We present a case of 20-year-old woman who presented with a large pedunculated skin covered mass lesion arising from the left thigh, measuring 40 × 25 cm, with no history of pain or skin ulceration and a feeling of a lump with dragging pain in the left side of the abdomen for about 7 years. Subsequently, ultrasound, contrast-enhanced computed tomography, and magnetic resonance imaging of abdomen and left thigh region were carried out. The lesion was broad-based toward the left upper thigh with a central core of interspersed fat supplied by branches of the superficial and deep femoral arteries. Another lesion was seen in the left retroperitoneum anterior to the psoas muscle in a left paravertebral location encasing the left common iliac vessels extending into the left pelvic cavity and inguinal region inferiorly. The lesion showed dense post-acoustic shadowing on ultrasound, mild enhancement on contrast-enhanced computed tomography, and appeared hypointense on T1- and T2-weighted images. A left thigh lesion was excised, whereas incisional biopsy was done for the left retroperitoneal lesion. The diagnosis of a giant fibroepithelial polyp arising from the left thigh and left retroperitoneal fibromatosis was made. This is the first report of such a giant fibroepithelial polyp arising from the thigh with associated retroperitoneal fibromatosis.
我们报告一例20岁女性病例，该患者左大腿出现一个带蒂的巨大皮肤覆盖肿物，大小为40×25cm，无疼痛或皮肤溃疡史，左侧腹部有肿块感并伴有牵拉痛约7年。随后，对腹部和左大腿区域进行了超声、增强计算机断层扫描和磁共振成像检查。该病变以左大腿上部为基底，中央有由股浅动脉和股深动脉分支供血的散在脂肪核心。在腰大肌前方的左腹膜后，左椎旁位置可见另一病变，包绕左髂总血管，向下延伸至左盆腔和腹股沟区。该病变在超声上表现为明显的后方声影，在增强计算机断层扫描上轻度强化，在T1加权和T2加权图像上呈低信号。左大腿病变被切除，而左腹膜后病变进行了切开活检。诊断为左大腿巨大纤维上皮性息肉合并左腹膜后纤维瘤病。这是首例关于大腿部出现巨大纤维上皮性息肉并伴有腹膜后纤维瘤病的报告。
