Seborrheic keratosis (SK) is a common epidermal tumor, consisting of a benign proliferation of immature keratinocytes. The natural history of SK is a slow progression over time and complete remission is not expected. The article presents the first case of a complete resolution of a large (2.5 cm diameter) SK lesion after hyperbaric oxygen therapy (HBOT). In addition to the case presentation, the pathophysiology of SK and the potential beneficial physiological effects of HBOT are reviewed and discussed.
