Summary
Giant lipomas of the hand are rare soft tissue tumors. Surgical resection of a large hand lipoma involving the ulnar nerve achieved complete recovery without recurrence.
Area of Science:
- Hand surgery
- Orthopedic oncology
- Soft tissue tumors
Background:
- Giant lipomas (>5 cm) of the hand are exceptionally rare soft tissue tumors.
- Lipomas are the most common benign soft tissue neoplasms.
Observation:
- A 49-year-old male presented with a large, fixed left hypothenar mass causing paresthesia in the ring and little fingers.
- Imaging revealed an 8x5x2 cm encapsulated, multilobulated mass.
- Histology confirmed a benign lipoma, with immunohistochemistry ruling out malignancy.
Findings:
- The mass necessitated temporary transection and subsequent microsurgical coaptation of the palmar digital branch of the ulnar nerve.
- Complete tumor excision was achieved.
- The patient experienced full sensory recovery within 6 months, with no signs of recurrence.
Implications:
- Meticulous en bloc resection of giant hand lipomas is feasible, even when involving critical neurovascular structures.
- Complete excision can yield excellent outcomes and prevent recurrence.
- Giant lipomas, though rare, require careful surgical planning to preserve function.
