Mucosal malignant melanoma of the oral
cavity is an extremely rare condition. It has a poor prognosis. Here we report
two typical cases of malignant melanoma. In the first case, 64 years old man
developed an exophytic tumor in the hard palate. Head and neck and chest computerized
tomography scan showed a large aggressive tumor of the hard palate. The patient
also had multiple lung metastases and a cervical lymph node. The second case is
a 73 years old woman presenting a burgeoning mass on the right palate. Facial CT reveals a
malignant tumor lateralized in the right palate with ipsilateral metastatic
lymph nodes. Histological
with immunohistochemical studies assigned both cases to a malignant melanoma.
Due to the rarity of oral malignant melanomas, case reports are a necessary
source of information.
