Lipoma of the middle finger

Abstract

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.
