This case report highlights cutaneous angiosarcoma (CA), a rare cancer, that can mimic inflammatory conditions. Early diagnosis is crucial as this aggressive cancer can spread rapidly, leading to poor patient outcomes.

Area of Science:

  • Oncology
  • Dermatopathology
  • Medical Case Reports

Background:

  • Cutaneous angiosarcoma (CA) is a rare malignancy of vascular endothelium.
  • Poorly differentiated CA can present diagnostic challenges, sometimes mimicking inflammatory skin conditions.

Observation:

  • A patient presented with a poorly differentiated facial cutaneous angiosarcoma (CA).
  • The tumor exhibited positive staining for CD-34, CD-31, and vimentin, but negative for Factor VIII and Ulex europeaus lectin.
  • The patient had a superinfection with Pseudomonas aeruginosa.

Findings:

  • The angiosarcoma demonstrated rapid local invasion and early metastasis.
  • Histopathological diagnosis was delayed due to initial presentation mimicking an inflammatory process.
  • The patient succumbed to the disease within six months, with autopsy revealing widespread lung and liver metastases.

Implications:

  • This case underscores the importance of considering rare malignancies like CA in the differential diagnosis of facial lesions, especially when they present with atypical features.
  • Delayed diagnosis of cutaneous angiosarcoma can lead to aggressive disease progression and reduced survival rates.
  • Awareness of CA's potential to masquerade as inflammation is critical for timely and accurate diagnosis in clinical practice.
