Delayed foreign-body reactions, known as pencil-core granulomas, can mimic melanoma. Surgeons should remove all pencil fragments to prevent these granulomas.

Area of Science:

  • Dermatology
  • Pathology
  • Surgical Complications

Background:

  • Pencils are sometimes used by surgeons for marking surgical sites.
  • Retained foreign material in surgical wounds can elicit inflammatory responses.

Observation:

  • Noncaseating granulomas can develop as a delayed reaction to graphite from pencil cores.
  • These granulomas can clinically resemble malignant melanoma.

Findings:

  • The presence of noncaseating granulomas is a foreign-body reaction to retained pencil fragments.
  • The clinical presentation of these granulomas can be mistaken for melanoma, a type of skin cancer.

Implications:

  • Surgeons using pencils for marking should be aware of the risk of late-onset pencil-core granulomas.

  • Minimizing the risk involves meticulous removal of all pencil lead fragments from surgical wounds.
  • Early recognition and differentiation from melanoma are crucial for appropriate patient management.
