1*California Pacific Medical Center, San Francisco, California; †Department of Ophthalmology, Stanford Medical Center, Stanford, California; ‡Department of Ophthalmology, University of California San Francisco Medical Center, San Francisco California; and §The Tumori Foundation, San Francisco, California.
Purpose:
Establishing the correct diagnosis of a growing choroidal tumor can be difficult.
Methods:
Clinical examination and ultrasound of a patient followed for what was thought to be a uveal melanoma. Fine-needle biopsy established the correct diagnosis.
Results:
We demonstrate that fine-needle biopsy can correctly identify a very rare tumor, a myomelanocytic neoplasm.
Conclusion:
Myomelanocytic choroidal tumors can be diagnosed on fine-needle biopsy.
