title: Malignant melanoma maxilla.
abstract: A malignant melanoma is a highly lethal melanocytic neoplasm. A neoplasm usually affects the skin. Malignant melanomas in the head and neck region are rare, accounting for less than 1% of all melanomas. Malignant melanoma of the nose and paranasal sinuses is an aggressive disease typically presenting at an advanced stage, with a 5-year survival rate ranging 20-30%. Melanomas are tumors arising from melanocytes, which are neuroectodermally derived cells located in the basal layers of the skin. This is a case report of a 35-year-old male, who presented with very aggressive disease and developed liver metastasis.
