To investigate the clinical characteristics and histological features of tumors in caruncles. Methods

We conducted a retrospective chart review of 126 eyes of 126 patients who underwent incisional or excisional biopsy of conjunctival masses between March 2008 and December 2016. Results

Twenty-four patients (19.0%) including 10 males and 14 females had a mass located on the caruncle. The mean age at diagnosis was 41.8 ± 13.4 years (range, 15–67 years). Most patients (75%) visited us for a cosmetically visible mass without other symptoms. The mean duration of symptoms was 73.8 ± 113.0 months (range, 1–240 months). The most common histological diagnosis was a melanocytic tumor (50%) followed by a sebaceous gland tumor (12.5%), an epidermoid cyst (12.5%), and papilloma (12.5%). The symptom duration of the melanocytic tumor was significantly longer than other types of tumors (153.6 ± 139.8 months, p = 0.025). Conclusions

Caruncular tumors accounted for 19% of all conjunctival tumors. The most common pathological diagnosis of a caruncular tumor was a melanocytic tumor, which had a characteristically long symptom duration.
