Abstract
- Seborrheic keratosis is a common benign epidermal tumor. Although the etiology of seborrheic keratosis is unknown, a genetic predisposition, sun exposure and viral infection are possible factors. It also can be associated with auto-inoculation or chronic stimuli by friction. We experienced two cases of seborrheic keratosis with continuous arrangement along the frictional areas of the inguinal skin. Because there were no triggering factors, including sun exposure or human papilloma virus infection, we thought repetitive frictions or auto-inoculation might be related to these cases. Herein, we report on two cases of seborrheic keratosis that developed along the frictional areas of the inguinal skin.
