恶性神经鞘瘤常伴有上皮样细胞的特点,但良性的神经鞘瘤上皮样形态十分少见,被称为良性上皮样外周神经鞘膜瘤(benign epithelioid peripheral nerve sheath tumor,BEPNST)[1]。现收集1例左小腿良性上皮样神经鞘瘤伴左卵巢囊性成熟性畸胎瘤,报道如下。1临床资料患者女性,51岁,因“左小腿肿块12年近期增大伴体检发现左卵巢囊肿”于2006年12月来我院就诊并接受手术治疗。B超诊断左卵巢囊性畸胎瘤;CT显示左小腿肿块边界清晰,有钙化(Figure 1),考虑畸胎瘤。术中见腓肠肌内肿块表面有包膜与受累神经包膜相延续。
Malignant schwannoma often associated with epithelial-like cells, but the benign schwannoma epithelial like morphology is rare, known as benign epithelioid peripheral nerve sheath tumor (BEPNST) [1]. Now collect 1 case of left leg benign epithelial schwannoma with left ovarian cystic maturity teratoma, reported as follows. 1 Clinical data Female patients, 51 years old, because of “left leg mass 12 years recently increased with physical examination found that the left ovarian cyst” came to our hospital in December 2006 and received surgical treatment. B ultrasound diagnosis of left ovarian cystic teratoma; CT showed a clear left leg mass with calcification (Figure 1), consider teratoma. Intraoperative gastrocnemius see the surface of the capsule with the capsule and the involvement of the nerve capsule continued.
