Atypical Fibroxanthoma/Pleomorphic Dermal Sarcoma With Osseous Metaplasia: A Series of Three Cases

Journal of Cutaneous Pathology, Volume 53, Issue 5, Page 407-413, May 2026.
ABSTRACT Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) are rare mesenchymal tumors typically arising on sun‐damaged skin of the head and neck in elderly patients. PDS is a more aggressive tumor but with similar demographics, cellular morphology, immunohistochemical features, and genetic findings.

Hepatic angiosarcoma with metastasis to small intestine [PDF]

, 2008
Hepatic angiosarcomas are rare tumours with poor prognosis, with patients usually dying within 6 months. Metastases mainly occur in lymph nodes, spleen, lungs, bones and adrenals. Metastasis to small intestine is even rarer.

Cardiac Angiosarcoma

Case Reports in Cardiology, 2011
Despite cardiac metastases are found in about 20% of cancer deaths, the presence of primary cardiac tumors is rare. Most primary tumors are benign, and malignant tumors comprise about 15%. We report a 21-year-old man with fever, dyspnea, and hemoptysis that was diagnosed with angiosarcoma of the right atrium and pulmonary metastasis.

CT Features of an Extraskeletal Osteosarcoma Associated With a Retained Surgical Sponge in a Dog

Veterinary Radiology &Ultrasound, Volume 67, Issue 3, May 2026.
ABSTRACT An 8‐year‐old neutered female Labradoodle presented with acute restlessness and inability to stand. Point‐of‐care ultrasound revealed a large abdominal mass, prompting further imaging. Computed tomography (CT) demonstrated a mass with marked mineralization, a thick, enhancing rim, and signs of intra‐abdominal dissemination.

Angiosarcoma of the auricle

European Annals of Otorhinolaryngology, Head and Neck Diseases, 2016
Angiosarcomas are rare but aggressive vascular cancers of endothelial cell origin. The diagnosis is often difficult, based on specific immunohistological features. They characteristically present a high local recurrence rate and an early metastatic potential.We report a case of angiosarcoma of the auricle in a 31-year-old female patient who presented ...

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

FEBS Open Bio, Volume 16, Issue 4, Page 803-813, April 2026.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Angiosarcoma of the breast, the unknown—a review of the current literature

Translational Cancer Research, 2019
Angiosarcoma of the breast is one of the rarest malignancies. Breast angiosarcoma can be classified into primary when arising de novo and secondary to chronic lymphoedema or breast irradiation. Molecular pathways involved in angiosarcoma development have
