Conjunctival nevi are benign tumors, most often located at the nasal or temporal limbus, and rarely in the fornix or tarsus. The vast majority of caruncular tumors are benign and only few are malignant. Most of the caruncular tumors (either benign or malignant) are nevi. We report a case of a 75-year-old female patient presenting caruncular atypical late-onset junctional nevus that clinically arose malignancy suspicion. Ophthalmologic macroscopic examination and slit lamp examination of the right eye were performed. Further blood tests were performed. Carunclectomy was performed two days after admission to hospital. Microscopy revealed the junctional localization, diffuse proliferation of the nevocytes. Immunoreactions with S100 and human melanoma black 45 (HMB45) antibodies were performed. Differential diagnosis of these lesions represents a great challenge. The greatest challenge represents the differential diagnosis between a benign tumor and a malignant life-threatening one, the malignant melanoma, especially with unusual presentation. The presence of a late-onset caruncular tumor with uncertain evolution requires excision biopsy to determine the diagnosis and to establish the best management.
