Squamous cell carcinoma of the nasal septum mucosa.

Primary squamous cell carcinomas of the nasal septum constitute only 9% of all malignant tumors of the nasal cavity. We present 16 cases occurring during a 14-year period. As the initial signs of these carcinomas are no different from non-neoplastic disease, a high index of suspicion is necessary in order to correctly diagnose these lesions. It seems to us that when the diagnosis of nasal septum carcinoma is established, the best method of treatment is wide surgical excision and immediate repair of the defect by a split-skin graft.
