Case Presentation: Herein a large achrochordon of the left labium majus is presented. Total excision of the lesion was performed and histopathology confirmed the diagnosis of achrochordon. Conclusion: Large skin tags on genitourinary region can be confused with a malignancy. Excision of these types of skin tags is recommended for pathological examination.展开更多

Some cases showed large polyps that might be misinterpreted as malignant tumors such as aggressive angiomyxoma. Aim: We report a case of bilateral fibroepithelial polyps in the labia minora in an adolescent age girl. Case Presentation: A 16 year-old-girl was referred to our department for the treatment of an enlarged skin-tag appearance lesion at the right sided labia minora. The lesion was resected and the microscopic finding was a fibroepithelial polyp. One year after the first operation the patient was again referred to our department for the treatment of a skin-tag lesion at the left sided labia minora. It was again resected and the pathological diagnosis was a fibroepithelial polyp. Conclusion: Fibroepithelial polyp of the labia minora is not common and it is often seen in adolescent girls and in young adults. Bilateral lesions and skin-tag appearance are especially rare. The lesion should be excised for obtaining the correct diagnosis.展开更多
