Nevus: 

The external auditory canal is an uncommon location for the nevi that are common benign tumours of the skin.

Melanoma:

Melanomas arising in the head and neck region comprise some 20% of all melanomas; of these, 7-15% occur in the vicinity of the external ear (most often on the helix).

Auricular melanomas, like those arising elsewhere, are rare in childhood and are most often first diagnosed in men in their 50s.

Melanomas of the external ear may present as flat pigmented lesions or as raised mass lesions, amelanotic (non-pigmented) variants exist as well.

Auricular melanomas are frequently recognized pathologically as either superficial spreading melanomas or nodular melanomas.

These tumors are aggressive, with a propensity for spreading to both regional lymph nodes and distant sites.

Key pathologic prognostic features of auricular melanomas include the histological subtype, tumor thickness, level of invasion and presence of ulceration.

Therapy includes both aggressive surgical attempts at excision in combination with sentinel node sampling in some instances and perhaps, adjuvant therapy as well.
