60-year-old woman presented with a 1-day history of bleeding from the right eye; the bleeding began upon awakening and resolved 1 hour after onset. There were no other ocular symptoms. Her past ocular history was notable for bilateral blepharitis and recurrent chalazia in her right eye, which was treated by incision and curettage. She was otherwise healthy, and the rest of her medical history was unremarkable.

Her visual acuity was 20/20 in both eyes. Visual fields, pupils, extraocular movements, intraocu- lar pressure, and fundoscopy results were nor- mal. No lesion was visible upon gross external examination; however, a red, beefy, peduncu- lated nodule protruded from the inferior palpe- bral conjunctiva of the right eye upon manual lower lid retraction.

The most likely diagnosis is 1. Chalazion

2. Squamous cell carcinoma 3. Pyogenic granuloma 4. Malignant melanoma
