Abstract
Aim. Demonstration of cases of melanoma of rare localization – with damage to the respiratory system. Materials and methods. A brief review of the literature on non-skin melanomas is presented; special attention is paid to melanomas of airways and lungs, primary localization and metastatic lesions. Clinical observations of this pathology are given. Results. The paper presents two rare cases from the personal practice of the authors: the diagnosis of primary melanoma of the paranasal sinuses with germination of the base of the skull and metastatic lung damage, in which it was difficult to determine the primary localization of the tumor. In both cases, differential diagnosis was carried out with other formations in the respective areas. The final diagnosis was made by histological and immunohistochemical studies. Conclusion. The diagnosis of melanoma with damage to the respiratory organs requires differential diagnosis with other formations of this localization. A histological and immunohistochemical study helps to establish the final diagnosis.
