Pachydermodactyly.

Area of Science:

• Pediatric Dermatology
• Clinical Case Study
• Hand Swelling Etiology

Background:

• A 16-year-old male presented with a two-year history of asymptomatic bilateral finger swelling.
• Previous evaluations by dermatologists and hand specialists failed to establish a diagnosis.
• The swelling initially affected the proximal left fourth digit, later spreading to other digits.

Observation:

• The patient denied pain, pruritus, restricted movement, morning stiffness, or trauma.
• A childhood habit of repetitive hand-rubbing was reported by the mother.
• The patient had a history of allergic rhinitis and asthma.

Findings:

• Persistent, asymptomatic swelling of multiple fingers across both hands.
• Absence of typical inflammatory or traumatic indicators.
• Lack of familial history for similar hand abnormalities.

Implications:

• Undiagnosed pediatric digital swelling requires thorough dermatological investigation.
• This case underscores the importance of considering less common etiologies in pediatric dermatology.
• Further research into the underlying causes of idiopathic digital swelling in adolescents is warranted.
