Case Study: January 2010
A 30 year old presents with a white mass over the cornea.
At surgery, the lesion was located between the corneal epithelium and Bowman’s and the surgeon peeled it off without difficulty.
Figure 1 and Figure 2 show the lesion.
Figure 3 is an anti-smooth muscle actin immuno.
Figure 4 is an Alcian Blue stain.
Questions
1. What are the features of this lesion?
2. What is the differential diagnosis?
3. What is the most likeliest diagnosis?
- Spindle cell myxoid lesion covered by epthelium
- Myxoid degeneration, primary corneal myxoma, Salzmann’s nodule (early cellular phase), nodular scarring, neurofibroma
- The patient had no history of corneal disease. The favoured differential is primary corneal myxoma
