[Verrucous carcinoma of the penis. A report of 6 new cases and a review of the diagnostic and therapeutic aspects].

Verrucous carcinoma of the penis accounts for 5-17.8% of total carcinomas in the referred location that are diagnosed in our environment. Six cases of this rare neoplasia have been treated in our service and revised retrospectively. The epidemiological, clinical, diagnostic and therapeutic aspects of our series are analyzed and the issues around them discussed. Eventually, the benign biological behaviour of this tumour warranting conservative surgical treatment is ratified. In selected cases where the therapeutic modalities used do not yield material for histopathological analysis (laser, cryotherapy, etc.) prior obtention of a deep biopsy of the lesion to identify the likely presence of a well differentiated epidermoid carcinoma is imperative. Also, every effort should be made to monitor the cases of associated premalignant conditions.
