Primary renal angiosarcoma is a rare kidney cancer. This case highlights its presentation with hematuria and abdominal mass, emphasizing its inclusion in differential diagnoses for hemorrhagic renal tumors.

Area of Science:

  • Oncology
  • Pathology
  • Radiology

Background:

  • Primary renal angiosarcoma is an exceptionally rare vascular neoplasm.
  • Fewer than 24 cases have been documented in medical literature.

Observation:

  • A patient presented with hematuria, a palpable abdominal mass, left flank pain, and anemia.
  • A 15 cm tumor in the upper left kidney was identified via contrast-enhanced CT, showing central low density suggestive of necrosis or hemorrhage.

Findings:

  • Morphological assessment and immunohistochemical studies confirmed the diagnosis of primary renal angiosarcoma.
  • The tumor exhibited characteristics consistent with a rare, aggressive malignancy.

Implications:

  • Primary renal angiosarcoma should be considered in the differential diagnosis of retroperitoneal hematomas.
