Abstract
Background: Pyogenic granuloma is a vasoproliferative inflammatory response composed of granulation tissue. The pathogenesis is not entirely clear. We describe a series of patients with pyogenic granulomas occurring following common oculoplastic procedures and propose a common etiology. Methods: Sixteen cases of pyogenic granuloma that occurred after various oc uloplastic procedures from 1991 to 2000 were collected from the files of tw o oculoplastic surgeons. Results: Pyogenic granulomas were found to occur at surgical and nonsurgica l sites associated with tissue irritation or inflammation or both. Interpretation: Capillaries are a predominant component of wound healing an d pyogenic granulomas. The growth and development of new capillaries follow s an orderly sequence of events that is highly regulated by a variety of an giogenic factors. We postulate an imbalance in angiogenesis regulation as t he common pathway for pyogenic granuloma development.
