A tendon tumour presenting as a trigger finger

Area of Science:

• Pediatric Orthopedics
• Hand Surgery
• Musculoskeletal Tumors

Background:

• Trigger finger, or stenosing tenosynovitis, typically affects adults but can occur in children.
• Pediatric trigger finger is often idiopathic or congenital, with fewer reported cases linked to specific masses.
• Understanding the etiology of pediatric trigger finger is crucial for appropriate management.

Observation:

• A 14-year-old child presented with a trigger finger characterized by painful locking in the extended position.
• The locking was persistent and significantly impacted the child's daily activities.
• Clinical examination suggested a mechanical obstruction within the flexor tendon sheath.

Findings:

• Intraoperative findings revealed a tumor originating from the flexor digitorum superficialis tendon.
• Histopathological analysis confirmed the nature of the tumor (details not provided in abstract).
• Complete excision of the tumor was achieved during the surgical procedure.

Implications:

• This case highlights a rare cause of pediatric trigger finger: a tendon tumor.
• Surgical intervention for tumor removal can effectively treat trigger finger in pediatric patients.
• Further research into the incidence and characteristics of tendon tumors causing trigger finger in children is warranted.
