Recurrent Conjunctival Myofibrosarcoma Managed With Triple Application of Episcleral Brachytherapy.
OBJECTIVE
To report a case of recurrent conjunctival myofibrosarcoma treated with wide surgical excision, cryotherapy, and triple sequential applications of episcleral brachytherapy.


METHODS
A single case of recurrent conjunctival myofibrosarcoma.


RESULTS
A 54-year-old man with a history of a renal transplant presented with a recurrent conjunctival tumor. Histopathologic diagnosis was established through immunohistochemistry. In total, 3 iodine radiation episcleral plaques were used over a period of 49 weeks. After cicatricial ectropion repair and cataract surgery, visual acuity was 20/20 at 4.5-year follow-up without evidence of recurrence or radiation retinopathy.


CONCLUSIONS
Myofibrosarcoma is a rare mesenchymal tumor that can present as ocular surface tumor. Final histopathologic diagnosis can be challenging, and immunohistochemistry is important for evaluation. Myofibrosarcoma should be considered in the clinical differential diagnosis of atypical ocular surface lesions and the histopathologic differential diagnosis of ocular spindle neoplasms.
