title: [Lymph node supraclavicular metastasis of thymic carcinoma: an inaugural and unusual feature of a rare disease].
abstract: Among the epithelial tumours of the thymus, thymic carcinomas are rare, involving more aggressive locoregional behaviour and a poor prognosis. More than one-third of cases present lymph node metastasis during an evaluation of the extension of a primitive mediastinal tumour of thymic origin. The authors report an unusual case in a 46-year-old woman presenting a metastatic form. The diagnosis of epidermoid thymic carcinoma was based on the histopathological examination of a right supraclavicular lymph node, associated with an anterior radiological mediastinal tumoral syndrome, raising the delicate problem of its diagnosis and treatment.
