Taste and olfactory disturbances after treatment for acne with isotretinoin, a 13-cis-isomer of retinoic acid.

We report an olfactory disturbance after acne treatment with isotretinoin. A disturbance in taste was also reported by the patient. Examination of the nose showed no pathological findings. A CT scan was done to exclude a tumor or a lesion at the lamina cribrosa. Taste and smell examinations were performed and verified the lost qualities.
