This case study details a rare cutaneous angiosarcoma in a morbidly obese woman, linked to chronic lymphedema in the abdominal panniculus. The aggressive tumor recurred and metastasized, leading to the patient

Area of Science:

  • Oncology
  • Pathology
  • Dermatology

Background:

  • Cutaneous angiosarcoma is a rare malignancy of vascular endothelium.
  • Morbid obesity can lead to chronic lymphedema in dependent panniculus.
  • This case explores the intersection of these conditions.

Observation:

  • A 35-year-old morbidly obese woman presented with a tumor in her lower abdominal panniculus.
  • The tumor exhibited features of chronic lymphedema.
  • Histopathology revealed a high-grade, multicentric angiosarcoma with lymph node metastases.

Findings:

  • The angiosarcoma showed mixed vasoformative and poorly differentiated areas.
  • Immunohistochemistry was positive for Factor VIII and CD31.
  • Despite negative initial margins, the tumor recurred and widely metastasized post-surgery.

Implications:

  • This case highlights a potential association between chronic lymphedema in morbidly obese panniculus and cutaneous angiosarcoma.
  • It underscores the aggressive nature and poor prognosis of this rare cancer.
  • Further research is needed to understand this specific etiology and improve patient outcomes.
