Mesenteric Hemangiopericytoma Presenting as Acute Abdomen: Report of a Case
以急性腹症爲表現的腸系膜血管外皮細胞瘤：一病例報告
摘要
血管外皮細胞瘤是一種非常少見腫瘤，它源自外被細胞(pericytes)。這些血管外皮細胞瘤較常發現於四肢、後腹腔及鼻咽腔。此瘤常表現出侷限性復發，比遠端性轉移多。我們報告一42歲男性病例：患者分別在34歲及40歲時罹患鼻腔及頸部血管外皮瘤並接受手術治療。此個案因腹痛情形曾門診就醫，二天後因腹痛加劇被送至急診；經電腦斷層掃描發現一腸系膜腫瘤，且造成上腸系膜血管栓塞及腸腫脹。手術時發現位於腸系膜的一個大腫瘤且壓迫腸系膜根部血管，組織學為血管外皮細胞瘤與鼻腔及頸部腫瘤相同。回朔此患者病史，其罹患高度懷疑為轉移性血管外皮細胞瘤，無原腫瘤局部復發且源自腸系膜而以急性腹痛表現。
並列摘要
Hemangiopericytoma is an uncommon neoplasm arising from the pericyte of Zimmerman. This tumor is commonly found on the extremities, retroperitoneum, and nasopharynx. Hemangiopericytoma is found with local recurrence more often than distant metastasis. We report a 42 year-old man who developed mesenteric hemangiopericytoma 8 years after the resection and subsequent radiation therapy for the tumor at nasal cavity. This patient suffered from acute abdominal pain with peritoneal sign. The computed tomography showed a mesenteric tumor with superior mesenteric vein thrombosis and edematous intestine. The laparotomy revealed a large mesentery tumor compressing the root of mesentery to cause mesenteric ischemia. Histology confirms the diagnosis of hemangiopericytoma. Tracing back his history, we speculated that this patient had a hemangiopericytoma, arising from mesentery and presenting with acute symptoms.
