Primary renal epithelioid angiosarcoma (EAS) is extremely rare and carries a poor prognosis. Herein, we present a case of renal EAS in an 81-year-old male patient who complained of hematuria for 1 year. A computerized tomography (CT) scan revealed an occupying lesion at the upper pole of the left kidney, with scattered calcifications, along with retroperitoneal lymph node metastasis and possible lung metastasis.

Article Synopsis
  • Primary pleural angiosarcoma (PPA) is a rare and difficult-to-diagnose tumor often confused with other cancers like mesothelioma and lung cancer due to similar symptoms and imaging results.
  • A 52-year-old woman experienced severe shortness of breath and chest pain, with imaging revealing a large bleeding pleural effusion and medical thoracoscopy identifying abnormal pleura with nodular lesions.
  • Diagnosis was confirmed through histopathology with specific tumor markers, but unfortunately, the patient developed an infection and died before receiving treatment, highlighting the challenges in diagnosing PPA.

Mediastinal angiosarcoma mimicking constrictive pericarditis and aortic dissection: a case report.

Gen Thorac Cardiovasc Surg Cases

February 2024

Department of Cardiovascular Surgery, Kyoto Prefectural University of Medicine, 465 Kajii-cho, Kawaramachi-Hirokoji, Kamigyo-ku, Kyoto, 602-8566, Japan.

Article Synopsis
  • * A case involving a 49-year-old man revealed that initial diagnoses suggested other conditions like constrictive pericarditis, but surgery ultimately confirmed the presence of a malignant tumor after only a pericardiectomy was performed.
  • * The study highlights that mediastinal angiosarcoma can present with diverse symptoms resembling other diseases, and suggests that high hyaluronic acid concentration in pleural fluid could be a potential diagnostic marker.

There is an emerging group of distinct vascular neoplasms with NFATC1/2 fusions, involving bones and soft tissues and often displaying focal epithelioid morphology, variable atypia of endothelial cells, predominantly vasoformative and in some cases focal solid growth. Although they may show aggressive local growth and may recur locally, malignant behaviour has not been documented. We present a case of a 35-year-old woman with multiple vascular neoplasms with a EWSR1::NFATC2 fusion involving the lungs, multiple bones (vertebra, femurs, tibia, pelvis) and probably the liver.
