Purpose: To report a case of recurrent myxomatous corneal degeneration after pterygectomy.
Case summary: A 65-year-old man with a history of abdominal keloid was referred to our hospital for assessment of a well-circumscribed, gelatinous, whitish corneal mass on the nasal corneal area of the left eye that appeared one month prior. The patient had undergone pterygectomy on his left eye 2 years ago. The patient experienced mild foreign body sensation. The other anterior segment and fundus examination of the left eye were both normal. We diagnosed the case as keloid and we performed excisional biopsy of the corneal mass. Histologic findings revealed proliferation of myxoid-appearing material in the anterior corneal stroma. On immunohistochemical examination, sections were stained positive for actin and calretinin, and negative for S-100. We diagnosed the tumor as myxomatous corneal degeneration. After six months, a recurrent mass was found on the previously excised site. Re-excisional biopsy and topical interferon α-2b treatment were then performed in response. After re-excision, there was no recurrence or complications during one year follow-up.
Conclusions: Myxomatous corneal degeneration should be considered during differential diagnosis of an elevated, whitish, gelatinous lesion of the cornea with previous history of trauma or operation, such as pterygectomy. An interferon α-2b topical treatment is useful for recurrent corneal myomatous degeneration.
