de metástasis torácicas de un tumor primario desconocido...

Introduction: Cardiac tumors are rare; of them, the metastatic tumors are the most frequent. Of the primary tumors, only 25 percent are malignant, being the angiosarcoma the most common. It is a tumor of high malignancy, characterized by rapid growth, obstruction of cardiac valves and lung metastases. It is most common between 30 and 50 years, especially in men, with a ratio of 2:1. Its symptoms are nonspecific cardiovascular and its prognosis is poor, with a survival of nine to twelve months from diagnosis. Case report: A 50 years old woman with a history of hypertension and rheumatoid arthritis. She presented with dyspnea and impaired functional capacity. Transthoracic echocardiogram showed a mass of 6 cm in diameter, occupying the entire right atrium with tricuspid flow obstruction, associated with massive pericardial effusion with cardiac tamponade. Computed tomography (CT) of the brain, thorax, abdomen and pelvis discarded metastatic lesions. Surgical treatment was decided. The tumor and 70 percent of the free wall of the atrium were resected and biological prosthetic valve was installed, and the righ tatrium was reconstructed with autologous pericardium. She evolved favorably, without incident. Histopathological reports confirmed cardiac angiosarcoma. Discussion: Cardiac tumors are rare. They should be suspected in patients with cardiovascular symptoms, associated with intracavitary mass, pericardial effusion not explained by other causes, as well as the presence of thoracic metastases from an unknown primary tumor...

Intra-cardiac angiosarcoma.

Intra-cardiac angiosarcoma is a challenging disease – difficult to diagnose early and an aggressive tumour to treat. Transoesophageal echocardiography (TEE) and cardiac computed tomography are the two most sensitive diagnostic tools. Though there are various multimodality treatment options available, the results are not impressive. We present a case of intra-cardiac angiosarcoma in a 62-year-old gentleman.

Angiosarcoma primario de mama y carcinoma papilar de tiroides sincrónico: presentación de un caso / Primary breast angiosarcoma and synchronous papillary carcinoma of thyroid: a case report

Presentamos el caso excepcional de paciente con angiosarcoma primario de mama y carcinoma papilar de tiroides sincrónicos. Mujer de 34 años con angiosarcoma primario en la mama derecha sometida a mastectomía simple. En el estudio de extensión se halló un incidentaloma tiroideo derecho compatible con carcinoma papilar que requirió tiroidectomía total y linfadenectomía del compartimento central en segundo tiempo. Los angiosarcomas primarios suponen menos del 0,05% de todos los tumores primarios malignos de la mama. El diagnóstico definitivo de estos tumores viene definido por el estudio anatomopatológico, que define tres grados: alto, bajo, intermedio, los cuales se relacionan de forma directa con la supervivencia. La prevalencia de los incidentalomas malignos tiroideos objetivados por PET varía del 14% - 30,9%. La planificación del tratamiento quirúrgico de las neoplasias incidentales tiroideas en pacientes con otro tumor primario debe analizarse de forma individualizada, según la supervivencia esperada del tumor primario

Present the exceptional case of a female patient with diagnostic of primary angiosarcoma of the breast and synchronous thyroid papillary carcinoma, we review the literature. Patient female 34 year old with diagnostic of primary angiosarcoma in the right breast, it was removed,in the extension study found an incidental thyroid papillary carcinoma that required total thyroidectomy and central lymphadenectomy in a second time. The primary angiosarcomas account for less than 0.05% of all primary malignant tumors of the breast. The definitive diagnosis is determined by the pathology study, which defines three grades: high, low and intermediate, which relate directlyto the survival. The prevalence of malignant thyroid incidentalomas was observed by PET varies from 14% to30,9%, according to different studies. Planning the surgical treatment of incidental thyroid malignancies in patients with other primary tumor should be analyzed individually,according the expected survival of the primary tumor

A nodular growth on maxillary gingiva.

A case of angiosarcoma of maxilla is presented. The occurrence of angiosarcoma in the oral cavity is a rare incidence and maxilla is one of the rarest sites to be involved. The purpose of this article is also to emphasize the fact that sometimes small, innocent-looking masses in the oral cavity might actually turn out to be a highly destructive malignant tumor. Hence, a complete radiographic and histopathologic examination is mandatory.

Palliative bypass for a large advanced angiosarcoma of right atrium and right ventricle with pericardial effusion: case presentation

We present the case of an advanced and large cardiac angiosarcoma in the right atrium and right ventricle, which occupied the most part of the right heart and created a significant stenosis in the pulmonary circulation. Our patient was in very bad general condition with severe respiratory distress and had very unstable hemodynaic. Also, he experienced two episodes of CPR [cardiopulmonary resuscitation] before he was transferred to the operating room. Given the patient's poor condition and limited life expectancy, we performed a palliative bypass procedure, consisting of cavopulmonary anastomosis
