title: [Malignant recurrence of a penile cutaneous horn].
abstract: OBJECTIVE
  To report one case of malignant recurrence of a cutaneous horn of the glans penis.
  
  
  METHODS
  We report the case of a 66-year-old male patient presenting with penile discomfort over several months. Physical examination showed a corneal lesion in the glans-penis, the biopsy of which was reported as hyperkeratosis on top of pseudoepiteliomatous hyperplasia. Partial penectomy of the glans penis was performed after recurrence three months later.
  
  
  RESULTS
  Pathological study of the specimen identified a microinvasive squamous cell carcinoma in the base of the lesion. The patient is disease-free after two years of follow-up.
  
  
  CONCLUSIONS
  We emphasize the capacity the penile cutaneous horn has to become malignant. We also point out the need for observation of these lesions after excision.
