title: Athlete's nodule in a figure skater: an unusual presentation.
abstract: Sports-related acquired connective tissue nevus or "athlete's nodule" has been reported under a variety of different names. The lesion develops in response to activity causing chronic or repetitive low-grade pressure or irritation activity, which is often a component of athletic training. A case of "athlete's nodule" in a figure skater has been reported. Our case demonstrates the typical histopathologic findings of deposition of normal-appearing collagen bundles arranged haphazardly within the dermis as described in previous reports. Additionally, results of CD34, colloidal iron, and elastic tissue staining have been described. The macular clinical presentation with the absence of significant epidermal change is a unique presentation of athletic nodule. It is the goal of the authors to create increased awareness among pathologists and clinicians in identifying these lesions and to expand the clinical presentation to include nonprotuberant lesions.
