Summary
Knuckle pads are benign growths typically on fingers, but can appear on feet due to friction. This case highlights acquired knuckle pads on the feet caused by athletic gear.
Area of Science:
- Dermatology
- Pathology
Background:
- Knuckle pads are benign, asymptomatic skin growths commonly found on the fingers.
- They can be inherited or acquired, with acquired forms linked to repetitive friction and trauma.
- While typically affecting the hands, knuckle pads on the feet are less common and have been associated with genetic syndromes.
Observation:
- This report details an unusual case of acquired knuckle pads on the feet.
- The patient presented with lesions secondary to repetitive friction from athletic gear.
- This presentation differs from typical inherited syndromes associated with foot knuckle pads.
Findings:
- Histological examination reveals characteristic features of knuckle pads, including hyperkeratosis, hypergranulosis, and thickened collagen bundles.
- The findings support the association between repetitive friction from external sources, like athletic gear, and the development of acquired knuckle pads on the feet.
- This case expands the understanding of etiological factors for foot knuckle pads beyond inherited conditions.
Implications:
- Recognizing friction as a cause for foot knuckle pads is crucial for accurate diagnosis and management.
- This finding may prompt further investigation into environmental and occupational factors contributing to knuckle pad development.
- Dermatologists should consider repetitive friction from footwear or athletic equipment in the differential diagnosis of foot lesions.
