Telomerase Activity in Giant Condyloma acuminatum

A 46-year-old male came to our hospital 1 month after noticing a 2-cm penile tumor. Since malignant findings such as atypical cells and mitosis were not observed in the frozen sections obtained at operation, the pathological diagnosis of this tumor was giant condyloma acuminatum. This tumor was analyzed by a telomeric repeat amplification protocol method, and telomerase activity was revealed. For comparison, a case of squamous cell carcinoma and a case of condyloma acuminatum were examined. Telomerase activity was observed in our case and in the case of squamous cell carcinoma. To our knowledge, this is the first case of telomerase activity in giant condyloma acuminatum ever reported. In addition to the histological examination, measurement of telomerase activity may provide valuable objective diagnostic information on evaluating the degree of malignancy of giant condyloma acuminatum and in obtaining a differential diagnosis between the benign and malignant.
