Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria: The participant must have a clinically confirmed superficial/ cutaneous (visible on the skin) venous malformation (cVM), referred to as the treatment area. The treatment area may contain a minority (<30%) lymphatic component (mixed venous / lymphatic malformation).

-

Exclusion Criteria:

  • The participant's treatment area is mainly in any wet mucosa or within the orbital rim. For clarification, no part of the venous malformation should be evaluated or treated if it in mucosa. External genital presentation is permitted.
  • The participant has a known pervasive extension of the lesion into mucosa, bone or tissue (as determined by diagnostic or the investigator) that would impair the ability of the investigator to evaluate the cutaneous components of the lesion.
