| Summary: | Primary malignant melanoma of the external auditory canal is rarely reported. Malignant melanoma of the ear is estimated to occur in 1-4%
of all skin melanomas and about 7-20% of melanomas of the head and neck region. The pathophysiology of these tumours is different from
other skin lesions because of their anatomical and functional characteristics. The case presented is of a 11 year old female child with malignant melanoma of the external auditory canal confined to the right side, who initially presented with right ear pain, bleeding, post auricular
swelling and also a mass in the external auditory canal which was thought to be an aural polyp in the right ear. Excision of the tumour was
accomplished by a radical mastoidectomy. It was confirmed to be malignant melanoma after histopathological examination and Immunohistochemistry. Despite all efforts, the patient succumbed to the disease after receiving three cycles of chemotherapy. Even though this
malignancy is rarely found in the external auditory canal, it should be expanded into the differential diagnosis of an aural polyp and a post
aural abscess. The incidence, symptoms, investigations, treatment and prognosis of malignant melanoma of the external auditory canal is
discussed in this article. |
