Summary

Intravascular papillary endothelial hyperplasia (IPEH), or Masson's tumor, is a benign skin lesion. This report details the first case of Masson's tumor in the medial canthal region, mimicking dacryocystitis.

Area of Science:

  • Dermatology
  • Ophthalmology
  • Pathology

Background:

  • Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's tumor, is a benign vascular lesion.
  • IPEH is a reactive, non-neoplastic proliferation of vascular endothelial cells, often linked to vascular insult like thrombosis.
  • It typically affects the head, neck, and arms, predominantly in females, and accounts for approximately 2% of cutaneous vascular tumors.

Observation:

  • This case presents the first documented instance of Masson's tumor occurring in the right medial canthal subcutaneous tissue.
  • The lesion initially presented as a condition mimicking dacryocystitis, a common eye infection.

Findings:

  • The diagnosis of IPEH was confirmed in the medial canthal region.
  • This presentation highlights the potential for IPEH to masquerade as other orbital and adnexal conditions.

Implications:

  • This case expands the known anatomical distribution of Masson's tumor.
  • Awareness of this presentation is crucial for accurate diagnosis and appropriate management of medial canthal masses.
  • Further investigation into the reactive mechanisms of IPEH in this unique location may be warranted.
