Summary
Pterygium inversum unguis, a nail abnormality, occurred in a man after a stroke. This case is unusual due to its association with neurological disorder and asymmetric distribution affecting fingers and toes.
Area of Science:
- Nail disorders
- Dermatology
- Neurology
Background:
- Pterygium inversum unguis is a nail condition characterized by the adherence of the nail bed/hyponychium to the nail plate.
- This adherence obliterates the distal groove, altering nail morphology.
Observation:
- A 50-year-old male patient developed pterygium inversum unguis following a stroke.
- The condition manifested asymmetrically on the right fingers and toes, correlating with right-sided paresis.
Findings:
- The case presents unique features including a link to a neurological disorder.
- Asymmetrical distribution, involvement of both digits and toes, and occurrence in a male patient are notable.
Implications:
- This case highlights a potential association between pterygium inversum unguis and cerebrovascular events.
- Further research may elucidate the pathophysiology linking neurological deficits to nail abnormalities.
- The findings expand the clinical spectrum of pterygium inversum unguis, suggesting broader etiologic considerations.
