Here, we report a case of pyothorax ‐associated angiosarcoma. Our patient had computed tomography (CT) scans of the chest annually to monitor chronic empyema, and to screen for cancers. Our patient was diagnosed with angiosarcoma within a month period after complaining of chest pain. This is the very first report on angiosarcoma who se aggressive growth could be observed on CT imaging. An 82 ‐year‐old man with chronic tuberculous empyema visited our hospital for an annual computed tomography (CT) scan. No differences were noted between the CT scan at presentation and a scan performed a year previously in August 2017….

AbstractBackgroundPrimary cardiac angiosarcoma (PCAS) is a rare type of tumour. Furthermore, descriptions of the demographic features and prognostic factors of PCAS patients have been poorly reported.MethodsA population cohort study was conducted using retrospectively extracted data from the SEER (Surveillance, Epidemiology and End Results) database for patients with histological diagnoses of PCAS; the extracted information included demographic, treatment and outcome data.ResultsA total of 168 cases of PCAS from 1973 to 2013 were included. The mean age at diagnosis was 44.4  ± 15.5 years. PCAS was…

ConclusionsThis case series underscores the value of targeted immunotherapy in treating angiosarcoma. It also identifies genetic heterogeneity of cutaneous angiosarcomas and discusses specific genetic findings that may explain reported benefits from immunotherapy.

AbstractFibrous dysplasia (FD) is generally considered to be a benign disease that affects the bones, but it has potential to become malignant over time, generally several decades after its initial diagnosis. Radiation therapy can induce malignant transformation of FD; however, reports have indicated a few cases of malignant transformation of FD in the absence of radiation therapy. Angiosarcoma is a particularly rare type of cancer in the oral region, which accounts for less than 1% of all soft-tissue sarcomas. Herein, we reported a case of a 62-year-old man with monostotic FD of the left maxilla of over 50  years&rsq…

A 72-year-old woman presented with 2-month history of “bruises” on the left breast. She was treated for a left breast cancer 6 years earlier. She previously had stage IA (cT1cN0M0) invasive ductal carcinoma that was estrogen receptor/progesterone receptor positive and Her2 negative. She underwent partial mastectomy and sentinel lymph node biopsy th at confirmed stage pT1cN0. In the setting of bilateral silicone breast implants, she received adjuvant partial breast irradiation to 36 Gy in 9 fractions twice daily, targeting the seroma with 1.5 to 2 cm margins.

Angiosarcomas are rare but aggressive tumors with poor prognosis. The treatment of angiosarcomas with vascular endothelial growth factor receptor inhibitors is still in the stage of clinical exploration. Herein we reported a patient of skin angiosarcoma with multiple organ metastasis. She was resistance to multiline chemotherapy and pazopanib but achieved remarkable shrinkage of the lesion after apatinib treatment combined with chemotherapy or alone. The progression-free survival of the primary lesion with KRAS V14I and RBM10 E119D mutations (10 months) was shorter than that of the brain without the mutation ( ≥ 12 mont…

This is a short clinical report depicting an exceptionally early presentation of radiation-induced angiosarcoma and overview of the literature. This case highlights the need for a high level of clinical suspicion in those patients presenting with unresolving cutaneous skin changes after radiotherapy for breast cancer.
Breast-conserving therapy, comprising breast-conserving surgery and adjuvant radiotherapy, has largely replaced mastectomy in the treatment of early-stage breast carcinoma. Breast angiosarcoma is a rare but severe long-term complication associated with postoperative radiotherapy (Int J Radiat Oncol Biol Phys…

ABSTRACT
Angiosarcomas are a rare group of tumours which have poor prognosis and limited treatment options. The development of new therapies has been hampered by a lack of good preclinical models. Here, we describe the development of an autochthonous mouse model of angiosarcoma driven by loss of p53 in VE-cadherin-expressing endothelial cells. Using Cdh5-Cre to drive recombination in adult endothelial cells, mice developed angiosarcomas with 100% penetrance upon homozygous deletion of Trp53 with a median lifespan of 325 days. In contrast, expression of the R172H mutant p53 resulted in formation of thymic lymphomas wit…

We describe cutaneous SCC of the plantar foot in two patients exposed to high doses of PLD. A 50-year-old man with angiosarcoma received a total PLD dose of 1350  mg/m2 and developed cutaneous SCC of bilateral plantar feet. A 45-year-old woman with cutaneous T-cell lymphoma was treated with a total PLD dose of 1142  mg/m2 with subsequent diagnosis of cutaneous SCC of the right plantar foot. No risk factors for SCC of the plantar foot were identified in either patient. Cutaneous SCC is likely an unreported side effect of prolonged exposure to PLD. An extended duration of hand –foot syndrome from other anti-c…
