Koebner Phenomenon Triggered by External Dacryocystorhinostomy Scar in a Patient With Psoriasis: A Case Report and Literature Review

Koebner phenomenon is the development of isomorphic pathologic lesions on a wound of a patient with preexisting cutaneous disease, most commonly psoriasis. An elderly male with palmoplantar psoriasis developed periocular psoriasis in the form of blepharitis and conjunctivitis following an external dacryocystorhinostomy as a manifestation of Koebner phenomenon. Immediate diagnosis and treatment with topical steroids led to complete recovery. Thus, the authors report the first case of Koebner phenomenon in ophthalmic literature, with a review of previously published postsurgical cases of Koebnerization in psoriasis patients. All surgeons should be aware of its existence and warn susceptible patients regarding its occurrence. Accepted for publication September 3, 2017.
