Frequent question: Which melanoma is locally aggressive?

Desmoplastic melanoma is rare, representing approximately 1.7% of all melanomas. This type of melanoma is locally aggressive and difficult to diagnose both clinically and microscopically. The majority of these tumors occur on the head and neck of elderly patients and one half are amelanotic.

Which type of melanoma is the most aggressive?

Nodular melanoma – This is the most aggressive form of cutaneous melanoma.

Is melanoma locally invasive?

Early melanomas

Stage I: The cancer is smaller than 1 mm in Breslow depth, and may or may not be ulcerated. It is localized but invasive, meaning that it has penetrated beneath the top layer into the next layer of skin.

Is Amelanotic melanoma more aggressive?

In itself, an amelanotic melanoma is no more dangerous than any other form of melanoma. Most people who are diagnosed and treated at an early stage survive. However, the fatality rates for amelanotic melanoma tend to be higher than for other types of melanoma.

What is locally advanced melanoma?

What are the chances of stage 1 melanoma returning?

Prognosis for Stage 1 Melanoma: With appropriate treatment, Stage I melanoma is highly curable. There is low risk for recurrence or metastasis. The 5-year survival rate as of 2018 for local melanoma, including Stage I, is 98.4%.

How deep is a wide local excision for melanoma?

Surgery (wide local excision)

The recommended margin is usually between 5 mm and 10 mm, depending on the type, thickness and site of the melanoma. For thicker tumours, a wider margin of up to 20 mm may be advised.

Can stage 1A melanoma spread?

A melanoma tumor is considered Stage I if it is up to 2 mm thick, and it may or may not have ulceration. There is no evidence the cancer has spread to lymph nodes or distant sites (metastasis). Stage I melanoma is local melanoma, meaning it has not spread beyond the primary tumor.

What does locally advanced mean?
