自Pinkus 1953年首先报道本病以来,普遍认为纤维上皮瘤特别好发在腰骶和背部。但是,本文作者在70例纤维上皮瘤患者中,发现其中31例的肿瘤部位不是腰骶和背。31例中女性10侧,男性21例。临床表现呈多形性,需与原位癌、类Paget基底细胞上皮瘤、脂溢性疣、传染性软疣、细胞痣(Naevus cellulaire)、乳头状瘤进行鉴别诊断。病程常很长,本组中最长者15年。31例中的20例已经变成或正在变为基底细胞上皮瘤,即约占 Since Pinkus first reported the disease in 1953, it was generally believed that fibrous epithelial tumors developed particularly well in the lumbosacral and back. However, the authors found that among the 70 patients with fibroepithelial neoplasia, 31 of them had tumor sites that were not lumbosacral and dorsal. In 31 cases, there were 10 females and 21 males. The clinical manifestations were pleomorphic and required differential diagnosis with carcinoma in situ, Paget’s basal cell epithelial tumor, seborrheic hernia, molluscum contagiosum, nevus cellulaire, and papilloma. The course of the disease is often very long. The longest in this group is 15 years. Twenty of 31 cases have become or are becoming basal cell epithelial tumors,
