Soft Lump Between Shoulder Blades: Likely Lipoma—Evaluation and Options

A 6-inch, soft, mobile, non-tender mass between the scapulae is classic for a lipoma—a benign adipose tumor.

Lipoma Features

• Soft, doughy, movable, non-tender
• Subcutaneous; most common on back, neck, shoulders, thighs
• Size: pea to grapefruit+
• Not cancerous; malignant transformation (liposarcoma) is exceedingly rare

Other Considerations

• Epidermoid cyst (central punctum, cheesy material)
• Dermatofibroma (firm, dimples on pinch)
• Neurofibroma (may be tender/tingly)
• Rare: sarcoma (firm, fixed, rapidly growing, >5 cm)

Action

See a clinician for exam. Ultrasound or MRI if deep/atypical. Biopsy if suspicious. Asymptomatic lipomas can be monitored; excision if painful, cosmetic concern, or diagnostic uncertainty.
