Melanoma is an uncommon tumor and represents about 1.5% of all neoplasms. In the mediastinum, it presents as a primary neoplasm or metastasis. Diagnosis is essential for the adoption of the best therapy. Endosonography-guided fine needle aspiration (EUS-FNA) obtains cell samples and, when associated with other auxiliary exams such as immunohistochemistry, is useful to identify and differentiate primary and/or metastatic mediastinal lesions from a wide variety of other neoplasms. The endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) sensitivity is low and similar to endobronchial ultrasound-guided transbronchial needle biopsy (EBUS-TBNB) performed with the ProCore 25G or 22G needle. Thus, the diagnosis of this type of tumor becomes a great challenge. The authors report the first case in the literature of metastatic mediastinal melanoma derived from malignant cutaneous melanoma, which was submitted to Endosonography-guided fine needle biopsy (EUS-FNB) with the new ProCore 20G, to obtain tissue, being confirmed by histological examination of the specimens obtained with a single puncture.
