title: The Contribution of Inflammatory Cell Infiltration to Conjunctival Inclusion Cyst Formation.
abstract: Purpose: The incidence of inclusion cysts was examined histopathologically in conjunctival disorders where inflammatory cell infiltration was seen in the subepithelial connective tissue.Method: The incidence of inclusion cysts was examined histopathologically in pterygium, vernal conjunctivitis, pyogenic granuloma and pingueculitis. The specimens of pinguecula were used as control.Results: Inclusion cysts were recognized in 5/(55) cases of pterygium, 2/(12) cases of vernal conjunctivitis, 1/(4) cases of pyogenic granuloma, and 1/(2) cases of pingueculitis. On the other hand no inclusion cyst was recognized in 20 cases of pinguecula in which no inflammatory cell infiltration was seen.Conclusions: Inflammatory cell infiltration may contribute to the formation of conjunctival inclusion cysts in pterygium, pingueculitis, vernal conjunctivitis and pyogenic granuloma.
