The MarginMarker histology marking dyes provide greater certainty that the designated margin for re-excision is correct.
The MarginMarker histology marking dyes provide greater certainty that the designated margin for re-excision is correct.   Surgeons use the MarginMarker tissue ink kit to mark margins of excised tissue while in the operating room. Our tissue margin marking dyes completely define each margin plane, so that the pathology lab receives a clearly marked specimen.

The New Standard for Tissue Orientation®

In the quest to provide the best possible care for cancer patients, leading hospitals and physicians are eliminating error and improving patient outcomes by using Vector Surgical's MarginMarker. Surgeons use the MarginMarker sterile ink kit to define margins of excised tissue while in the OR; the pathology lab receives a clearly marked specimen. Unlike suture or metal tags, MarginMarker inks completely define each margin plane, resulting in more accurate re-excisions and potentially lower cancer recurrence.


MarginMarker sterile inks fully define each margin surface, providing more secure and accurate designation of tissue margins. Use of MarginMarker can result in:

Better Patient Outcomes

  • Fewer unnecessary re-excisions 1, 2
  • More accurate re-excisions 1, 2, 3
  • Potentially lower cancer recurrence when complete resection is accomplished 4, 5, 6
  • Better cosmesis due to re-excision of less tissue 4

Valuable Time Saved

  • More efficient surgeon-pathologist communication

Improved Safety

  • Less risk of needle stick in the OR

MarginMarker Sterile Ink Kit

  • The MarginMarker sterile ink kit is a sterile, single use device. The kit includes six ink colors, applicators, fixative, and annotation labels.


Performance of MarginMarker Inks

  • Formulated to secure to tissue, allowing precise and quick application in the OR
  • Adhere throughout specimen processing, including after suspension in formalin
  • Sterility supports cytogenetic analysis or microbiology testing
  • Minimize the risk of cross contamination with multiple specimens



Cancer surgeries in which tissue orientation is important, including:

  • General and Oncological Surgeons: Breast, pancreas, colon, liver, lip, anus, ovary, uterus, labia and soft tissue
  • Plastic, ENT and Dermatological Surgeons: Basal skin cancer, squamous cell carcinoma and melanoma
