Vulvar lipomas are a type of rare benign soft tissue tumor. This study describes 7 cases of vulvar lipomas in children, and it evaluates the clinical characteristics of this disease.
We performed a retrospective review of pediatric patients at our institution who were diagnosed with vulvar lipomas between January 1998 and December 2007.
Seven girls who were between the ages of 7 and 11 years were included in the study. In 6 cases, the lipomas were located on the right side of the vulva. In 4 of those 6 cases, the lipomas were found on the right anterolateral side. Five cases had gross swelling of the vulva with a poorly demarcated mass, but 2 cases had a well-demarcated or pedunculated mass. The initial tentative diagnoses made before imaging studies were right inguinal hernia in 4 cases and Bartholin's cyst in 2 cases. Preoperative imaging studies of ultrasound, computed tomography, and magnetic resonance imaging showed lipomatous characteristics of these tumors. All cases underwent surgical excision. Subsequent histopathologic examination demonstrated lipomas in each case.
Vulvar lipomas in children tend to occur on the right side, especially the right anterolateral side. It is necessary to differentiate this tumor from an inguinal hernia. Radiologic studies such as ultrasonography, computed tomography, and magnetic resonance imaging are useful for making the proper diagnosis. Surgical excision is the treatment of choice.
外阴脂肪瘤是一种罕见的良性软组织肿瘤。本研究描述了7例儿童外阴脂肪瘤病例，并评估了该疾病的临床特征。
我们对1998年1月至2007年12月在我院诊断为外阴脂肪瘤的儿科患者进行了回顾性研究。
7名年龄在7至11岁之间的女孩纳入了研究。6例脂肪瘤位于外阴右侧。在这6例中的4例中，脂肪瘤位于右前外侧。5例外阴有明显肿胀，肿块边界不清，但2例肿块边界清晰或有蒂。在影像学检查之前初步的初步诊断为4例右侧腹股沟疝和2例巴氏腺囊肿。术前超声、计算机断层扫描和磁共振成像等影像学检查显示了这些肿瘤的脂肪瘤特征。所有病例均接受了手术切除。随后的组织病理学检查证实每例均为脂肪瘤。
儿童外阴脂肪瘤倾向于发生在右侧，尤其是右前外侧。有必要将这种肿瘤与腹股沟疝区分开来。超声、计算机断层扫描和磁共振成像等放射学检查有助于做出正确诊断。手术切除是首选治疗方法。
