Mesectodermal Leiomyoma of Ciliary body in a young female

We report a rare case of a young lady of 22 years who presented with minor decrease of vision in her left eye since two weeks and on examination showed a large brown mass lesion just behind the lens. Based on the clinical features, trans illumination, ultrasonography and magnetic resonance imaging of the orbit, a potential diagnosis of ciliochoroidal melanoma was made. After proper counselling and explanation to the patient and parents keeping in consideration the size of the lesion, the eye was enucleated. Histopathological examination confirmed it to be a mesectodermal leiomyoma of the ciliary body. Such benign lesions can rarely attain large sizes with clinical features simulating tumours like melanoma, thus making management, challenging for the physician.
