AB  - Malignancy of melanocytes, a pigment-producing cell, is referred as malignant melanoma (MM) which occur basically on skin and oral mucous membrane, but as well found in ears, eyes, gastrointestinal tract and genital mucosa. Oral melanomas has propensity to metastasise and invade more voluntarily than other malignant counterparts. Here we present a case of 52-year-old male patient with a chief symptom of blackening of gums in the upper front tooth region. In dental history, the patient revealed history of faulty artificial prosthesis fixed in the same region since 6 months. On the basis of a through clinical assessment, a provisional opinion of oral malignant melanoma, was prepared. On histopathological and immunohistochemical analysis with S-100 and homatropine methylbromide 45 the diagnosis of MM was confirmed.
