Pictures provided by the National Center for Biotechnology Information help medical professionals distinguish between types of cancerous toenails and recognize nail problems not caused by tumors. Longitudinal melanonychia is characterized by a band of color or melanin that runs the length of the nail, while amelanotic cancer does not make melanin so the color of the tumor is lighter. This lack of melanin often causes the tumor to blend into the skin underneath the nail, making it harder to identify and diagnose, explains Bristow et al.

A fungal infection and subungual haematoma underneath a toenail can be mistaken for cancerous tumors, according to Bristow et al. A subungual haematoma is a blood clot located underneath a toenail that resembles a tumor. Although a haematoma is not necessarily caused by a tumor, it is a possibility. It can also be caused by trauma to the toe. A fungal infection from lichen planus can manifest on the skin beneath a nail and resemble a longitudinal melanonychia tumor. Occasionally, the bacterium pseudomonas can infect the nail and cause it to turn green or black.
