Conjunctival Nevus

AbstractPurpose of ReviewTo provide an up-to-date review of the epidemiology, presentation, diagnosis, and treatment options for conjunctival nevi (CN).Recent FindingsAround 17.2%-42% of all conjunctival tumors have been found to be CN, which most frequently present in White individuals between the first to early third decade of life, with equal distribution between males and females. CN commonly occur in the interpalpebral bulbar conjunctiva with pigmentation ranging from amelanotic to dark. Diagnosis is typically made through slit lamp examination, visualized by a well circumscribed, variably elevated, variably pigmented, solitary lesion with clear cysts distributed throughout the pigment. In ambiguous cases, anterior segment optical coherence tomography (AS-OCT) can highlight the presence of sub-clinical cysts, whose presence points to a diagnosis of nevus. However, excisional biopsy with histopathology examination is the gold standard for identifying CN.SummaryCN are benign, variably pigmented lesions. They are the most common of the conjunctival melanocytic tumors. Due to the extremely low risk of transformation to malignant melanoma (MM), CN are usually managed with routine observation and photo documentation.
