肝脏未分化胚胎性肉瘤的研究进展

肝脏未分化胚胎性肉瘤（undifferentiated embryonal sarcoma of the liver，UESL）是发生于肝脏的高度恶性间叶源性肿瘤，常累及儿童及青少年，偶发于成人。UESL发病机制未知，发病隐匿，术前确诊率低且术后易复发，预后差。UESL特异性诊断标志物、分子生物学特征等尚待研究，主要依靠病理诊断进行确诊。手术、化疗和放疗的多模式治疗可显著改善UESL患者的预后。肝移植治疗也可以作为部分UESL患者的一种治疗手段。本综述拟从UESL的临床症状、组织病理学特点、发病机制、鉴别诊断、治疗及预后等方面进行介绍。

Undifferentiated embryonal sarcoma of the liver: case report and literature survey

Undifferentiated embryonal sarcoma (UES) of the liver was first identified as an independent clinicopathologic type of sarcoma in 1978. It is an uncommon hepatic tumor, of mesenchymal origin, usually observed in children, and cases in adults are rare: to our best knowledge, reports of only 51 cases have been published in the past 50 years. We present a case of UES of the liver in a previously healthy 22 year-old woman, admitted to our hospital due to a palpable mass in the right upper abdomen. On admission, laboratory studies showed mildly elevated aspartate aminotransferase, alkaline phosphatase, and gamma-GPT. Hepatitis and tumor markers were negative. Ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) showed a large mass involving the right lobe and the medial segment of the liver, with compression of the bile duct. Right trisectionectomy with bile duct resection and reconstruction was performed. Microscopically, the tumor was composed of pleomorphic spindle cells in a myxoid stroma with focal staining of S-100 by immunohistochemistry. The histologic diagnosis was UES. Adjuvant therapy with vincristine, actinomycin-D, and cyclophosphamide was performed, and at 14 months of follow-up, the patient is alive without any evidence of recurrence. The clinical and histopathological features, as well as the therapeutic choices for adult UES, are described for this patient and in the literature of the past 50 years.

Poorly differentiated sarcoma of the prostate causing obstructive acute renal failure: A case report

A 12-year-old boy presented to the Naha Municipal Hospital complaining of back pain. After intravenous pyelography, computed tomography, magnetic resonance imaging, ultrasonography and biopsy, he was suspected to have sarcoma of the prostate and was referred to the University of the Ryukyus Hospital. Acute renal failure of the post renal type was evident, accompanied by minimal hydronephrosis. Emergency hemodialysis and right ureterostomy were performed, as was a transurethral prostate biopsy. The specimen showed a poorly differentiated sarcoma not otherwise classifiable. After recovery from surgery, chemotherapy was attempted over 2 months, but the patient died of tumor 250 days after admission.
