Abstract
Introduction:
Glomus tumours are rare benign tumours formed by modified smooth muscle cells arising from the glomus body. Glomus tumours occurring in the iris have not been previously reported.
Case description:
A 32-year-old woman presented with a 9-day history of blurred vision in her right eye. Ultrasound, computed tomography and magnetic resonance imaging confirmed the presence of a mass lesion within the iris. Surgery of the iris was performed and the tumour was removed. Histopathological analysis confirmed a glomus tumour. The patient remains clinically stable 5 months following surgery and has experienced no tumour recurrence.
Conclusion:
The findings from this case suggest that the typical symptoms of a glomus tumour may be absent in some cases, and that imaging examinations can help in understanding the extent of the lesion and the involvement of adjacent structures. Moreover, pathology and immunohistochemistry are crucial to confirm the diagnosis.
