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.
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.
- Examples:
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.
DDx:
- Fecal material - if in colon/rectum.
- Necrotic material.
- Tissue processing artifact.
- Xanthogranulomatous lymphadenitis - if in lymph node.

History of metallic object identified by radiology
The imaging findings are noted. No definite foreign material is seen at microscopy; however, the tissue is disrupted, as may result when a hard material is embedded in the tissue. The tissue block was examined and a fragment that had chunked-out at the time of cutting was noted. The chunked-out fragment and tissue block were x-rayed. The chunked-out fragment was highly radiodense (in keeping with a metallic fragment) and approximately 2 mm in maximal dimension.
Block letters
FOREIGN BODY, RIGHT LOWER LOBE, RETRIEVAL: - MORPHOLOGICALLY CONSISTENT WITH A GREEN PEA (GROSS ONLY).
FOREIGN BODY, BRONCHUS INTERMEDIUS, RETRIEVAL: - MUCOUS WITH NEUTROPHILS AND MACROPHAGES. - BENIGN CALCIFICATIONS. - FOREIGN MATERIAL (HONEYCOMB-LIKE AND CARTILAGE-LIKE WITHOUT NUCLEI) -- COMPATIBLE WITH FOOD. - SCANT STRIPPED BRONCHIAL LINING EPITHELIUM WITHOUT APPARENT PATHOLOGY.
SOFT TISSUE, LEFT ARM, EXCISION: - FOREIGN BODY, APPEARANCE COMPATIBLE WITH A PIECE OF WOOD (GROSS ONLY). - FOREIGN BODY-REACTION (ACUTE AND CHRONIC INFLAMMATION WITH ACTIVATED FIBROBLASTS, HISTIOCYTES AND RARE GIANT CELLS). - NEGATIVE FOR MALIGNANCY.
