Melanoma

Types of Melanoma

Melanoma can manifest in different types or conditions, each with its own characteristics and implications for treatment and prognosis. Some of the common types of melanoma include:

• Superficial Spreading Melanoma: This is the most common type of melanoma, typically characterized by horizontal growth along the top layer of skin before penetrating deeper layers. It often presents as asymmetrical lesions with irregular borders and variations in color.

• Nodular Melanoma: Nodular melanoma grows more rapidly and vertically than other types, often appearing as elevated nodules on the skin. Unlike superficial spreading melanoma, nodular melanomas may lack the typical asymmetry and color variations.

• Lentigo Maligna Melanoma: This subtype often develops on sun-damaged skin, particularly in older individuals. It initially presents as a flat, brown patch that gradually enlarges over time. Lentigo Maligna melanoma can be challenging to diagnose due to its subtle appearance.

• Acral Lentiginous Melanoma: Acral lentiginous melanoma occurs on hairless areas of the skin, such as the palms, soles, or beneath the nails. It often appears as dark-colored patches or streaks and is more common in people with darker skin tones.

• Amelanotic Melanoma: Unlike typical melanomas that exhibit pigment (melanin), amelanotic melanomas appear as flesh-colored or pink lesions. These can be challenging to diagnose visually, as they may resemble other benign skin conditions.

• Desmoplastic Melanoma: Desmoplastic melanoma is a rare subtype that presents as firm, flesh-colored or bluish nodules. It tends to occur on sun-exposed areas of the body and may be more aggressive than other types of melanoma.

• Mucosal Melanoma: Mucosal melanoma develops in the mucous membranes lining areas of the body such as the mouth, nasal passages, digestive tract, or genital areas. It is relatively rare but tends to be more aggressive and difficult to treat than cutaneous melanoma.

• Ocular Melanoma: Ocular melanoma occurs in the eye, specifically in the uvea (the middle layer of the eye). It can develop in the iris, ciliary body, or choroid and requires specialized treatment by ophthalmologists and oncologists.

Diaganosis

If you have a mole or other spot that looks suspicious, your doctor may remove it and look at it under the microscope to see if it contains cancer cells. This is called a biopsy.

After your doctor receives the skin biopsy results showing evidence of melanoma cells, the next step is to determine if the melanoma has spread. This is called staging. Once diagnosed, melanoma will be categorized based on several factors, such as how deeply it has spread and its appearance under the microscope. Tumor thickness is the most important characteristic in predicting outcomes.

There are several tests your doctor can use to stage your melanoma. Your doctor may use these tests:

• Sentinel Lymph Node Biopsy
• Magnetic Resonance Imaging (MRI) scan
• Positron Emission Tomography (PET) scan
• Blood work
