Аннотация
INTRODUCTION: Primary mediastinal tumors are rare diseases including a broad spectrum of pathologies ranging from the well-known, such as lymphoma, thymoma or germ-line tumors to some very unusual presentations.
CASE REPORT: We describe a solitary mediastinal mass compressing the bronchial and vascular system in a patient suffering from chronic dyspnea. Diagnosis, obtained by means of a CT-guided biopsy, was a melanoma without any sign of a primary cutaneous lesion which harbored the BRAF V600E mutation.
CONCLUSIONS: An exclusive mediastinal presentation of a malignant melanoma is exceptional and, in the context of BRAF mutation needs to be considered and diagnosed given the potential therapeutic impact.
