Core Tip

Core tip: We report a case of condyloma acuminatum (CA) in a patient who underwent endoscopic submucosal dissection (ESD). Although most cases of CA have been treated with surgery or immunotherapeutic techniques, the rate of local recurrence is high because of difficulty detecting a precise margin of the lesion, especially those located in the anal canal. ESD enables detection of the lesion with magnification chromoendoscopy and treatment in the endoscopic visual field; thereby achieving en-bloc resection. ESD provides precise histopathological evaluation and could be an alternative method for CA that prevents recurrence.
