Primary neuroendocrine carcinoma of the mediastinum

[摘要] A mediastinal mass was found in a 37 year old male who presented with fever, weight loss and fatigue. The chest CT revealed a 9×6×4 cm well circumscribed mass located paratracheally in the upper mid-mediastinum. The mass was removed by right thoracotomy. Macroscopically the tumor weighed 195 g and measured 9×6×4 cm. Microscopically the tumor consisted of small blue cells in solid and trabeculer patern. Immunohistochemical studies performed for differential diagnosis of small blue cell tumors. The tumor was diagnosed as primary neuroendocrine carcinoma of the mediastinum. This case is presented for its rare recurrence in that particular location.
