A Rare Case of Conjunctival Myxoma Initially Misdiagnosed as a Conjunctival Inclusion Cyst

Bilateral synchronous conjunctival myxoma and review of the literature

PURPOSE

The purpose of this study was to report the clinicopathological features and management of the first case of bilateral synchronous conjunctival myxoma.

METHODS

This study was a case report and literature review.

RESULTS

A 66-year-old Chinese male with past ocular history of uncomplicated bilateral phacoemulsification and intraocular lens (IOLs) 3 years ago prior to presentation presented with bilateral red and swollen conjunctiva for over a year. On examination his corrected distance visual acuity (CDVA) was 25/20 in the right eye 20/20 in the left eye. Slit lamp examination revealed swollen temporal conjunctiva bilaterally which appeared as painless, well-circumscribed, salmon-pink, fleshy patches. The lesion in the right eye was subsequently excised, followed by excision of the lesion in the left eye at 3-week interval. Microscopically, histopathological examination of both excised specimens revealed hypocellular conjunctival mucosa covered by non-dysplastic epithelium, with presence of myxoid degeneration in the subepithelial stroma and immunostaining findings consistent with conjunctival myxoma. At his latest follow-up at 24 months, there were no recurrences of the conjunctival masses and the CDVA was the same as preoperatively.
