Question

A 5-year-old boy presents with a small nodule on the sclera as shown in the image below. What is the likely diagnosis?

• A. Pterygium
• B. Pinguecula
• C. Dermolipoma
• D. Dermoid

Answer 1

The Correct Option is D

A 5-year-old boy presents with a small nodule on the sclera. To determine the likely diagnosis, we need to analyze the characteristics of common ocular nodules:

• Pterygium: A benign growth that typically begins at the conjunctiva and can extend onto the cornea. It is usually wedge-shaped and related to UV light exposure. Not common in children.
• Pinguecula: A yellowish, elevated nodule on the conjunctiva, often on the side closest to the nose, associated with aging and sun exposure. Rare in young children.
• Dermolipoma: A congenital, benign, fatty tissue located under the conjunctival surface, typically appearing in the superotemporal quadrant. It is often present at birth or early childhood.
• Dermoid: A choristomatous lesion usually found on the surface of the eye. It can appear as a solid, yellowish-white mass on the limbus (border of sclera and cornea), commonly seen in children.

Considering the age of the child and the presentation of a small nodule on the sclera, the most likely diagnosis is Dermoid. Dermoids are common in the pediatric population and their appearance matches the description provided.
