Clinical analysis of conjunctival papilloma

Abstract

Objective: To summarize and analyze the clinical manifestation of conjunctival papilloma, its relationship with human papillomavirus (HPV) infection and the recurrence after the combination of operation and pharmacotherapy. Methods: A retrospective case series study. Analysis of 40 patients (41 eyes) with conjunctival papilloma treated at Peking Union Medical College Hospital from January 2008 to June 2018 was performed. All patients were given routine blood and urine, hepatitis B virus surface antigen, antibodies to hepatitis C virus, antibodies to human immunodeficiency virus and antibodies to Treponema pallidum testing, and HPV testing for the urethra epithelial tissue. Direct contact of the tumor with instruments was avoided during surgery, and freezing treatment was combined. HPV testing was performed for the resected conjunctival papilloma. Multiple medications were used after surgery. Results: In 40 cases with 41 eyes, there were 22 males (23 eyes) and 18 females (18 eyes). A single tumor was seen in 27 eyes, and multiple tumors were seen in 14 eyes. Thirteen patients (13 eyes) older than 50 years old had pedicel-free papillpma, and 27 patients (28 eyes) aged from 12 to 40 years had pedicel-type papillpma. All cases were confirmed by pathology as conjunctival papilloma, of which 9 cases showed moderate to severe atypical hyperplasia on squamous cells. The HPV test was positive in 17 out of the 40 cases (42.5%) of conjunctival papilloma. Urine test results of 16 patients (40.0%) were positive for occult blood and showed that urinary white blood cell was elevated. Of the 40 patients, 33 were newly diagnosed and 7 had a relapse. The average follow-up time was (37.4±11.9) months after combined therapy and no recurrence was found in any patients. Conclusions: Conjunctival papilloma is usually observed in people aged from 20 to 40 years and older than 50 years, and it often occurs in one eye. Its main pathological feature is benign tumors of the papillary hyperplasia on the conjunctival epithelial tissue. Some patients have atypical hyperplasia of squamous cells. The cause of the disease may be related to the infection of HPV and the urinary tract. Combined treatment can reduce the recurrence rate of conjunctival papilloma.
