Summary

A young woman presented to the outpatient gynaecology clinic with a rapidly growing bulky tumour located at the external genitalia, which she first noticed 10 days prior to her visit. Examination revealed a 6×3 cm cauliflower-like mass located on the left genitofemoral fold. The initial biopsy had several features suggestive of a human papilloma virus (HPV) infection. A broad excision of the mass was subsequently performed. The biopsy confirmed the presence of a large condyloma acuminatum. Condyloma acuminatum is a slow-growing benign exophytic tumour that is associated with HPV infection. In cases where the tumour has aggressive features, as in our patient, the differential diagnosis has to include carcinoma or Buschke-Löwenstein tumour. The initial biopsy of the tumour in our patient, however, excluded malignancy.
