Abstract
Malignant melanoma of the nasal cavity or para-nasal cavity is very rare. The authors reported here a rare case of malignant melanoma occurring in the left middle meatus of the nose, a woman of 51 years of age.
She had suffered from left nasal obstruction and nasal bleeding for 2 years. The examination revealed that blackish-brown tumor filled the left nasal cavity. The tumor was extirpated operatively by left maxillectomy combined with an evidement of the neck. The tumor had involved the anterior part of the left ethmoidal cells, the soft palate and the outside wall of the middle meatus.
The orbit and the posterior wall of the maxillar sinus had not been invaded. It was ascertained that the tumor cells contained melanin pigment by the histological research of the extirpated tumor.
Irradiation and chemotherapy were made after the operation, but she died after 6 months of the operation owing to wide metastasis to the left mandibular angle and to the abdominal and back skin.
