Differential diagnosis of a nodule at the limbus

Inflammatory lesions
- Phlyctenular keratoconjunctivitis (phlycten)
- Nodular episcleritis
- Nodular anterior scleritis
- Retained foreign body or foreign-body granuloma
Allergic condition
- Limbal papillae/gelatinous limbal hypertrophy in vernal keratoconjunctivitis
Degenerative lesions
- Pinguecula
- Early pterygium
Cystic lesions
- Conjunctival inclusion cyst
- Dermoid cyst
Tumours
- Limbal dermoid or lipodermoid
- Conjunctival nevus
- Papilloma
- Ocular surface squamous neoplasia
- Conjunctival melanoma

Clinical clue: A small white-yellow nodule with surrounding localized congestion, especially in a young patient, commonly suggests a phlycten. A pigmented, enlarging, vascularized, or fixed limbal lesion needs urgent ophthalmic assessment to exclude neoplasia.
