Dacryops and clinical diagnostic challenges

      Abstract

      Objective

      The study aims to describe the clinical and histopathologic features of different types of dacryops and their clinical diagnostic challenges.

      Methods

      This is a retrospective cohort study of all surgically excised cases of dacryops in 2 tertiary eye hospitals in Riyadh, Saudi Arabia.

      Results

      The study included 58 dacryops specimens from 55 patients with an average age of 41.2 years (range, 4–78 years). The most common location was the upper lid (60.3%), whereas the least expected location was the caruncle (6.9%). The most common site of dacryops occurrence was in the accessory lacrimal gland (55.2%), the main lacrimal gland (32.8%), and then ectopic dacryops (12%). All patients presented with lid swelling alone except for 3 patients who experienced secondary mechanical ptosis. On physical examination, conjunctival scarring existed in 4 patients (6.9%). Preoperative diagnosis of dacryops was accurate in 44.8% of the cases. Dacryops of the main lacrimal gland was accurately diagnosed clinically in all cases compared with other locations, which was statistically significant (p < 0.001). The causes of inaccurate clinical diagnoses were hidrocystoma (26.9%), inclusion cyst (11.5%), and dermoid cyst (7.7%), whereas the remaining cases were diagnosed as cysts without a specific subtype (53.9%). Recurrence of the lesion was observed in 2 cases (3.5%). No clinical or histopathologic factors were associated with a risk of recurrence.

      Conclusion

      Dacryops can represent a diagnostic challenge to ophthalmologists. Familiarity with clinical presentations and findings is required to diagnose dacryops outside the main lacrimal gland.
