Abstract
Metastasis to the oral cavity from cutaneous melanoma is rare. Fewer than 30 cases of metastatic melanoma to the palatine tonsil have been reported in the literature, and only one of them was from Japan. Metastasis to the tonsil, without afferent lymphatics, suggests hematogenous dissemination and a poor prognosis.We present a case of metastatic melanoma restricted to the palatine tonsil. However, in this case, further metastasis has not been recognized in the one and a half years since the tonsillectomy of the metastasic tonsil. We discuss the favorable prognosis from the view point of the antigenic profile of the malenoma cells. [Skin Cancer (Japan) 2000; 15: 57-60]
