Area of Science:

  • Dermatology
  • Pathology
  • Oncology

Background:

  • Microvenular hemangioma is a rare benign vascular tumor.
  • Distinguishing it from malignant vascular neoplasms is crucial for appropriate patient management.

Observation:

  • A 23-year-old Japanese female presented with a solitary, slowly growing reddish plaque on her back.
  • Histopathological examination revealed an infiltrative dermal tumor composed of small, thin-walled, irregularly branched vascular channels with narrow lumina.

Findings:

  • Endothelial cells lining the vessels were positive for endothelial markers and lacked atypia or mitotic activity.
  • The tumor demonstrated infiltrative growth throughout the dermis.

Implications:

Related Experiment Videos

  • This case highlights the importance of recognizing microvenular hemangioma's infiltrative pattern.
  • Pathologists and clinicians should be aware of this entity to avoid overdiagnosis and overtreatment of benign vascular lesions.
