“…Both patients and doctors tend to introduce a long 'Verschleppungszeit' [6,8], Our patient had a squamous cell carcinoma which showed clinical and histological features of condyloma acuminatum. Despite repeated attempts we were unable to discover virus particles as described in condyloma acu minatum in electron micrographs of the edge of the lesion [3,11,13], According to O riel [12], malignant changes in condyloma acuminatum must be regarded as rare, whether they occur as local, destructive invasions (the 'giant condyloma' of Buschke-Loewenstein) or as a malignant metas tasizing tumour [1], For example, Siegel [16] described a case of malignant changes in condyloma acuminatum of the anus, while O riel and W himster [13] demonstrated virus particles in a carcinoma of the anus in situ.…”
