从1例34岁女性患者头皮切除了2个囊肿,1个光镜证实为杂合囊肿(毛发及表皮样混合),另1个囊内很多角蛋白显示角化不全,囊壁乳头瘤样增生,颗粒层增厚,并有空泡化细胞。对2个囊肿进行了抗人类乳头瘤病毒(HPV)抗原的免疫过氧化物酶标记。结果:“疣状囊肿壁”上的空泡化细胞标记阳性。 From a 34-year-old female patient, two cysts were removed from the scalp, one was confirmed as a heterozygous cyst by light microscopy (mixture of hair and epidermis), and many keratins in the other capsule showed parakeratosis and cystic papillomatous hyperplasia. The granular layer is thickened and there are vacuolated cells. Two cysts were subjected to immunoperoxidase labeling against human papillomavirus (HPV) antigen. RESULTS: The vacuolar cell markers on the “cystic cyst wall” were positive.
