Solitary adult orbital myofibroma: Report of a case and review of the literature

Intraosseous solitary myofibroma of the orbit in an adolescent woman

A 16-year-old woman presented with a painless, progressive, hard swelling in the left inferolateral orbital wall for the past 1 year. There was no diminution of vision or limitation of ocular motility. Imaging revealed an intraosseous, well-defined, expansile, soft tissue lesion in the inferolateral wall of the left orbit. A left anterior orbitotomy with complete surgical excision was performed. Histopathological evaluation of the specimen revealed fascicular pattern of spindle cells with a rich network of slit-like, branching blood vessels. Tumour cells exhibited smooth muscle actin and vimentin positivity but were negative for CD-34 and STAT-6. In absence of any systemic manifestation, a diagnosis of intraosseous solitary orbital myofibroma was made. The case highlights the importance of integrating clinical, radiological and histopathological features in overcoming the diagnostic challenge of differentiating myofibroma from other mesenchymal neoplasms. It also brings forth the importance of complete resection and curettage to prevent recurrence.

Epibulbar solitary myofibroma in an elderly patient: a case report

A 93-year-old male patient presented with abrupt expansion of an old epibulbar mass at the temporal area of the left eye. He had a medical history of previously treated laryngeal cancer with surgery and radiotherapy. The tumor, despite being firmly attached to the underlying sclera, was excised completely and histopathological examinations revealed a solitary myofibroma. The patient had a 4-month uneventful follow-up with excellent wound healing. Solitary myofibroma may be a differential diagnosis for epibulbar masses in elderly patients.
