Abstract:
A 15-year-old boy presented with a two-year history of subcutaneous nodules on his feet that were painful on palpation and with footwear. The patient is an avid gamer, and his mother had noted a distinct sitting position as he sat playing his console. Skin biopsy showed features of a collagenoma, consistent with previous reports of repetitive pressure lesions associated with various sports and religious practices. It is important to be aware of these "gamer's nodules" that result from prolonged periods of fixed seating postures.
