She reported no additional symptoms and had no relevant medical, family or ocular history. On examination, a subconjunctival nodule measuring approximately 4\u00d74\u2009mm was noted in the nasal conjunctiva. The lesion was elevated, and no other abnormalities were observed. Extraocular movements were intact. The patient was scheduled for surgical excision. During surgery, the lesion had increased in size to 6\u00d76\u2009mm and was found to infiltrate the superficial sclera and the insertion of the medial rectus muscle. Histopathological analysis confirmed a diagnosis of benign fibrous histiocytoma. We detail the surgical technique employed and provide a review of the literature. To date, only one other case involving the medial rectus has been reported, which occurred in a 17-year-old girl.<\/jats:p>","DOI":"10.1136\/bcr-2024-260520","type":"journal-article","created":{"date-parts":[[2025,4,26]],"date-time":"2025-04-26T09:55:16Z","timestamp":1745661316000},"page":"e260520","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Benign
