Area of Science:

  • Dermatology
  • Histopathology

Background:

  • Multinucleate cell angiohistiocytoma (MCA) is a rare benign skin proliferation with fewer than 100 reported cases.
  • Its etiology and treatment remain under investigation due to its novelty.

Observation:

  • A 41-year-old female presented with asymptomatic violaceous plaques on extensor surfaces and trunk.
  • Histopathology showed increased dermal vascularity and cellularity, including mononuclear histiocytes and multinucleated giant cells.

Findings:

  • The case confirmed a generalized presentation of multinucleate cell angiohistiocytoma.
  • Histological findings align with the characteristic features of MCA.

Implications:

  • This report expands the understanding of MCA's clinical presentation.
  • Further research into the immunology, etiology, and treatment of MCA is warranted.
