Nevoid melanoma

Nevoid melanoma is a rare form of melanoma, a type of skin cancer, that resembles a mole or nevus. It is often misdiagnosed due to its benign appearance.

Overview

Nevoid melanoma, also known as minimal deviation melanoma, is a variant of melanoma that can be difficult to diagnose due to its resemblance to a benign nevus. It is a rare form of melanoma, accounting for less than 1% of all melanoma cases.

Symptoms

Nevoid melanoma often appears as a small, brown or black, raised lesion on the skin. It may resemble a mole or nevus, and is often found on the trunk, head, or neck. The lesion may change in size, shape, or color over time.

Diagnosis

Diagnosis of nevoid melanoma can be challenging due to its resemblance to a benign nevus. A biopsy is typically required to confirm the diagnosis. The biopsy sample is examined under a microscope to look for abnormal cells.

Treatment

Treatment for nevoid melanoma typically involves surgical removal of the lesion. In some cases, additional treatments such as chemotherapy, radiation therapy, or immunotherapy may be recommended.

Prognosis

The prognosis for nevoid melanoma depends on a number of factors, including the size and location of the tumor, the patient's overall health, and whether the cancer has spread to other parts of the body.
