Area of Science:

  • Dermatology
  • Pathology

Background:

  • Multinucleate cell angiohistiocytoma (MCAH) is an uncommon dermatological condition.
  • MCAH typically presents as papules or nodules on the skin.

Observation:

  • A case of MCAH presented clinically as a large, indurated cutaneous plaque measuring 12 x 6 cm on the trunk.
  • The patient was a 74-year-old woman.

Findings:

  • Histopathologic examination confirmed the diagnosis of MCAH.
  • This represents the first reported instance of MCAH manifesting as a plaque.

Implications:

  • MCAH can present with a broader range of clinical morphologies than previously recognized.
  • Clinicians should consider MCAH in the differential diagnosis of solitary cutaneous plaques.
