Primary renal angiosarcoma: A case report and a short review of literature

Angiosarcoma of breast and chest wall complicated with tuberculous empyema: A case report

Angiosarcoma is a highly malignant endothelial tumor, accounting for 1% to 2% of soft tissue sarcomas. The most common site of the disease is the skin, accounting for approximately 60% of cases, especially the skin of the head. It can also occur in soft tissue, bone, and retroperitoneum. However, angiosarcomas of the breast and chest wall are rare. Here, we report a 44‐year‐old woman who was admitted to hospital with encapsulated empyema. She was subsequently diagnosed with angiosarcomas of the breast and chest wall with tuberculous empyema. At the same time, we also reviewed the current research progress in angiosarcoma of the breast and chest wall to explore better treatment options for these patients.

Primary vascular tumours of the kidney

Primary vascular tumours of the kidney are rare and may pose diagnostic difficulties because of their similar clinical, morphological, and immunohistochemical features. This article summarizes the clinical and pathological features of primary renal angiosarcoma and anastomosing haemangioma of the kidney including epidemiology, genetics, and prognosis. Renal anastomosing haemangiomas are benign neoplasms characterized by anastomosing capillary-sized vascular channels. These tumours are rare, with about 75 cases reported in the literature. Most anastomosing haemangiomas are found incidentally on ultrasound, computed tomography, or magnetic resonance imaging. Common symptoms include abdominal pain, haematuria, and abdominal mass. Renal anastomosing haemangiomas are characterized by recurrent mutations in GNAQ and GNA14 genes. The prognosis of anastomosing haemangioma is excellent. Primary renal angiosarcomas are malignant tumours showing endothelial differentiation. To date, 76 cases have been described in the literature. Primary renal angiosarcomas are frequently symptomatic. The clinical features of renal angiosarcomas are similar to those of renal anastomosing haemangiomas, including abdominal pain, haematuria, and abdominal mass. Angiogenesis-related genes and vascular-specific receptor tyrosine kinases such as KDR, TIE1, SNRK, TEK, and FLT1 are upregulated in angiosarcomas. Primary renal angiosarcomas are highly aggressive neoplasms with a poor prognosis despite surgical treatment, chemotherapy, radiotherapy, or targeted therapy.

Primary renal angiosarcoma mimicking urothelial carcinoma - A case report and literature reviews

Angiosarcoma (AS) is a rare aggressive tumor originating from endothelial cells. We reported a 66-year-old female with primary renal angiosarcoma (PRA) who presented as urothelial carcinoma with hematuria and dysuria. Based on ureterorenoscopic tumor biopsy, the initial diagnosis suggested low-grade non-invasive urothelial carcinoma. However, the specimen retrieved from nephroureterectomy confirmed the diagnosis of primary renal angiosarcoma.

Primary renal angiosarcoma could uncommonly present as urothelial carcinoma in renal pelvis. Surgical resection remains to be the most effective therapy but there is no consensus about adjuvant therapies. The overall prognosis of primary renal angiosarcoma is dismal.

•

Primary renal angiosarcoma is a rare disease that could mimic urothelial carcinoma.

•

Surgical resection is considered to be main treatment.

The effectiveness osf adjuvant therapies remain to be clarified.
