Foreign material is something that is extrinsic to the body.

Foreign body redirect to this article.

Fecal material is dealt with separately in the article fecal material. Sutures are dealt with separately in the article suture material.

General

  • Relatively common.
  • Seen in a number of contexts.
    • Pica - ingestion of nonfood items.[1]
    • Trauma.
    • Embolization procedures, may use gelatin sponge.[2]
    • Previous surgery - suture material, degradable surgical sponges.[3]

Gross

  • Looks like it doesn't belong, e.g. food.
  • Obvious foreign bodies are gross only diagnoses.
    • Examples:
      • A dildo removed surgically from a body orifice.
      • A bullet removed in surgery - should be handled with care, photographed... probably will become evidence.

Microscopic

Features:

  • Material with out nuclei.
  • May be honeycomb-like, cartilage-like or muscle-like.
  • May have a glassy appearance - see oxidized cellulose‎.
  • Often homogenous or patterned.
