Topical erythropoietin has been recently introduced for the treatment of avascular conjunctival and scleral lesions. Before this treatment can be routinely used, however, its safety profile and contraindications should be determined. Herein, we report a case of recurrent conjunctival squamous cell carcinoma (SCC) and intraocular tumor extension after treatment with topical erythropoietin for excisional biopsy-induced scleral necrosis. An 87-year-old man underwent excisional biopsy for a conjunctival leukoplakic mass. Histological examination showed a well-differentiated SCC on the postoperative day 10. All borders of the specimen were reported to be involved with tumoral cells. The patient did not receive further surgical intervention or topical mitomycin since he developed surgically induced scleral necrosis on the postoperative day 14. Topical erythropoietin 3,000 IU/mL was started every 6 h, and avascular scleral lesion healed over 21 days of treatment with topical erythropoietin. However, 4 months after complete improvement, the tumor recurred with extension into the anterior chamber. Ultrasound biomicroscopy showed the involvement of sclera, iris root, and ciliary body with blunting of the anterior chamber angle. Orbital extension was not detected in magnetic resonance imaging. Topical erythropoietin administered in eyes with a history of conjunctival SCC could be linked to tumor recurrence and intraocular invasion. We recommend avoiding topical erythropoietin in eyes with existing conjunctival SCC or a previous history of conjunctival SCC that was incompletely removed. |
