Abstract:
A 16-year-old boy presented with a number of asymptomatic pigmented macules on the volar aspect of his index fingers. Dermoscopy of each macule revealed a parallel ridge pattern of homogenous reddish-brown pigment. We propose that these lesions were induced by repetitive trauma from a Sony PlayStation 3 (Sony Corporation, Tokyo, Japan) vibration feedback controller. The lesions completely resolved following abstinence from gaming over a number of weeks. Although the parallel ridge pattern is typically the hallmark for early acral lentiginous melanoma, it may be observed in a limited number of benign entities, including subcorneal haematoma.
Insights
Gaming-induced finger lesions in a teen resolved after stopping play. Dermoscopy showed a parallel ridge pattern, usually linked to melanoma, but here caused by repetitive trauma from a game controller.
Area of Science:
- Dermatology
- Medical Devices
- Adolescent Medicine
Background:
- Repetitive trauma can cause skin changes.
- The parallel ridge pattern on dermoscopy is a key diagnostic feature.
Observation:
- A 16-year-old boy presented with asymptomatic pigmented macules on his index fingers.
- Dermoscopy revealed a homogenous reddish-brown pigment in a parallel ridge pattern.
Findings:
- The lesions were attributed to repetitive trauma from a Sony PlayStation 3 vibration feedback controller.
- Complete resolution occurred after a period of gaming abstinence.
Implications:
- The parallel ridge pattern, while often associated with acral lentiginous melanoma, can be seen in benign conditions like subcorneal hematoma.
- This case highlights a novel, trauma-induced cause of pigmented macules in adolescents related to video gaming devices.
