Thymoma, a rare epithelial neoplasm, is the most common anterior-superior mediastinal tumour. Thymoma can occur sporadically or in association with other conditions, such as myasthenia gravis, pure red cell aplasia (PRCA), and hypogammaglobulinemia. Only 5% of thymoma cases develop PRCA; however, 10-50% of patients presenting with PRCA have an associated spindle cell type thymoma. Thymoma complicated by PRCA is associated with a poor outcome. We report the case of a 38-year-old female who presented with chest pain, and was diagnosed with an anterior mediastinal mass. A thymectomy was performed, and histopathological examination revealed mixed thymoma; two months later, the patient developed PRCA. The present case reinforces the need for clinicians to be vigilant with thymoma patients, even following thymectomy.
胸腺瘤是一种罕见的上皮性肿瘤,是前上纵隔最常见的肿瘤。胸腺瘤可散发性发生或与其他疾病相关,如重症肌无力、纯红细胞再生障碍性贫血(PRCA)和低丙种球蛋白血症。只有5%的胸腺瘤病例会发展为PRCA;然而,10%-50%出现PRCA的患者伴有梭形细胞型胸腺瘤。并发PRCA的胸腺瘤预后较差。我们报告一例38岁女性,因胸痛就诊,被诊断为前纵隔肿块。行胸腺切除术,组织病理学检查显示为混合型胸腺瘤;两个月后,患者发展为PRCA。本病例强化了临床医生即使在胸腺切除术后也需对胸腺瘤患者保持警惕的必要性。
