Multinucleate cell angiohistiocytoma (MCA) is a benign vascular tumor typically found on extremities in older women. This case report details its clinical and histopathologic features, distinguishing it from Kaposi sarcoma.

Area of Science:

  • Dermatology
  • Pathology
  • Oncology

Background:

  • Multinucleate cell angiohistiocytoma (MCA) is a rare, benign fibrohistiocytic vascular tumor.
  • MCA predominantly affects acral sites (extremities, head, neck) in elderly women.
  • Clinical and histological differentiation from Kaposi sarcoma is a significant diagnostic challenge.

Observation:

  • This report presents a case of MCA in a 63-year-old woman.
  • Detailed clinical presentation and physical examination findings are described.
  • Histopathological examination reveals characteristic features of MCA.

Findings:

  • The study highlights the key clinical manifestations of MCA.
  • Histologic findings confirm the diagnosis of multinucleate cell angiohistiocytoma.
