Persistent Scalp Bump for 2 Years: Evaluation Needed

A scalp bump persisting two years is unlikely to resolve spontaneously and may indicate an underlying condition beyond the original trauma. Possible causes:

• Chronic inflammation or granuloma
• Benign tumors (lipoma, sebaceous cyst, dermatofibroma)
• Rarely, malignant lesions

Action: See a physician for examination. Imaging (X-ray, CT, MRI) may be needed. Treatment ranges from observation to excision based on diagnosis.
