A hemorrhagic lesion initially diagnosed as age-related macular degeneration (AMD) was surgically removed. Histopathology revealed it was actually a choroidal melanoma, highlighting the need for tissue examination.

Area of Science:

  • Ophthalmology
  • Surgical Pathology

Background:

  • A hemorrhagic lesion in the macula of a 77-year-old male was evaluated.
  • Initial diagnosis suggested subretinal neovascular membrane secondary to age-related macular degeneration (AMD).

Observation:

  • The lesion was surgically excised.
  • Histopathologic and immunohistochemical analyses were performed on the excised tissue.

Findings:

  • The excised lesion was identified as a small, epithelioid cell choroidal melanoma.
  • This diagnosis differed from the initial clinical assessment of AMD.

Implications:

  • Unusual macular hemorrhagic lesions require careful histopathologic examination.
  • Modern surgical approaches for AMD may necessitate tissue analysis to avoid misdiagnosis of conditions like choroidal melanoma.
