title: Tick Infestation of the Eyelid With Histopathologic Characterization.
abstract: Ocular tick infestation is a rare occurrence. The authors report a case that is unique for being the first published example from New England, for its chronic presentation, and for the inclusion of histopathologic analysis in its diagnostic workup. A 75-year-old man was evaluated for a persistent eyelid growth secondary to an incompletely removed tick that had attached 6 months earlier. The lesion was completely excised, and a partially destroyed arthropod was observed embedded within the tissue. Light microscopy demonstrated a mixed granulomatous reaction. Given the disruption of the tick's anatomy, speciation could not be performed. The patient had an uneventful recovery. A corresponding review of tick bites to the eye is provided.
