Malignant Peritoneal Mesothelioma in a Pediatric Patient Presenting as Traumatic Hemoperitoneum

發生於一小兒科患者的惡性腹膜間質細胞瘤:以疑似創傷後腹膜出血的症狀表現

摘要


原發性惡性腹膜間質細胞瘤是一種罕見的癌症,特別是發生於小兒科的病人更是少見。我們因此報告一罕見發生於15歲小女孩身上的原發性惡性腹膜間質細胞瘤,她入院前出現腹膜出血、貧血,及腹部疼痛的症狀,且於入院三天前有明顯的腹部挫傷病史,急診的電腦斷層發現大量的腹水及在腹膜上有很多的高密度腫塊狀病兆,臨床上一開始誤認為是因為創傷後造成的腹膜出血及血塊,這名小女孩最後接受手術開刀治療,病理診斷確定是原發性惡性腹膜間質細胞瘤。

並列摘要


Primary diffuse malignant peritoneal mesothelioma (MPM) is a rare malignancy, especially in pediatric patients. We describe a 15-year-old girl with diffuse MPM presenting with bloody ascites, anemia, and abdominal pain, who had a history of blunt abdominal injury about 3 days before admission. Emergent computed tomographic (CT) scans revealed massive ascites with multiple high-density mass-like lesions occupying the mesentery and omentum. The initial clinical presentation was misdiagnosed as traumatic hemoperitoneum. The patient underwent exploratory laparotomy and histologic diagnosis was established by immunohistochemistry.
