Does oral melanoma grow?

·

Is oral melanoma flat or raised?

They could be flat or elevated with an erythematous border around it. Oral melanoma may appear in various forms including pigmented macule, pigmented nodule, or a large pigmented exophytic lesion or an amelanotic variant of any of these three forms.

How do I know if I have oral melanoma?

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.

Where does oral melanoma metastasize to?

The common location of primary oral malignant melanoma is the hard palate and maxillary alveolus. In ~85% of cases, the melanoma will metastasize to the liver, lung, bone and brain early in the course of the disease.

How common are oral melanomas?

Oral blue nevi are not reported to undergo malignant transformation. Oral melanomas are uncommon (1.2 cases per 10 million population per year in the United States), and, similar to their cutaneous counterparts, they are thought to arise primarily from melanocytes in the basal layer of the squamous mucosa.

Can oral melanoma be benign?

Although benign, intraoral melanocytic proliferations (nevi) occur and are potential sources of some oral melanomas; the sequence of events is poorly understood in the oral cavity. Currently, most oral melanomas are thought to arise de novo.

What is melanoma in the mouth?

The melanoma of the mouth is a malignant neoplasm of melanocytes. It is a rare entity accounting for only 0.5% of melanomas. There is a male predominance, and the median age at diagnosis is 55–66 years. The most common mouth sites of melanoma are the palate and maxillary gingiva.

Why have I got a lump in my mouth?

Such a lump may be caused by a gum or tooth abscess or by irritation. But, because any unusual growths in or around the mouth can be cancer, the growths should be checked by a doctor or dentist without delay.

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.

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.
