Abstract
Case summary
A 73-year-old male visited our clinic with recurrent upper eyelid abscess over the previous 3 months. The patient did not have any evidence of external injuries, systemic inflammations, or any other specific findings. The best cor-rected visual acuity was 0.9 in the right and 0.5 in the left eye with normal IOP. Enhanced CT revealed a focal low density mass (11.3 × 12.6 × 10 mm) with peripheral enhancement. An excisional biopsy was performed. Histopathologic examina-tion revealed chronic inflammation and granulation tissue formation and the patient was diagnosed with Pott's puffy tumor. The patient experienced no discomfort after the excision biopsy. At the 14-month follow-up, there were no signs of recurrence.
