Summary
A rare giant Buschke-Loewenstein tumour, a type of extensive genital wart caused by human papillomavirus type 6, infiltrated deeply into a patient's pelvic structures. Treatment with interferon-alpha showed no lasting effects.
Area of Science:
- Oncology
- Virology
- Dermatology
Background:
- Buschke-Loewenstein tumour (BLT) is a rare, aggressive, verrucous carcinoma of the anogenital region, often associated with human papillomavirus (HPV) infection.
- Giant BLTs can infiltrate extensively, posing significant surgical and reconstructive challenges.
Observation:
- A 42-year-old HIV-negative patient presented with a 12-year history of extensive genital warts and a coexisting verrucous carcinoma.
- The tumour masses infiltrated the external genitalia, perineum, buttocks, pelvic diaphragm, lesser pelvis, urethra, prostate, and urinary bladder.
Findings:
- Surgical intervention and plastic reconstruction were repeatedly required due to the extensive infiltration.
- Adjuvant interferon-alpha therapy provided no lasting therapeutic benefit.
- Human papillomavirus type 6 was identified as the causative agent via DNA in situ hybridization and Southern blot analysis.
Implications:
- This case highlights the aggressive nature and extensive infiltrative potential of giant Buschke-Loewenstein tumours.
- The limited efficacy of interferon-alpha suggests a need for novel therapeutic strategies for managing extensive HPV-associated anogenital cancers.
- Early detection and management are crucial for improving outcomes in patients with extensive HPV-related verrucous carcinomas.
