A dermatologist may find it difficult to definitively tell the difference between a keratosis and nodular melanoma just by using a scope. Nodular melanoma can resemble other skin lesions, such as blood blisters or benign growths. Therefore, if a dermatologist suspects nodular melanoma, they may perform an excisional biopsy to remove the entire skin tumor and examine it under a microscope for melanoma cells.

Key points:
- Nodular melanoma can look like other skin lesions.
- An excisional biopsy is often performed for a definitive diagnosis.
