Epidermoid Carcinoma :
95% percent of penile cancer is epidermoid, or squamous cell carcinoma. Epidermoid carcinoma  develops from squamous cells. This scale like skin cells can develop anywhere on the organ usually found in the glans but may occur on the corona glandis and rarely, in the preputial cavity.

Verrucous Carcinoma :
Verrucous carcinoma also called Buschke-Lowenstein tumor is an uncommon form of squamous cell carcinoma  This low-grade tumor can occur on the genitals, skin, mouth, larynx and anus. These tumors rarely spread outside of the penis and it is often difficult to distinguish this condition from a benign genital wart.

Adenocarcinoma :
A very rare type of penile cancer called adenocarcinoma can develop in thee sweat glands in the skin of the penis.These tumors have the potential to invade below the skin and may eventually spread to lymph nodes.

Melanoma :
Another small percentage of penile cancer can develop in the pigment producing cells of the skin on the penis. These are called melanomas. Melanomas are considered more dangerous because they grow and spread quickly. Usually melanomas develop on sun-exposed areas of the skin, though occasionally they develop on other areas not likely to be sunburned. Usually appear as blue-brown flat growths and tend to spread more rapidly and more widely.

Basal Cell Cancer :
Less than 2% of penile cancers are basal cell cancers and are slow-growing tumors that rarely spreads to other body parts. These tumors develop in skin cells.

Sarcomas :
Sarcomas develop from the blood vessels, smooth muscle and other parts of the penis.  About 1% of penile cancers are sarcomas.
