RESULT: The diagnosis of verrucous carcinoma was difficult and depend on repeated biopsy. Verrucous carcinoma of larynx is a highly differentiated variant of squamous carcinoma that has peculiar clinical and morphological features. The basement membrane is not invaded. It is prone to distant metastasis, than to local recurrence. The case underwent the partial laryngectomy, and was followed up for more than 4 years with no recurrence. CONCLUSION: Verrucous carcinoma of the larynx is a special pattern of the well-differentiated squamous cancer. A correct diagnosis requires close cooperation between the laryngologist and the pathologist.
