Hemangiomas are vascular tumors, distinct from malformations. This review clarifies hemangioma types and recommends abandoning the imprecise term "segmental hemangioma" for accurate vascular lesion description.

Area of Science:

  • Vascular Surgery
  • Dermatology
  • Pediatric Medicine

Background:

  • Hemangiomas are common vascular tumors in infants and children.
  • The terminology surrounding hemangiomas is often confused with vascular malformations.
  • Misapplication of the term 'hemangioma' by specialists can lead to diagnostic and treatment challenges.

Purpose of the Study:

  • To clarify the distinction between hemangiomas and vascular malformations.
  • To review the primary classifications of hemangiomas, including infantile, rapidly involuting, and noninvoluting types.
  • To address complex hemangioma presentations and propose standardized terminology.

Main Methods:

  • Literature review of hemangioma classifications and terminology.
  • Analysis of common misnomers in vascular lesion description.

Related Experiment Videos

  • Discussion of clinical implications of accurate terminology.

    • Main Results:

    • Hemangiomas are distinct from vascular malformations.
    • Key hemangioma types include infantile, rapidly involuting, and noninvoluting.
    • Complex cases like hepatic hemangiomas and PHACES syndrome are discussed.
    • Proposed terminology includes solitary (small, large, diffuse) and multifocal descriptions.

    Conclusions:

    • The term 'hemangioma' is frequently misapplied.
    • Accurate classification and descriptive terminology are crucial for patient care.
    • The term 'segmental hemangioma' is considered imprecise and should be discontinued.
