In males these lesions occur mainly in the pinna, in females in the external canal.

Squamous cell carcinoma of the pinna seems to be associated with a worse prognosis as compared to other locations.

Lesions arising from the inner part of external canal arises from the middle ear epithelium with destruction of the tympanic membrane.

Some authors recommend tumour excision with wide margins (5-10 mm) as first-line treatment.

Neck dissection with parotidectomy is indicated when suspicious lymph nodes are detected by ultrasound sonography, the tumour diameter is more than 4 cm, cartilaginous invasion is present, and vertical tumour thickness is more than 5 mm.
