Herpes Simplex Virus Dacryoadenitis Preceding Skin Vesicles

Herpes simplex virus involvement of the orbit is rare. We report the case of an immunocompetent patient who presented with preseptal edema, erythema, decreased vision, and dacryoadenitis prior to the appearance of vesicular skin lesions and in the absence of corneal dendrites. The patient's clinical picture failed to improve on empiric therapy with intravenous antibiotics. The patient subsequently developed skin vesicles and a nucleic acid amplification swab of the ocular surface was positive for herpes simplex virus-1. The patient demonstrated rapid clinical improvement after initiation of oral antivirals. This is an unusual case of presumed herpes simplex virus dacryoadenitis preceding skin vesicles in an immunocompetent patient.
