More than one factor may be involved. For example, a patient with eczema may subsequently develop black ear drainage. This would be suggestive of an accompanying fungus.
In diabetics or immune-suppressed individuals, chronic external otitis can become a very serious disease (malignant external otitis). Malignant external otitis is a misnomer because it is not a tumor or a cancer, but rather an aggressive bacterial (Pseudomonas) infection of the bone that can lead to infection of the base of the skull.
