Introduction.Metastatic involvement of the mediastinal lymph nodes is an extremely uncommon finding in epithelial ovarian cancers.Case report.A 63-year-old woman was admitted to hospital for dyspnoea due to an anterior mediastinal mass. The surgical biopsy showed a 6-cm metastatic lymph node with a papillary pattern, scattered psammomas and immunoreactivity for WT1, Cytokeratin 7, EMA and negative for E-cadherin, GCFDP-15, Thyroglobulin, Cytokeratin 20, Cytokeratin 5/6, CEA, Vimentin, Calretinin, TTF1. After 20 months a follow-up CT identified an ovarian mass with the same histological pattern and immunoreactivity of the mediastinal nodule.Results.Immunohistochemistry, especially WT1, is useful in assessing the ovarian origin of an unusual metastasis particularly if it is the first presentation of the disease.
