Rationale:Lipomas originated from fingers are rare and the dissection is necessary when the lipomas limit the finger movement or cause pain.Patient concerns:A 57-year-old male was admitted to our department due to a painless swelling on the volar side of the middle finger of the right hand. The flexion movement of the distal interphalangeal joint was limited.Diagnoses: Imaging studies and open biopsy confirmed that it was a finger lipoma.Interventions: An excisional biopsy was performed.Outcomes: The patient recovered completely after two weeks.Lessons: Based on this case and literature we reviewed, ultrasound and MRI should be used to diagnose the finger lipoma and excision was the main treatment option.
