Can melanoma spread to the tongue?

·

What is melanoma on tongue?

Oral melanomas may present as flat, brown or black macules, nodules or ulcerated lesions on gingiva, palate, lips, and very rarely on tongue. The prognosis for mucosal melanoma is worse than cutaneous lesions. Amelanotic melanoma is characterized by the absence of melanin pigment altogether.

What does an oral melanoma look like?

Oral melanomas are often silent with minimal symptoms until the advanced stage. The lesions can appear as pigmented dark brown to blue-black lesions or apigmented mucosa-colored or white lesions on physical examination. Erythema may be present if inflammation is present.

Can you have melanoma in the mouth?

Because oral malignant melanomas are often clinically silent, they can be confused with a number of asymptomatic, benign, pigmented lesions. Oral melanomas are largely macular, but nodular and even pedunculated lesions occur. Pain, ulceration, and bleeding are rare in oral melanoma until late in the disease.

What color is oral melanoma?

The most common presentation of oral melanomas is an asymptomatic brown, dark blue or black macule, sometimes with erythema or ulceration. A more advanced disease may take a nodular surface characteristics, they may also exhibit asymmetric, and irregular borders just like cutaneous melanomas (Elder et al., 1993).

What is oral malignant melanoma?

Oral malignant melanoma (OMM) was first described by Weber in 1859.[1] Malignant melanoma of the oral cavity is an extremely rare tumor arising from the uncontrolled growth of melanocytes found in the basal layer of the oral mucous membranes.[1,2] Melanocytes are neural crest-derived cells that migrate to the skin, …

How common is melanoma in mouth?

In a review of the large studies, melanoma of the oral cavity is reported to account for 0.2-8% of melanomas and approximately 1.6% of all malignancies of the head and neck. In some studies, primary lesions of the lip and nasal cavity also are included in the statistics, thereby increasing the incidence.

Can melanoma be cured?

A cure is often possible. Melanoma is found in the outer layers of skin and in the lower layers of the dermis. The likelihood of a cure is still good. The cancer cells have spread beyond the skin and are found in a lymph node(s) or lymph vessel(s) closest to where the melanoma began.

How common is melanoma on the lip?

Background. Malignant melanoma of oral cavity is a rare condition, accounting for 0.5 % of all oral malignancies and about 1–2 % of all melanomas. Oral melanomas have extremely poor prognosis with 5 years survival rate of 12.3 %.

What causes oral mucosal melanoma?

It arises primarily from melanocytes found in the basal cell layer of the epithelium, but may sometimes arise from melanocytes residing in the lamina propria. The pathogenesis is complex, and few of the molecular mechanisms underlying the development of oral mucosal melanoma have been defined.

What is mucosal melanoma?

Mucosal melanoma is a rare type of melanoma that occurs on mucosal surfaces. Mucous membranes are moist surfaces that line cavities within the body. This means that mucosal melanoma can be found in the respiratory tract, gastrointestinal tract or genitourinary tract.

Do you feel ill with melanoma?

They don’t feel ill. The only difference they notice is the suspicious-looking spot. That spot doesn’t have to itch, bleed, or feel painful. Although, skin cancer sometimes does.

How long does it take for melanoma to metastasize?

214 patients with MM were evaluated retrospectively. Distant metastases (82%) were the most frequent for patients initially metastatic. The median and 1-year survival rates of initially MM patients were 10 months and 41%, respectively. The median time to metastasis for patients with localized disease was 28 months.

How can you tell if melanoma has metastasized?

Metastatic melanoma symptoms and signs may include:

  • Fatigue.
  • Swollen or painful lymph nodes.
  • Weight loss.
  • Loss of appetite.
  • Trouble breathing or a cough that doesn’t go away.
  • Bone pain.
  • Headaches.
  • Seizures.
