Primary carcinoma of the external auditory canal is extremely rare, with an incidence of approximately one per million populations per year. The commonest presenting symptom is reported to be pain followed by signs and symptoms of chronic suppurative otitis media.
A 28 year old male patient presented with polypoidal mass in left ear occluding external auditory canal since 3 months. Radical excision was done. The histopathology suggested poorly differentiated adenocarcinoma with surgical margins free. Patient received adjuvant radiotherapy (25 cycles, 50Gy).
Patient developed recurrence within 6 months for which wide excision of the mass along with excision of external auditory canal and a scalp rotation flap was performed. Patient was given concurrent chemoradiotherapy.
In such cases the need for adequate surgical excision has been stressed by many authors. Parotid gland involvement and perineural involvement are poor prognostic signs, associated with high chances of recurrence after surgical resection.
