This is an account of 2 male surfing enthusiasts who recently sought care at our hospital after developing tumorous masses on their chins. Although the lesions appeared grossly benign, establishing a definitive treatment plan was perplexing because of the insidious nature of the protuberances. The lesion in the first patient was managed surgically. The approach was modified for the second patient because of information learned from the first. While the technical aspects of care management were simple, once the histologic structure of the tumor was defined, establishing an accurate clinical diagnosis before surgery was troublesome. The histologic findings for the lesion removed from the first patient consisted of primarily parenchymal fibrosis without concomitant structural abnormalities in overlying epidermis, suggesting that repetitive blunt trauma to the chin area while paddling the surfboard was probably the factor responsible for the pathogenesis of tumor formation. These findings and our experience in managing the 2 patients have formed the basis of this report.
