A preretinal mass mimicking an intraocular metallic foreign body was identified. Histology revealed it was composed of blood breakdown products within a fibrous capsule.

Area of Science:

  • Ophthalmology
  • Ophthalmic Pathology

Background:

  • Preretinal masses can present diagnostic challenges.
  • Metallic foreign bodies are a common cause of intraocular injury.

Observation:

  • A 30-year-old man presented with unilateral iridocyclitis.
  • An ipsilateral preretinal mass was noted with imaging characteristics suggestive of a metallic foreign body.

Findings:

  • Histologic examination revealed a central concentration of iron-containing hemoglobin breakdown products.
  • The mass was surrounded by a fibrous capsule, simulating a foreign body.

Implications:

  • This case highlights that blood breakdown products can mimic metallic foreign bodies on imaging.
  • Accurate diagnosis is crucial for appropriate management of preretinal masses.
