Pathology
- A combination of junctional activity at the dermo-epidermal junction together with the presence in the dermis of the heavily pigmented bipolar dendritic cells found in a blue naevus
Key diagnostic features
- Frequently quite large and may have an irregular border
- Often show features consistent with their dual origin with a brown component and blue-black component
Management
- Although benign, these lesions are usually excised with a 2 mm margin of normal skin to confirm the diagnosis and exclude melanoma
