Background: Human papillomavirus infections are difficult to treat and have a high rate of recurrence, especially in a setting of human immunodeficiency (HIV) infection. Moreover, there is no standard treatment for oral condylomas.
Patients and methods: We report the partial success of in situ injections of cidofovir in an HIV patient, presenting extensive oral condylomas. The injections were well tolerated and the response was still present at one year while the immune status of the patient was unchanged.
Discussion: The efficacy of topical cidofovir against condyloma acuminata has been reported and the value of in situ cidofovir injections for the treatment of laryngeal papillomatosis is well established. This case report shows the need for further investigation of in situ cidofovir injections as an alternative treatment for human papillomavirus lesions that are difficult to treat because of both site and extension.
