Exaggerated onychodermal band associated with unilateral racket thumb nail

Area of Science:

• Dermatology
• Nail Diseases
• Systemic Disease Manifestations

Background:

• Onychodermal bands are typically subtle nail findings.
• Racket thumb nail is a rare nail anomaly.
• Chronic renal disease can manifest with nail changes.

Observation:

• A 36-year-old primiparous female presented with exaggerated onychodermal bands.
• The patient also exhibited a unilateral racket thumb nail.
• Both conditions were observed in an otherwise healthy individual.

Findings:

• The case describes the co-occurrence of exaggerated onychodermal bands and a unilateral racket thumb nail.
• A review of exaggerated onychodermal bands and their association with chronic renal disease is provided.
• This represents a rare reported instance of both nail abnormalities in a single patient.

Implications:

• This case contributes to the limited dermatology literature on these specific nail abnormalities.
• Highlights the importance of considering systemic disease, such as chronic renal disease, in cases of exaggerated onychodermal bands.
• Underscores the need for further research into rare nail conditions and their potential underlying causes.
