Roy F. Sullivan, Ph.D. (1997)

This 64 year old female patient presented with a history of Bowen's disease, defined by her dermatologist as an "intraepithelial squamous cell carcinoma". Such a lesion had been surgically excised previously from the left facial area.

The patient was referred back to her dermatologist for an opinion concerning a soft, smooth, rounded growth (A) in the area of the left incsura intertragica. The neoplasm appeared to have enlarged over the last few years. The lesion was identified as an intradermal nevus with hair, a non-malignant condition.

The physician felt there was no contraindication to canal hearing aid use in the affected ear. Care was taken in morphological specification of a replacement canal hearing aid to avoid physical contact with the growth.(B)
