Summary
A lipoma, a benign adipose tissue tumor, is typically slow-growing and painless. This case report details the successful surgical resection and recovery of a large shoulder lipoma in a female patient.
Area of Science:
- Oncology
- Dermatology
- Surgical Pathology
Background:
- Lipomas are benign tumors originating from adipose tissue, commonly found subcutaneously.
- While generally painless and slow-growing, large lipomas can cause discomfort or nerve compression.
Observation:
- A 45-year-old female presented with a gradually enlarging right shoulder mass over 12 years, reaching 20 cm.
- Magnetic resonance imaging (MRI) confirmed a superficial, sizable lipoma without invasion of adjacent structures.
Findings:
- Surgical resection of the large shoulder lipoma was successfully performed.
- Histopathological analysis confirmed the benign nature of the adipose tissue tumor.
- Post-operative follow-up at 2, 4, and 6 months showed no recurrence and symptom resolution.
Implications:
- This case highlights the importance of surgical intervention for symptomatic or large lipomas.
- Complete resection and histopathological examination are crucial for definitive diagnosis and ruling out malignancy.
- Successful surgical management leads to symptom relief and favorable cosmetic outcomes.
