A Case of Primary Tracheal Malignant Melanoma / 결핵

ABSTRACT

We report a rare case of primary tracheal malignent melanoma documented by careful clinical examination. Differentiation between primary and metastatic malignant melanoma is very difficult. We conclude that this tracheal tumor is a primary malignant melanoma based on characteristic pathologic features and the exclusion of the possibility of spontaneous regression of the primary site by patient's history and physical examination.
